SORBENT DEVICES FOR AIR INTAKES

Abstract

Absorbent sheet products, which include absorbent sheets and at least one porous cover layer, are bonded to an internal wall surface defined by an air inlet. The absorbent sheets collect vapors, such as hydrocarbon vapors, from engine components like the combustion chamber, injectors, carburetor, fuel ports, crankcase, or other engine parts, thereby reducing evaporative emissions. In certain configurations, the absorbent sheet product includes an edge seal that improves handling during the manufacturing process.

Description

SORBENT DEVICES FOR AIR INTAKES CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to the United States provisional application Serial Number 62 / 884,458 filed on August 8, 2019, the contents of which are incorporated herein by reference in their entirety. BACKGROUND: Evaporative emissions from gasoline and other hydrocarbon fuels are a major source of air pollution because the various hydrocarbons contained in these fuels can form photochemical smog when exposed to sunlight. The compounds in this smog, along with the hydrocarbons themselves, have detrimental effects on the health of humans and animals, as well as causing environmental damage. These emissions are typically controlled by placing an sorbent canister in the fuel tank of cars, trucks, and other vehicles. When the engine is off, the sorbent canister adsorbs excess hydrocarbon emissions from the fuel tank. Conversely, when the engine is running, the canister is purged with fresh air, which is then directed to the engine's air intake so that the purged fuel vapors can be burned by the engine. However, vehicle fuel systems include countless locations where hydrocarbon vapors can escape and contribute to evaporative emissions. Additionally, many agencies, such as the Environmental Protection Agency (EPA), have implemented stricter hydrocarbon emission limits. These realities mean that new ways of capturing hydrocarbon vapor emissions must be developed. Current efforts focus on incorporating sorbent materials into engine air intakes, further reducing hydrocarbon emissions that would otherwise emanate from the intake manifold due to its proximity to the combustion chamber and fuel injectors. To date, these materials have taken the form of a small bag of granular activated carbon or a piece of paper made with added powdered activated carbon.The first system suffers from concerns about dust generation, increased pressure drop, and poor utilization of the activated carbon inside the bag. The latter system experiences activated carbon fouling due to the paper manufacturing process, thus compromising capacity and kinetics, as well as incurring high costs. There is a need for improved sorbent devices to adsorb and / or absorb hydrocarbon vapors from vehicle air intakes.

DETAILED DESCRIPTION Before describing the present compositions and methods, it should be understood that this invention is not limited to the particular processes, compositions, or methodologies described, as these may vary. It should also be understood that the terminology used in the description is intended to describe the particular versions or embodiments only and is not intended to limit the scope of the present invention, which is limited only by the appended claims. Unless otherwise defined, all technical and scientific terms used in this description have the same meaning commonly understood by a person skilled in the art. Although any method and material similar or equivalent to those described herein may be used in the practice or testing of the embodiments of the present invention, the preferred methods, devices, and materials are described herein.All publications mentioned in this description are incorporated herein by reference in their entirety. Nothing contained herein should be construed as an admission that the invention is not entitled to be prior to this description by virtue of an earlier invention. It should also be noted that, as used herein and in the appended claims, the singular forms a, an, and the include a plural reference unless the context otherwise indicates. Thus, for example, a reference to a combustion chamber is a reference to one or more combustion chambers and their equivalents known to those skilled in the art, and so forth. As used herein, the term approximately means plus or minus 10% of the numerical value of the number with which it is used. Therefore, approximately 50% means within the range of 45%–55%. As used herein, the term sorbent material is intended to encompass all known materials from any source that are capable of absorbing or adsorbing liquids and / or gases. For example, sorbent materials include, but are not limited to, carbonaceous materials such as activated carbon, reactivated carbon, carbon nanotubes, or graphene. Other sorbent materials that are not carbonaceous include natural and synthetic zeolites, silica, silica gel, alumina, zirconia, and diatomaceous earth. In a particular embodiment, the sorbent material is activated carbon. As used herein, the descriptions and claims of multiple sheets of sorbent material mean that there are multiple separate sheets with sides and / or surfaces close to one another. Alternatively, the descriptions and claims of sheets of multiple sorbent materials mean that there is a single sheet that has been rolled or folded upon itself to produce a mass of sheets stacked, rolled, or otherwise constructed with sides and / or surfaces close to one another. The term also contemplates multiple sheets being stacked together and then rolled or otherwise folded, forming alternating layers in a single mass. As used in the context of a sorbent, sorbent material, or sheets of sorbent material, the term surface means the outer boundary of that individual component. Even more specifically, in the context of sheets of sorbent material, the term surface means the larger, flat faces of the sheets, which, when rolled or stacked facing each other or facing themselves, form a surface. In a sheet, the surface is the portion that is significantly larger than the thickness of the sheet. 7! LRLn / ZZnZ / q / Yli The embodiments of the invention relate to devices containing one or more sheets of sorbent material, sheets of sorbent material, methods for manufacturing sheets of sorbent material, and devices containing these sheets. In several embodiments, the sheets of sorbent material may be composed of a sorbent material and a binder and have a thickness of less than approximately 2 mm or less than approximately 1 mm. The devices of several embodiments may include a housing and one or more sheets of sorbent material. In some embodiments, the devices may have an empty fraction of approximately 10% or more of the total volume of the housing. A sheet form of activated carbon with activated carbon contents of approximately 80% to 90% or more by weight can be produced using specific fibrillating binders. Furthermore, the activated carbon is not fouled (i.e., its pores are not blocked and its capacity is not reduced) by such a binder, thus providing significantly higher capacity and faster kinetics compared to traditional papermaking technology. The sheet's flexibility allows for extensive design flexibility, enabling continuous flow designs as well as continuous flow with variable pressure drop and capacity as required. Illustrative sheets are described below.These sheets can be laminated with a variety of other materials that will not clump the sheet together, that will facilitate bonding of the sheet within the collector (e.g., by sonic welding or heat setting) and that will eliminate any concerns about fugitive dust. The Sheets of Absorbent Material The sorbent material sheets of the invention may include any of the sorbent materials described above, including, but not limited to, carbonaceous materials such as activated carbon, carbon nanotubes, or graphene. Other sorbent materials that are not carbonaceous include natural and synthetic zeolites, silica, silica gel, alumina, zirconia, and diatomaceous earth. In one embodiment, the sorbent material sheets include activated carbon. The sorbents may be used alone or in combination. Activated carbon comes in various grades and types, selected based on performance requirements, cost, and other considerations. It can be granular, obtained by re-agglomerating powder; granular, obtained by crushing or grinding nutshells, wood, coal, or granules created by extrusion; or activated carbon in powder form. Activated carbon can be formed through carbonization and activation processes. Raw materials such as wood, nutshells, coal, pitch, coconut, etc., are oxidized and devolatilized, and / or carbon dioxide is gassed and activated with steam to form the porous structure in activated carbon that is useful for adsorption. The initial oxidation and degassing process may include chemical treatment with a dehydrating agent, such as phosphoric acid, sulfuric acid, sodium hydroxide, potassium hydroxide, or combinations thereof. A variety of activation processes are known in the art. The most useful processes for providing activated carbon for the sorbent material sheets of the claimed invention involve a step of providing wood and / or wood by-products, acid-treating the wood and / or wood by-products by exposure to phosphoric acid, and carbonizing the wood and / or wood by-products by using steam gasification and / or 7! LRLn / ZZnZ / q / Yli carbon dioxide. This process results in activated carbon particles that have the highest butane working capacity (BWC), which is a measure of activated carbon performance. Activated carbon can be formed from materials including bagasse, bamboo, coconut husks, peat, hardwoods and softwoods in the form of sawdust and scrap, lignite, synthetic polymers, coal and coal tar, petroleum pitch, asphalt and