[0001] This application claims the benefit of U.S. Application No. 63 / 459,835, filed April 17, 2023, and U.S. Application No. 63 / 634,562, filed April 16, 2024, which are incorporated by reference in their entirety for all purposes hereof. FIELD

[0002] This disclosure generally relates to apparatus, systems and methods relating to sorbent articles. More specifically, the disclosure relates to sorbent items with gaps held together. BACKGROUND

[0003] The increase in carbon dioxide (CO2) levels associated with greenhouse gas emissions has proven harmful to the environment. In recent years, the average level of carbon dioxide in the atmosphere has risen to the highest level observed in the last 800,000 years. The rate of increase of CO2 in the atmosphere is also much