bitumen, corn stalks and husks, wheat straw, spent grains, rice husks and hulls, nut shells and their combinations. The sheets of sorbent material may also include one or more binders.The forms are not limited to particular binders, which may include polytetrafluoroethylenes (PTFE or Teflon), polyvinylidene fluorides (PVF2 or PVDF), ethylene-propylene-diene rubbers (EPDM), polyethylene oxides (PEO), UV-curable acrylates, UV-curable methacrylates, heat-curable divinyl ethers, polybutylene terephthalate, acetal resin or polyoxymethylene, fluoroelastomers such as perfluoroelastomers (FFKM) and tetrafluoroethylene / propylene rubbers (FEPM), aramid polymers such as para-aramid and meta-aramid polymers, polytrimethylene terephthalate, ethylene acrylic elastomers, polyimide, polyamide-imides, polyurethanes, high-density and low-density polyethylene, polypropylene, biaxially oriented polypropylene (BoPP), polyethylene terephthalate (PET), biaxially oriented polyethylene terephthalate (BoPET), polychloroprene and copolymers and their combinations.The binders can be thermoplastic or thermosetting as required by the conditions, and may include mixtures of thermoplastic and thermosetting compounds. The form of one or more binders includes one or more liquid binders having some associated rheological or viscosity characteristics, elongated fibers that are woven or nonwoven, or particles. In some embodiments, the binder includes multiple of the above physical forms that are mixed so that the resulting mixture is substantially homogeneous. The amount of binder may be from approximately 1% to approximately 40% by weight of the total composition and, in certain embodiments, the amount of binder may be from approximately 1% to approximately 20% by weight or from approximately 2% to approximately 10% by weight, of the total composition, or any individual amount or range encompassing these example amounts.The binder may be present in an amount of approximately 1%, approximately 2%, approximately 3%, approximately 4%, approximately 5%, approximately 6%, approximately 7%, approximately 8%, approximately 9%, approximately 10%, approximately 11%, approximately 12%, approximately 13%, approximately 14%, approximately 15%, approximately 16%, approximately 17%, approximately 18%, approximately 19%, approximately 20%, or any interval composed of two or more of the foregoing amounts, all of which are measured by weight of the total composition. In some embodiments, the sheets of sorbent material may include a solvent, which may generally be present in small residual amounts of, for example, less than 10%, less than 5%, or less than 2% and more than approximately 0.1% or 0.2% by weight. In particular, in some embodiments, the sheets of sorbent material may contain no solvent (0%). 7! LRLn / ZZnZ / q / Yli In some embodiments, the sheets of sorbent material have a thickness of less than 3 mm, less than 2.8 mm, less than 2.6 mm, less than 2.4 mm, less than 2.2 mm, less than 2.0 mm, less than 1.8 mm, less than approximately 1.6 mm, less than approximately 1.4 mm, less than approximately 1.2 mm, less than approximately 1.0 mm, from approximately 0.01 mm to approximately 2 mm, from approximately 0.01 mm to approximately 1.8 mm, from approximately 0.1 mm to approximately 1.6 mm, from approximately 0.01 mm to approximately 1.4 mm, from approximately 0.01 mm to approximately 1.2 mm, from approximately 0.01 mm to approximately 1.0 mm, from approximately 0.02 mm to approximately 0.90 mm, from approximately 0.05 mm to approximately 0.95 mm, from approximately 0.05 mm to approximately 0.90 mm or any individual thickness or interval encompassed by these example intervals. Sheets of sorbent material of various types may have a density of approximately 0.The density of sorbent material sheets can range from 0.05 g / cm³ to approximately 2.0 g / cm³, and in other configurations, sheets of sorbent material may have a density of 0.08 g / cm³ to approximately 1.5 g / cm³, approximately 0.1 g / cm³ to approximately 1.3 g / cm³, or any density or range encompassed by these example ranges. The density is calculated by first measuring the thickness of a given square or circular sheet with a micrometer, multiplying it by the surface area to obtain the volume, and then weighing the piece to obtain the density (weight / volume). The BWC for each sheet of sorbent material may be greater than about 7 g / 100 cm3, and in some embodiments, the BWC may be about 7.0 g / 100 cm3 to about 30 g / 100 cm3, about 8.0 g / 100 cm3 to about 25 g / 100 cm3, about 10 g / 100 cm3 to about 20 g / 100 cm3, about 10 g / 100 cm3 to about 15 g / 100 cm3, about 11 g / 100 cm3 to about 15 g / 100 cm3, about 12 g / 100 cm3 to about 15 g / 100 cm3 or any individual BWC or range covered by these example ranges. In other examples, the BWC may be approximately 9 g / 100 cm3 to approximately 15 g / 100 cm3, approximately 12 g / 100 cm3 to approximately 20 g / 100 cm3, approximately 13 g / 100 cm3 to approximately 20 g / 100 cm3, approximately 14 g / 100 cm3 to approximately 20 g / 100 cm3, or approximately 15 g / 100 cm3 to approximately 20 g / 100 cm3.It is also contemplated that any of the endpoints of the previous intervals can be combined to form new and distinct intervals. As discussed previously, butane working capacity (BWC) is a measure of activated carbon performance. BWC is determined for a sample by measuring the activated carbon's ability to adsorb and desorb butane from dry air under specific conditions. It measures the difference between the butane adsorbed at saturation and the butane retained per unit volume of carbon after a specific purge. BWC can be tested in several ways, including procedures specified by ASTM International and familiar to those skilled in the art. Specifically, testing can follow ASTM D5228, including revisions D5228-16, D5228-92 (2015), D5228-92 (2005), and D5228-92 (2000). It should be noted that, in addition to the BWC test methods described above, further tests may be performed in various configurations. For example, the overall performance of the sorbent or sorbent materials as installed in a vehicle's fuel system is subject to various tests by government agencies, such as the U.S. Environmental Protection Agency (EPA). These tests are not limited to, and include, tests conducted in a SHED test chamber to determine one or more stall losses, running losses, and hot soak losses. Such tests may be conducted in a daytime configuration, for example, to determine stall losses. The sorbent material sheets of the embodiments can be manufactured by any suitable process. In some embodiments, the sorbent material sheets can be manufactured by pulverizing granular or pelletized sorbent material into a powder, mixing the powder with a binder to form a slurry, and optionally heating and rolling the slurry to form the sorbent material sheet. The pulverizing step can produce sorbent particles having an average particle diameter of approximately 0.001 mm to approximately 0.2 mm, approximately 0.005 mm to approximately 0.1 mm, approximately 0.01 mm to approximately 0.075 mm, or any individual particle diameter or range encompassed by these example ranges. In certain embodiments, the pulverized sorbent particles can have an average particle diameter of approximately 0.001 mm to approximately 0.01 mm.The step of mixing the powder with a binder may include mixing the sorbent particle powder with approximately 2% to approximately 20% by weight or approximately 2% to approximately 10% by weight of the total composition, or any individual amount or range encompassed by these example ranges. Heating may be carried out at any temperature sufficient to remove residual solvent, such as, for example, from approximately 50°C to approximately 200°C. The sorbent material sheet of the invention may include several particle size distributions to increase the packing efficiency of the powder within the sorbent material sheets. The selection of different particle sizes can also improve the rheological properties of the powder and surrounding binders, allowing for better mixing and uniform particle distribution before the formation of the sorbent material sheets. In some embodiments, the particles in the sorbent material sheet may have a single particle size distribution, and in other embodiments, the particles may have two different particle size distributions. In further embodiments, the particle may have at least three different particle size distributions. The average particle sizes of at least two different particle populations, each with a particular size distribution, can be selected to have a ratio between approximately 1:1 and approximately 1:15. In other embodiments, the average particle sizes of the two different particle populations can have a ratio of approximately 1:2 to approximately 1:10. The average particle sizes can also have a ratio of approximately 1:2 to approximately 1:5, or combinations of any of the ratios listed above. Sheets of sorbent material can be configured together in a variety of ways depending on the physical space they must fit into, the required device performance, and the features located near the sheets. In some configurations, the sheets may be corrugated, folded, and / or have holes or openings to increase the surface area of ​​the sorbent material exposed to the passing fluid, thereby increasing performance for a given total sheet surface area. The various corrugations, folds, holes, and openings can also be sized and positioned to accommodate internal and external features, such as fluid channels, piping, sensors, and valves. The folds in the sorbent material sheets can take a variety of forms, such as a spiral-wrapped configuration in a cylindrical or elliptical shape.The folds can also be S-shaped, or convex or concave C-shaped, depending on the required dimensions of the device and / or any other necessary internal or external features. The sheets of sorbent material can also be stacked in a flat or curved configuration, and the stacked sheets can be square, rectangular, circular, oval, or other irregular shapes as needed to fit the intended space. This, along with the texture, in combination with the housing characteristics discussed below, allows devices formed from sheets of sorbent material to fit within the confines of vehicle air intakes, air filters, air filter boxes, manifolds, intake ducts, and other parts of a vehicle's air intake system. In addition to the configurations described above, sorbent sheets can also have surface features. In some embodiments, sorbent sheets may include raised portions, and in others, they may include recessed portions. These surface features can be combined within the same sheet. The inclusion of raised and / or recessed portions in the sheets can be used to form various configurations between them as they are stacked, wrapped, and so on. For example, the sheets can be aligned so that the raised and / or recessed portions interlock, bringing adjacent sheets closer together. Alternatively, the sheets can be aligned so that the raised and / or recessed portions do not interlock, creating a gap between adjacent sheets.The alignment can be used to form various open and closed channels for vapor adsorption between the sheets. The performance of carbon sheets can be enhanced by adding materials before or during processing. These materials provide beneficial properties, such as improved porosity or adsorption of inorganic vapors like H₂S or other volatile gases. Alternatively, different sorbent materials can be processed simultaneously on a single sheet, resulting in varying cross-sections or a performance gradient from one side of the sheet to the other. Examples of additives that provide porosity include, but are not limited to, foam-like polymeric additives; water-soluble polymers, which could be rinsed away to leave pores behind; friable materials with a particle size larger than the intended film thickness, which would break down and leave pores; thermally labile materials so that the film can be heated and the added materials vaporized, producing pores in the films; and other similar processes that could impart controlled porosity within sorbent films. Any of these can be used alone or in combination. An alternative improvement to the production of sorbent sheets is to process them in such a way that two or more sorbents with different properties are included in a single sheet but separated along its width. For example, a high BWC sorbent could be used in the same sheet as a low BWC sorbent, so that the vapors from the fuel tank emissions would come into contact with the high BWC sorbent before the low BWC sorbent, within a single chamber. That is, in some embodiments, the low and high BWC sorbents could be homogeneously mixed, or in other embodiments, there could be distinct sections of low or high BWC sorbents as needed. Another example is a high BWC sorbent for butane adsorption, included with a sorbent that would remove H2S or other undesirable vapors that are not normally removed well with a high BWC activated carbon, for example. Product of Absorbent Material Sheet In certain embodiments, the sorbent material sheet (such as Galgon Carbon's CALFLEX) is produced as described above and laminated or otherwise bonded to a backing sheet to form a sorbent material sheet product. The backing sheet is not limited and can be any polymeric material capable of supporting the sorbent material sheet while allowing the overall sorbent material sheet product to be attached to various components in a vehicle's air intake system. The sorbent material sheets described above are combined into a sorbent sheet product. Combining the sorbent material sheets takes advantage of one or more of the characteristics described above, such as a higher surface area-to-volume ratio, reduced void space, improved sorbent performance, etc. Generally, the individual sorbent material sheets are arranged side-by-side to form a sorbent sheet product comprising sheets that are stacked, rolled, wound, folded, and / or laminated such that the surfaces of the sorbent material sheets are very close or adjacent to each other. Regardless of the arrangement, the objective is to maximize the surface area of ​​the sheets exposed to the vapor, fluid, and / or gas stream and, therefore, the performance of the sorbent material sheets. In some forms, the backing sheet is made of polyester, polyethylene, high-density and low-density polyethylene, polypropylene, polytetrafluoroethylene (PTFE or Teflon), polyvinylidene fluorides (PVF2 or PVDF), ethylene-propylene-diene rubbers (EPDM), polyethylene oxides (PEO), UV-curable acrylates, UV-curable methacrylates, heat-curable divinyl ethers, polybutylene terephthalate, acetal resin or polyoxymethylene, fluoroelastomers, perfluoroelastomers (FFKM) and / or tetrafluoroethylene / propylene rubbers (FEPM), aramid polymers, para-aramid polymers, meta-aramid polymers, polytrimethylene terephthalate, ethylene acrylic elastomers, polyimide, polyamide-imides, polyurethanes, biaxially oriented polypropylene (BoPP), polyethylene terephthalate (PET), biaxially oriented polyethylene terephthalate (BoPET), polychloroprene, any hydrocarbon-permeable membrane, and copolymers and combinations thereof.Any of the above materials, which can be woven or non-woven fibers. The reinforcing sheet can have any structure, including an extruded sheet, a non-woven sheet, a woven sheet, a cast sheet, an injection-molded sheet, and combinations thereof. In some embodiments, the backing sheet is made of the same material as the binder of the sorbent sheet. In other embodiments, the reinforcing material is made of a different material than the binder of the sorbent sheet. The structure and methods for bonding the sorbent material sheet to the reinforcing sheet to form the sorbent material sheet product are not particularly limited. In some embodiments, the sorbent material sheet is laminated by passing the sorbent material sheet and the reinforcing sheet through a roller mill. In other embodiments, the sorbent material sheet and the backing sheet are co-extruded from a single extrusion die. In still other embodiments, the sorbent material sheet and the reinforcing sheet are bonded by at least one layer of adhesive or by the surface energy of at least one sorbent material sheet or the reinforcing sheet. In some embodiments, the sorbent material sheet and the reinforcing sheet are bonded to each other by placing a double-sided adhesive substrate between the sorbent material sheet and the reinforcing sheet.In some embodiments, the sorbent material sheets may be edge-sealed to a reinforcing sheet or encapsulated between sheets; in some cases, the membrane is sealed beyond the carbon, meaning the carbon is within a pocket formed by the reinforcing material. In some embodiments, the carbon sheets may be fully or partially laminated, or laminated within the limits of the lamination, i.e., not extending to the edge of the device. In still other embodiments, the sorbent material sheet and the reinforcing sheet are joined by sonic welding or mechanical fasteners including staples, screws, nails, clamps, tabs, or posts. In some embodiments, a reinforcing sheet may be provided on each side of a sorbent material sheet. Similarly, in some embodiments, separate sorbent material sheets may be positioned on either side of a reinforcing sheet.In still other configurations, multiple alternating layers of sorbent material sheets and reinforcing sheets can be used. In some embodiments, the reinforcing sheet is omitted entirely, and the sorbent sheet product can be used directly, either alone or with a clamping reinforcement or adhesive. In one embodiment, the sorbent sheet product comprises a sorbent sheet with an adhesive on one side for direct attachment to an air inlet. In such embodiments, the sorbent sheet product may be provided with a peelable liner to protect the adhesive before application to the air inlet. In several advantageous embodiments of the description, one or more of the sorbent material sheets, the reinforcing sheet, or both include a porous coating layer that may include an edge seal. This coating aids in the production, handling, and installation of the sorbent material sheets or a sorbent material sheet product formed from one or more sorbent material sheets. During the production, handling, and installation of conventional sorbent sheets, sorbent material particles frequently flake off the sheets. These flake particles generate dust, which is undesirable because it can damage equipment, increase the need for cleaning, and pose a respiratory hazard.The porous coating layer, and optionally the associated edge seal, prevents this by providing a region of the sorbent material sheets or sorbent material sheet product where the sheet edges are formed along the periphery so that the sorbent material cannot be dislodged. In some embodiments, one or more edges along the periphery are formed so that no sorbent material is included in the binder, thus ensuring that no material can be released. The exclusion of sorbent material from these regions ensures that during handling and manufacturing of the sorbent material sheet or sorbent material sheet product, the most heavily handled regions do not produce dust.When the edge regions of the sorbent material sheet product do not have sorbent material, this is formed by surrounding the sorbent material sheet with the porous coating layer and then by joining the porous coating layer that extends beyond the edge of the sorbent material, sort of like a bag. The shape of the porous coating layer is not limited, provided it is not damaged by the vapors the sorbent sheet product is expected to encounter (such as hydrocarbon vapors) and is sufficiently porous to allow those vapors to come into contact with the sorbent material within the sheets. The porous coating layer may be a nonwoven layer, a woven layer, a yarn layer, or combinations of one or more of the above. Nonwoven layers include those manufactured by meltblowing, spunbond, flash spinning, air lay-up, wadding, or vibration of an existing sheet, although these are not specifically limited. Alternatively, one or more edges along the periphery still contain sorbent material, but one or more layers of porous coating are bonded together to prevent the sorbent material from detaching. In still more embodiments, one or more additional edge-sealing binders are added to the edge seal to ensure that no sorbent material detaches.The composition of the porous coating layers or additional edge sealing binders is not limited and includes one or more of polytetrafluoroethylenes (PTFE or Teflon), polyvinylidene fluorides (PVF2 or PVDF), ethylene-propylene-diene rubbers (EPDM), polyethylene oxides (PEO), UV-curable acrylates, UV-curable methacrylates, heat-curable divinyl ethers, polybutylene terephthalate, acetal resin or polyoxymethylene, fluoroelastomers such as perfluoroelastomers (FFKM) and tetrafluoroethylene / propylene rubbers (FEPM), aramid polymers such as para-aramid and meta-aramid polymers, polytrimethylene terephthalate, ethylene acrylic elastomers, polyimide, polyamide-imides, polyurethanes, high-density and low-density polyethylene, polypropylene, biaxially oriented polypropylene (BoPP), polyethylene terephthalate (PET), biaxially oriented polyethylene terephthalate (BoPET), polychloroprene and copolymers and their combinations.In some embodiments, the edge-sealing binder is different from the binder present in the rest of the sorbent sheet product. In some embodiments, the edge-sealing binder is the same as the binder present in the rest of the sorbent sheet product. In still other embodiments, the edge-sealing binder is the same as the porous coating layer. In still other embodiments, the edge seal is formed by an additional treatment of one or more edges of the sorbent material sheets or reinforcing sheets, called edge sealing treatment. Edge sealing treatment is not limited to and includes one or more of the following: localized heating by infrared radiation, ultrasonic vibration, or contact with a heated tool; localized curing or crosslinking by ultraviolet radiation or oxidizing or free-radical compounds; localized application of adhesive, binder, tackifier, or primer; mechanical fastening by at least one of the following: stitching, folding, stapling, or clamping; and combinations of the above techniques. However, it can also be seen that in certain embodiments, no edge sealing treatment is performed, and the edge seal is formed by omitting the sorbent material particles from the edge sealing area. The edge seal configuration is not limited. In some embodiments, the edge seal extends around the entire perimeter of the sorbent material without interruption. In other embodiments, the edge seal extends around the entire perimeter but is punctuated by one or more separate adhesive layers, double-sided adhesive tape or substrate, thermal stakes, sonic welding, or mechanical fasteners including staples, screws, nails, clamps, tabs, posts, or holes used to join sheets of sorbent material to other sheets of sorbent material or to another substrate. In still other embodiments, the edge seal does not extend around the entire perimeter and is present only in those regions where handling is anticipated.In additional modalities, the edge seal is present around rows on the inside of the sorbent material sheets that are used to join the sorbent material sheets to other sorbent material sheets or to other substrates. The size of the edge seal is not limited and is measured by how far the edge seal extends inward from one edge of the sorbent sheet to the greater part of the sorbent sheet, or outward from the edge of a device or fitting (e.g., a hole) joining the sorbent sheet to another sorbent sheet or to an external substrate. This size is referred to herein as the edge seal width. The edge seal width may be approximately 1 mm, approximately 2 mm, approximately 2.5 mm, approximately 3 mm, approximately 4 mm, approximately 5 mm, approximately 6 mm, approximately 7 mm, approximately 8 mm, approximately 9 mm, approximately 10 mm, approximately 15 mm, approximately 20 mm, approximately 25 mm, or approximately 30 mm, or any interval consisting of one or more of the above values.In certain embodiments, the edge seal width is approximately 1 mm to approximately 10 mm, or approximately 1 mm to approximately 7 mm, or approximately 1 mm to approximately 5 mm, approximately 2.5 mm to approximately 5 mm, or any combination of one or more of the above ranges. Figures 6 and 7 show an example of the edge seal and edge seal width, where the edge seals, formed by localized heating, are present around the entire perimeter of a sheet of sorbent material and around the holes used to mount the sheet of sorbent material to an external substrate that is an air inlet box surface. In some embodiments, the sorbent film product is rolled. The rolled sorbent film product has a BWC greater than approximately 7 g / 100 cm³. The rolled sorbent film product has a BWC of approximately 7.0 g / 100 cm³ to approximately 30 g / 100 cm³, or greater than approximately 12 g / 100 cm³, or greater than approximately 13 g / 100 cm³, or greater than approximately 14 g / 100 cm³, or greater than approximately 15 g / 100 cm³, or greater than 20 g / 100 cm³. 7!

A rolled sorbent sheet product as described herein has a generally cylindrical shape that is substantially longer than its diameter, although any dimension may be employed, including conical or truncated conical variations, as well as ellipsoids or other shapes.

The rolled sorbent film product has a BWC greater than approximately 7 g / 100 cm³. In some embodiments, the rolled sorbent film product has a BWC of approximately 7.0 g / 100 cm³ to approximately 30 g / 100 cm³. The rolled sorbent film product may also have BWC values ​​that are the same as the previously described non-rolled sorbent film products. Similar to the previous discussion regarding stacked sorbent sheets, rolled or coiled sorbent sheets can incorporate multiple particle size distributions or populations of pelleted or powdered sorbent activated carbon. The same relationships discussed above apply. As mentioned previously, this results in higher yields because it allows for a greater amount of activated carbon to be incorporated into the sheets formed in the rolled sorbent sheet product. As used herein, wound or coiled sorbent sheet products refer to any form of layering of one or more sheets of sorbent material by winding, spiral winding, concentric layering of tubes (of any cross-sectional shape, e.g., round, elliptical, square, triangular, rectangular, etc.), or combinations thereof. For example, a single sheet of sorbent material may be spirally wound along its length to form a cylindrical wound sorbent sheet product. As another example, a plurality of sheets of sorbent material may be stacked and then wound together to form a similar cylindrical shape. Alternatively, several sheets, each forming a cylinder with a slightly different diameter than the next, may be arranged so that they form concentric rings in the cross-section of a cylinder of similar size.Various combinations of these and other arrangements can be used to fill the space within any form of housing or container or air inlet, as described elsewhere in this description. As used in the context of a sheet or sheets of wound or coiled sorbent material, the term substantially parallel means that, in a minuscule and infinitesimally small dimension, the two sheets or portions of the same sheets are equidistant from each other in all directions. However, it is also understood that, in the context of wound or coiled sorbent sheets, especially those that are a single sheet wound spirally around a center or core, this means that the sheets are not exactly equidistant from each other in all facing areas.Furthermore, it is understood that in this context, similar variations in the distance between the sheet or sheets are contemplated due to components such as spacers, sensors, openings, pipes, ports, valves, channels, corrugations, pleats, folds, deformation encountered during manufacturing or operation, deformation due to the shape or pressures applied by or through the external casing or air inlet, different wrapping techniques such as for sealing the periphery of the sheets, etc. Similar to the stacked sheet arrangement, the rolled sorbent sheet product has improved performance over the equivalent volume of activated carbon provided in granule or powder form. The performance improvements of the rolled sorbent sheet product of the invention can be measured as the performance of the product containing a given amount of activated carbon versus the performance of that same amount and grade of activated carbon when supplied in a container as granules or powder. In some embodiments, the rolled sorbent sheet product has a BWC (Best Water Content) that is approximately 3%, approximately 5%, approximately 7%, approximately 9%, approximately 10%, approximately 12%, approximately 14%, and approximately 16% higher than the same amount and grade of activated carbon in a container as granules or powder. Ranges based on these amounts are also considered, such as approximately 5-16% higher, approximately 5-14% higher, approximately 10-14% higher, and so on. The sheets of sorbent material in the sorbent sheet product can be configured as flat, wound into a spiral cylinder, wound into an elliptical shape, wound into an elongated rectangular bar, folded, rolled into an S-shape, formed as concentric cylinders, formed as concentric ellipses, formed as a concentric rectangular bar, or as combinations of these shapes. In some embodiments, the sorbent material sheet product will comprise a single sheet of sorbent material that is rolled or coiled to achieve convenient characteristics including, but not limited to, density, void space, pressure drop, capacity, etc. Stacked Sorb Material Sheet Product: The stacked sorbent material sheet product of the invention comprises two or more sorbent sheets, each of which defines an upper surface and a lower surface, and has a known combined total surface area, wherein each sorbent sheet comprises a sorbent material and a binder; wherein the adjacent sorbent sheets are stacked and arranged so that the adjacent upper and lower surfaces are substantially congruent with each other and aligned to permit fluid flow at least between the adjacent upper and lower surfaces. The performance improvements of the stacked sorbent sheet product of the invention can be measured as the performance of the product containing a given quantity of activated carbon versus the performance of that same quantity and grade of activated carbon when supplied in a container as granules or powder. In some embodiments, the stacked sorbent sheet product has a BWC (Best Water Content) that is approximately 3%, approximately 5%, approximately 7%, approximately 9%, approximately 10%, approximately 12%, approximately 14%, and approximately 16% higher than the same volume and grade of activated carbon in a container as granules or powder. Ranges based on these quantities are also considered, such as performance approximately 5-16% higher, approximately 5-14% higher, approximately 10-14% higher, and so on. Air Inlet The sheet product of sorbent material, as described above in various embodiments, is in some embodiments part of an air intake. As used herein, the term “air intake” means all structures through which air or other oxidizers pass before entering the combustion chamber of an engine. The choice of engine is not particularly limited and includes internal combustion engines that operate using any known liquid fuel, or external combustion engines that operate using any known liquid fuel. In some embodiments, the engine is a gasoline engine found in a car, truck, motorcycle, boat, ship, helicopter, airplane, lawnmower, small displacement device, all-terrain vehicle, snowmobile, snowplow, other gardening equipment, and other small engine devices.In other versions, the engine is a diesel engine that is found. 7 / LRLn / 77n7 / q / Yli in a car, truck, motorcycle, boat, ship, helicopter, or airplane. In still other embodiments, the engine is a gas turbine engine found in a car, truck, motorcycle, boat, ship, helicopter, or airplane. The engine can run on any fuel or combination of fuels, including gasoline, diesel, ethanol, kerosene, natural gas (methane), propane, butane, jet fuel, Jet A, Jet A-1, methanol, vegetable oils, biofuels, biodiesel, biogas, butanol, and combinations thereof. When used in an air inlet, the sorbent sheet captures fuel vapors by contacting the vapors and adsorbing them onto the sheet. After adsorption, the fuel vapors can be desorbed by contacting the sheet with a purge gas. The purge gas is not limited and can include air, nitrogen, oxygen, an oxidizer such as nitrous oxide, water vapor, or any other gas passing over the sheet that may contain additional fuel vapors. The sorbent sheet product can be attached or bonded to the inside or outside of the air inlet using any device. Bonding to the air inlet is not limited to, and includes, adhesive layers, double-sided adhesive tape or substrate, heat stakes, sonic welding, or mechanical fasteners such as staples, screws, nails, clamps, tabs, holes, or posts. The sorbent material sheet product can be placed anywhere within an air intake to absorb or adsorb hydrocarbon vapors that would otherwise escape from the combustion chamber, injectors, carburetor, fuel ports, crankcase, or other engine components. In some embodiments, the sorbent material sheet product is placed inside an air filter box or air filter housing, on or inside an air filter, inside an air intake tube, inside a mass air flow sensor, inside a throttle body, inside an air intake manifold, inside an air intake duct that is connected to a single cylinder or combustion chamber, or inside an air intake duct that is connected to multiple cylinders or combustion chambers.In some embodiments, a single sorbent sheet product is placed within one of the locations described above. In other embodiments, more than one sorbent sheet product is placed in one or more of the locations described above. The stacked sorbent sheet product has a BWC at least 10% higher than the BWC of a pelleted / powdered form of the same amount by volume of sorbent material in the sorbent sheet. The stacked sorbent sheet product has a BWC greater than approximately 7 g / 100 cm³. The stacked sorbent sheet product has a BWC of approximately 7.0 g / 100 cm³ to approximately 30 g / 100 cm³, or greater than approximately 12 g / 100 cm³, or greater than approximately 13 g / 100 cm³, or greater than approximately 14 g / 100 cm³, or greater than approximately 15 g / 100 cm³, or greater than 20 g / 100 cm³. Intervals are also considered, such as about 10-20 g / cm3, about 10-12 g / cm3, about 10-14 g / cm3, about 12-14 g / cm3, about 12-15 g / cm3, and about 15-20 g / cm3. In some embodiments, the stacked sheets are maintained in a separate relationship that controls one or more void volumes, flow regimes, pressure drops, and other characteristics. Such separation is achieved in some embodiments where at least one of the two or more sheets of sorbent material is corrugated. Separation can also be achieved with various folds in the sheets, and also by corresponding raised and / or sunken portions of the sheets that align to form gaps between them. If the sheets are deliberately arranged so that the raised and / or sunken portions do not interlock, this results in further separation between the sheets and allows fluid flow in those portions.If the sheets are deliberately arranged so that at least some raised and / or recessed portions fit between them, this results in a tighter sheet stack and decreases the gap between the sheets, with a corresponding decrease or even interruption of fluid flow. Combinations of these features can be used to form stacked sorbent sheet products with regions or channels directed for fluid flow and edge barriers or seals to prevent fluid leakage. These fluid flow features may also include holes, cuts, or openings through one or more of the sheets in the stacked sorbent sheet product. Each sorbent sheet defines opposite lateral edges that are substantially parallel to the fluid flow. Congruent lateral edges of adjacent sorbent sheets may be separated, joined, or a combination thereof. In this way, the edges of the stacked sorbent sheet product may be sealed, partially sealed, or open. The sealed or unsealed nature can be chosen to achieve desired results, such as modifying the fluid flow regime and / or patterns or other properties. In some embodiments, the product of stacked sorbent material produces an empty volume of approximately 10% or more, approximately 12% or more, approximately 14% or more, approximately 15% or more, approximately 16% or more, approximately 17% or more, approximately 18% or more, approximately 19% or more, approximately 20% or more, approximately 21% or more, approximately 22% or more, approximately 23% or more, approximately 24% or more, approximately 25% or more, approximately 26% or more, approximately 27% or more, approximately 28% or more, approximately 29% or more, or approximately 30% or more, or any interval formed by the combination of the above intervals.In some embodiments, the stacked sorbent material product yields a void volume of approximately 10%, approximately 12%, approximately 14%, approximately 15%, approximately 16%, approximately 17%, approximately 18%, approximately 19%, approximately 20%, approximately 21%, approximately 22%, approximately 23%, approximately 24%, approximately 25%, approximately 26%, approximately 27%, approximately 28%, approximately 29%, or approximately 30%, or any interval formed by a combination of the above intervals. In some embodiments, the stacked sorbent material product yields a void volume of approximately 10-15%, approximately 15-20%, approximately 20-25%, approximately 25-30%, or approximately 30-35%. 7! LRLn / ZZnZ / q / Yli In some forms, each sorbent sheet has a density of approximately 0.08 g / cm3 to approximately 1.5 g / cm3. In some cases, the sheet product of sorbent material comprises at least two populations of sorbent particles, where each of the at least two populations has a different average particle diameter. See the previous description of the bimodal particle size distribution discussed with respect to individual sheets of sorbent material. The same distribution proportions as between sorbent particle populations are considered with respect to the product formed by multiple sheets of sorbent material. In some cases, the particle density of sorbent material achieved by at least two populations is greater than the density achieved by either of the two populations alone.The inclusion of a bimodal particle size distribution can also be used to improve the mechanical properties of the sorbent material sheet product because it makes the polymer sheets much more resistant to shear forces. In some cases, a sheet sorbent material product comprises at least two sheets of sorbent material, each having a defined upper surface and a lower surface having a combined total surface area, and wherein each sheet of sorbent material comprises a sorbent material and a binder, and wherein each sheet of sorbent material is stacked and arranged so that adjacent upper and lower surfaces of the separated sheets are substantially parallel and aligned to allow fluid flow at least between adjacent upper and lower surfaces. The term "substantially parallel," as used in the context of a product made of stacked sorbent sheets, means that the sheets maintain the same distance from each other across their entire area, but with exceptions for various physical characteristics and features. These exceptions, which still fall within the scope of "substantially parallel," include, but are not limited to, differences due to variations in components such as spacers, sensors, openings, piping, ports, valves, channels, corrugations, pleats, folds, warping encountered during manufacturing or operation, deformation from the shape or pressures applied by or through the outer casing or air inlet, different wrapping techniques such as those used to seal the sheet peripheries, and so on. In some embodiments, the sheet product of sorbent material has a BWC value approximately 5%, approximately 10%, approximately 15%, approximately 20%, approximately 25%, approximately 30%, approximately 35%, approximately 40%, approximately 45%, and approximately 50% higher than the BWC of the same volume of sorbent material in granular or powder form. These values ​​can also be combined to form ranges, for example, between 5% and 25% higher. The invention also contemplates that these amounts are the endpoints of the ranges, such as at least approximately 40% higher. Wound / Rolled Sorb Sheet Product: The sorbent sheet product may also be wound or rolled as an alternative to, or in combination with, stacked forms. A wound or rolled sorbent sheet product comprises a sorbent sheet defining an upper surface and a lower surface, and combined, they have a known total surface area, wherein the sorbent sheet comprises a 7 / LRLn / 77n7 / q / Yli sorbent material and a binder where the sorbent sheet is coiled to create layers of adjacent sheets that allow fluid flow around and between layers of adjacent sheets. Additional Options Additional embodiments are also contemplated. In one embodiment, the sorbent material sheet product is a rolled sheet comprising a single sheet of sorbent material. In another embodiment, the sorbent material sheet product is a shredded sheet comprising shredded strips of the sorbent material sheet. In yet another embodiment, the sorbent material sheet product consists of sheets cut from the sorbent material sheet into various shapes. When the sheets are shredded or cut, the x and y dimensions of the sheet are greater than the sheet thickness. In still other forms, the sorbent is not a sheet product but rather consists of strands of binder and sorbent. These strands can be individual, woven, non-woven, or in other shapes, including ropes or threads. These shapes can be achieved by fibrillating the binder with the sorbent to form thin strands that are then combined into other forms. Rolled sheets are typically manufactured by winding the sheets around a solid central cylindrical core. This core is a solid polymer or other material. The core is solid and occupies volume. In other cases, the sheet is wound around an open central core, such as a rigid or semi-rigid tube. In either case, the core does not contribute to the performance of the sorbent device. This application aims to make good use of that central core. Activated carbon sheet is wound around a central adsorbent material, producing a coiled device with additional adsorbent capacity. The core is made of sorbent material or is a structure that serves as a core with an internal volume filled with sorbent material. The advantage of this is that it increases the amount of adsorbent within the device, thereby increasing performance. The core could take the form of an open space, a hollow tube, a perforated hollow tube, or another structure used to define a space containing additional sorbent material. The increased amount of sorbent material should result in even better performance. The core may include not only the sheets described above, but also other forms of sorbent material, such as cut or shredded sheets, strings, threads, and the like. Another improvement concerns enhancing the flow between the spirally wound sheet or sheets. The spiral winding of carbon sheets to form an adsorber was achieved by controlling the tension of the winding process. Because the sheets are flexible and have low tensile strength, this sometimes leads to adsorbers where the separation between the wound sheets is inconsistent, difficult to control, or nonexistent. The use of separators, for example in the form of woven or non-woven fabric, mesh, or other material, or the incorporation of particles into the sheet whose diameter is larger than the sheet thickness, leads to a material with higher tensile strength and a predefined separation between the wound layers. The sheet could also be perforated to overcome the problems with inconsistent winding separation by providing a path between the winding layers that prevents carbon clogging and shunting. 7! LALO / ZZnZ / q / Yli A biplanar spacer can be incorporated into the spiral-wound adsorber during the winding process. A separate biplanar spacer, made of polymer, fabric, metal, carbon fiber, or activated carbon fiber, or combinations thereof, would be wound with the carbon sheet to form the final assembly. The spacer could have varying thicknesses to control the size and pressure drop within the adsorber. The orientation of the spacer could be used to control the fluid flow path, which is not necessarily the shortest distance, thus increasing the contact time with the fluid carbon. This would also increase the tensile strength of the unit. In some cases, the retractor can be a porous, non-woven material. Porous, non-woven materials could be incorporated into the wound structure, allowing for uniform separation with a controlled pressure drop. This would also improve tensile strength. To increase the tensile strength of the carbon sheet, a polymer or fibrous network could be incorporated into the sheet during the roller milling process. The network could have various configurations and thicknesses depending on the desired properties of the final sheet. The goal is to increase the material's tensile strength, enabling more reliable winding for better separation and ease of manufacturing. Some designs achieve similar results by incorporating perforated sheets. Rolled sorbent sheets could be perforated before winding to mitigate imperfections in the winding process and provide alternative paths for fluid flow through the adsorber. Instead of woven or non-woven materials, granular or pelletized activated carbon could be used as separators. Activated carbon or some other rigid granular material, preferably a sorbent, can be added to the carbon sheet before or after grinding to serve as a separator and to enhance adsorption capabilities. Either of these separators could be used with stacked sheets as well as rolled sheets with the same advantages. In either configuration, the separator creates a uniform separation. Textures such as corrugation or other surface features could also be employed to achieve the desired characteristics and flow. In some embodiments, the various components, such as sheets of sorbent material, spacers, woven and / or non-woven materials, perforated or non-perforated sheets, additional sorbent material, and other components, can be wound alternately, sometimes referred to as a jelly roll structure, since the alternating components remain parallel to each other and spiral around a core in repeating bands. This embodiment is most useful for embedding spacers or other pleated, textured, or corrugated components between sorbent sheets to precisely control the spacing between the sheets and, therefore, the pressure drop and performance. In still other embodiments, the components can be nested within one another like tubes and not wound spirally. In further embodiments, the components can be layered as flat sheets or non-cylindrical shapes. 7! LRLn / ZZnZ / q / Yli The figures show various embodiments. Figure 1 shows the improvement of including sorbent within a central core of rolled sorbent sheets. In Figure 1, the rolled sorbent sheet 1 is represented by including sorbent sheet 2, which is wrapped around a central sorbent core 3. In another embodiment, Figure 2 represents a rolled sorbent sheet 1 that includes sorbent sheet 2, again wrapped around the central sorbent core 3. However, the embodiment in Figure 2 further includes a tube 4 or other similar structure surrounding the sorbent 3. The tube 4 may include perforations, slits, openings, or other similar features (not shown) to allow at least some gas or vapor to pass between the sorbent contained in the central core and the sorbent sheet material in the outer portion. In still other embodiments, Figure 3 represents a rolled sheet of sorbent material 1 comprising a sheet of sorbent material 2 and further including a separator 5, which is included to precisely control the separation and, therefore, the pressure drop and other performance characteristics of the rolled sheets. Figure 4 represents an additional embodiment, where the stacked sheet of sorbent material 6 comprises several stacked sheets of sorbent material 2. Between each pair of sheets of sorbent material 2 is a separator 5, which is used to precisely control the separation and, therefore, the pressure drop and other performance characteristics of the stacked sheets. In some cases, the sorbent material sheet product can be applied directly to a surface, for example, an air intake manifold, or it can be selectively cured on the outer sheets to form a durable, cured coating that acts as a backing for the rolled or folded sorbent sheets. Such selective curing can be achieved thermally or with a chemical bath, or by actinic radiation, such as ultraviolet light or electron beam curing. In configurations where the sorbent material sheets omit a housing, they can be contained within the space where capture is required, such as the air intake manifold or associated piping. The sorbent material sheets can be attached to these parts in a variety of ways. In some configurations, the sheets are heat-set in the desired position and location. In others, the sorbent material sheets can be secured using mechanical fasteners such as screws, rivets, or clamps, or they can be attached using an adhesive backing. The adhesive backing can be a single layer of adhesive or a double-sided adhesive tape or film. The adhesive used on the backing can include pressure-sensitive adhesives, UV-cured adhesives, heat-cured adhesives, hot-melt adhesives, and multi-part reactive adhesives.Adhesive compositions include acrylic and (meth)acrylate, acrylate and (meth)acrylate, epoxies in one- and two-part formulations, and urethane. The devices in various embodiments may include a housing and the sorbent material sheets described above. The housing can be any shape and can be configured to purify gases. For example, in some embodiments, the housing can be any shape, such as cuboid, cubic, or cylindrical. The sorbent material sheets can be sized to fit inside the housing and substantially fill a space within the housing through which the gas or liquid passes. In some embodiments, two or more sorbent material sheets can be stacked to substantially fill the housing, and in other embodiments, the sorbent material sheets can be wound to form a spiral-wound sheet or pressed to form a stacked sheet. In some embodiments, the stacked or pressed sheets can be arranged so that the sides of adjacent sheets are substantially contiguous.In other embodiments, the stacked or pressed sheets may be arranged so that adjacent sheets are separated. For example, in certain embodiments, the sheets may be corrugated, with sheets of sorbent material forming a series of parallel ridges and grooves, and in some embodiments, the corrugated sorbent sheets may be separated by flat or textured sorbent sheets. The corrugated sorbent sheets may be arranged within the housing in a stacked or spirally wound / rolled configuration. Figures 7 and 8 depict two illustrative sorbent products that can be fitted within an air inlet box. Referring to Figure 7, a parallelogram-shaped sorbent material sheet product 70 is depicted according to one embodiment. The sorbent material sheet product 70 includes a sorbent material sheet product 71 comprising nonwoven polypropylene fibers and a PTFE binder, and holes 72 for mounting the sheet product 70 in an air inlet box (not shown). An edge seal 73 is present along the perimeter of the sheet product 70 and extends inward from the outer edge of the sheet product 70. Separately, there is also an edge seal 74 extending outward from the outer edge of each hole 72. Referring to Figure 8, a trapezoidal sorbent material sheet product 80 is shown according to one embodiment. The sorbent material sheet product 80 includes a sorbent material sheet product 81 comprising nonwoven polypropylene fibers and a PTFE binder, and holes 82 for mounting the sheet product 80 in an air inlet box (not shown). An edge seal 83 is present along the perimeter of the sheet product 80 and extends inward from the outer edge of the sheet product 80. Separately, there is also an edge seal 84 extending outward from the outer edge of each hole 82. In various configurations, the void fraction can be approximately 30% to 32% lower than the void volume of current devices, and in some configurations, the void fraction can be as low as approximately 10%. For example, devices may have an void fraction of approximately 45% to approximately 10%, approximately 35% to approximately 10%, approximately 25% to approximately 10%, or any individual void fraction or range encompassed by these example ranges. Devices of various configurations may exhibit less flow restriction, such as pressure drop, than devices with granular or pelletized sorbent materials. Therefore, more adsorbent material can be incorporated into such devices without reducing the device's flow rate. Devices of such modalities may have BWCs greater than approximately 4.0 g / 100 cm³, and in some modalities, the devices may have a BWC of approximately 4.0 g / 100 cm³ to approximately 20 g / 100 cm³, 5.0 g / 100 cm³ to approximately 18 g / 100 cm³, approximately 7.0 g / 100 cm³ to approximately 16 g / 100 cm³, or approximately 8.0 g / 100 cm³ to approximately 15 g / 100 cm³, or any individual BWC or range encompassed by these example ranges. The devices may exhibit a pressure drop that is at most equal to that of a conventional packed bed of powders, pellets, or granules of activated carbon or other activated compounds.This feature is advantageous because it ensures that the inventive sorbent material sheet product, whether stacked, rolled, wound, or configured in any other way, still has the same ability to process and transfer vapors and gases as conventional devices, despite the increased sorbent performance. In some embodiments, an air intake manifold with integral vapor adsorption can be provided. Such manifolds comprise a manifold structure and at least one sorbent sheet material product fixed to the inner wall of an air intake manifold. Additional Components The invention may include sensors such as a fuel composition sensor. The fuel composition sensor can be used to detect the mixture of gasoline and ethanol or other fuel contained within the air intake housing and sorbent material. This information can be communicated to the ECU so that the vapors subsequently released to the engine can be used more precisely during combustion. Other sensors include temperature sensors, vapor pressure sensors, oxygen sensors, and the like. The sensors may operate on principles of electrochemical interaction, electronics such as thermocouples, electromechanics, refractive index, infrared spectroscopy, and others, depending on the type of information required by the ECU. The sensors may be included individually or in combination within the air intake housing or, if no housing is specified, within the area containing the sorbent material sheets.The sensors can be included in holes or notches cut into the sheets, or in spaces between the sheets with the sheets wrapped or folded around the sensors. EXAMPLE 1: Air Inlet Test To demonstrate the advantages of hydrocarbon adsorption over prior art products, tests were carried out with butane as follows: Test Configuration: • The airtight box contains an injection port and a port for the butane detection sensor. • The sensor remains inside the box during the test and is zeroed before the test begins. • 1.25 ml of butane is injected into the box using a syringe. • The sample is placed in the box once a level of 1,000 ppm is detected. • The timer starts once the test sample is placed in the box. • Measurements are taken at 5-minute intervals for the first 30 minutes and then every 10 minutes until the end of the test (120 minutes, or until 0 ppm of butane is read). The test setup is illustrated in Figure 5. According to Figure 5, a test apparatus 50 is represented. The test apparatus 50 includes a transparent acrylic box 51, one of whose walls has an opening into which the sensor arm 52 is inserted with appropriate sealing and packing material to ensure that no gas escapes from the transparent acrylic box 51. Inside the transparent acrylic box 51, the sensor arm suspends a butane sensor 53 that detects the level of butane contained within the transparent acrylic box 51. An injection port 56 is also present so that butane or other gases can be added. Samples (not shown) are placed inside the apparatus 50 by opening the door 54 using the handle 55. The sorbent sheets were formed by mixing powdered activated carbon and a PTFE binder. The binder was mixed in at approximately 11% by weight. The powdered activated carbon is available from Galgon Carbon Corporation under the product name “RB” and is a carbon-based activated carbon with a gravimetric iodine value of at least 1,070 mg / g. These sorbent sheets were shown to achieve undetectable levels of butane more rapidly than any other product tested, as shown in the graph below. The results are detailed in Figure 6. EXAMPLE 2: Determination of the Butane Activity of the Activated Carbon Sheet of the Hydrocarbon Adsorber (HCA) Butane Activity (BA) is defined as the percentage of butane adsorbed by a sample of activated carbon when the carbon is saturated with butane under the test method conditions. The BA test can be used as a non-ozone-depleting substitute for the ICC 4 test. A factor is provided to correlate the two tests if conversion from BA to ICC 4 is required. Butane Working Capacity (BWC) is defined as the difference between the butane adsorbed at saturation and the butane retained per unit volume of carbon after a specified purge. This method is modeled after ASTM D5742 and ASTM D5228. A bed of activated carbon of known volume and mass is saturated with butane vapor. The mass adsorbed at saturation is measured and expressed as mass of butane per unit mass of carbon, expressed as a percentage. The carbon bed is then purged under prescribed conditions with dry, hydrocarbon-free air. The mass loss is the butane water content (BWC) and is expressed as mass of butane per unit area of ​​carbon. The test conditions govern the adsorption of butane onto activated carbon. Deviations from the method may result in variable butane values. Test Configuration: • Samples must be cut from an HCA using the 3.5” x 2.5” die-cutting tool. The strips of material cut from the part are placed on an oven-ready tray. They are then oven-dried overnight at 105 °C. • Accurately weigh the dry, empty sample tube to the nearest 0.01 grams and record the tare weight. • Fill the column with the cut carbon strip samples. • Reweigh the filled sample tube to the nearest 0.01 grams; record the weight of the carbon and the sample tube. • Calibrate the Butane Adsorption Apparatus. Adjust the water bath to maintain a temperature of 25 ± 0.2 °C. Regulate the butane flow rate through the carbon bed to 250 ± 5 mL / min. Periodically check the flow rate during sample processing. • Place the filled sample tube in the constant-temperature bath, connect the butane supply line to the tube, and allow the butane to flow downwards through the carbon bed for a minimum of 20 minutes or until saturation is achieved. • Carefully remove the sample tube from the apparatus without disturbing the bed, dry it, and weigh it to the nearest 0.01 grams.0.01 grams • After weighing the tube, place the sample tube back in the constant-temperature water bath and connect the air supply line to the tube. Configure the equipment to provide a downward flow of air through the carbon bed. • The rotameters are set to purge the sample with dry air at a rate of 300 ± 5 ml / min for 40 minutes ± 20 seconds. The weight should be checked and recorded to the nearest 0.01 g every ten minutes during the purge cycle. • After the purge time, turn off the air, disconnect the tubing, install stoppers, remove the sample tube from the water bath, and dry it. • Weigh the tube to the nearest 0.01 g and record the mass. EXAMPLE 3: ABC HCA Air Inlet Box Purge / Butane Test In this test Test Setup for the Butane Adsorption Cycle: • Record the dry mass of the sample before oven drying using the analytical balance and dry in the oven at 105°C for at least 3 hours or overnight. • Select the air inlet box for the test and set it up in a test station. • Turn on the butane and set the flow to 0.442 liters per minute (L / min) using the flow meter • Once the flow rate has been established, connect the butane tubing to the box • Place the pocket balance in the box with a divider in place and leave the box door open • Remove the sample from the oven and record the mass using the analytical balance • Place the sample inside the box on top of the divider • Close and secure the door • Run the test for 90 minutes • Before removing the sample from the box at the end of the test, ensure that a resealable polyethylene bag with its mass recorded is ready • At the end of the 90 minutes, remove the sample from the box and bag it immediately • Record the mass of the sample inside the bag. Subtract the mass of the bag from the total mass to record the final mass after the test. Test Setup for Air Purge Cycle: • Disconnect the butane line from the box of the previous butane adsorption cycle. • Turn on the air valve. • Set the air flow rate to 23.70 L / min. • Connect the air line to the box and use another air line to vent any residual butane out of the box. • Use the butane detection sensor to determine if there is no residual butane before removing the additional air line. • With the flow rate set, remove the butane-laden sample from the polyethylene bag and place it on top of the separator in the box. • Close the box door and secure it. • For the first 30 minutes, remove the sample from the box and place it on the analytical balance every 5 minutes.After the first 30 minutes, repeat the mass recording every 10 minutes until a total test time of 120 minutes is reached. The last mass recording will serve as the final mass after the test. When the test is finished, if you are not preparing for further testing, turn off the balances and shut off any gas flow (butane and air). EXAMPLE 4 Three sets of experimental samples were saturated with butane vapor and then purged to determine the total butane working capacity of the sorbent sheets, the effect of edge sealing at different sizes on the total butane working capacity of the sorbent, and the relative performance of the sorbent sheets compared to conventionally used prior art carbon paper sheets. The test was conducted according to Example 3 above. The test results are shown in Table 1 below and in Figure 9. In Table 1, each row labeled Sample is actually the average value of several test runs, and the actual curves for each individual sample are shown in Figure 9. In each of the tests, the sorbent sheet products were generally the same size, but the depth of the edge sealing varied.The edge seal was around the entire perimeter of the sorbent material sheet product. Sample CCC_RD_0070 had a larger overall sheet size and, therefore, a higher average butane adsorption result than CCC_RD_0068 and CCC_RD_0069. Samples CCC_RD_0068 and CCC_RD_0069 were compared to a commercially available carbon paper of the same size commonly used in air inlet evaporative adsorption applications. The sorbent material sheet products of the three inventive samples were formed from a mixture of powdered activated carbon RB at 89 wt% and a total of 11 wt% of a PTFE binder with nonwoven polypropylene fibers. 7!

With regard to the use of any term in the plural and / or singular in this description, those skilled in the art may translate from plural to singular and / or from singular to plural as appropriate to the context and / or application. Various singular / plural permutations may be expressly stated in this description for the sake of clarity. Those skilled in the art will understand that, in general, the terms used herein, and especially in the appended claims (e.g., the bodies of the appended claims), are generally understood as open terms (e.g., the term "includes" should be interpreted as "includes but is not limited to," the term "have" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). While various compositions, methods, and devices are described in terms of comprising several components or steps (interpreted in the sense of including, among others), the compositions, methods, and devices may also essentially consist of or comprise the various components and steps, and such terminology should be interpreted as essentially defining closed groups of members.It shall also be understood by those within the technique that if a specific number of an introduced claim recitation is intended, that intention shall be explicitly recited in the claim, and in the absence of such recitation, that intention shall not be present. For example, as an aid to understanding, the following appended claims may contain the use of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed as meaning that the introduction of a claim mention by means of the indefinite articles "a" or "an" limits any particular claim containing such introduced claim mention to those modalities containing only one such mention, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (for example, "a" and / or "an" should be construed as "at least one" or "one or more"); the same applies to the use of definite articles to introduce claim recitations. Furthermore, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation must be interpreted as at least the number recited (e.g., the simple recitation of two recitations, without any other modifiers, means at least two recitations, or two or more recitations). Moreover, in those cases where a convention analogous to "at least one of A, B, and C," etc., is used, in general, such a construction is understood to mean that someone experienced in the art would understand the convention (e.g., a system having at least one of A, B, and C would include, but not be limited to, systems having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.).In cases where a convention analogous to "at least one of A, B, or C," etc., is used, such a construction is generally understood in the sense that someone skilled in the art would understand the convention (for example, "a system having at least one of A, B, or C" would include, but not be limited to, systems having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.). Those skilled in the art will further understand that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to include the possibilities of including one of the terms, any one of the terms, or both terms. For example, the phrase "A or B" should be understood to include the possibilities of "A or "B" or "A and B." Furthermore, when the characteristics or aspects of the description are described in terms of Markush groups, experts in the technique will recognize that the description is also described in this way in terms of any individual member or subgroup of members of the Markush group. As a person skilled in the art will understand, for all purposes, including providing a written description, all intervals described herein also encompass all possible subintervals and their combinations. Any enumerated interval can be readily recognized as sufficiently descriptive by allowing the same interval to be divided into at least equal halves, thirds, quarters, fifths, tenths, and so on. As a non-limiting example, each interval discussed herein can easily be divided into a lower third, a middle third, an upper third, and so forth. As a person skilled in the art will also understand, all terms such as "up to," "at least," and the like include the aforementioned number and refer to intervals that can be subsequently divided into subintervals as discussed above.Finally, as someone skilled in the technique will understand, a range includes each individual member. Thus, for example, a group that has 1-3 materials refers to groups that have 1, 2, or 3 materials. Similarly, a group that has 1-5 materials refers to groups that have 1, 2, 3, 4, or 5 materials, and so on.
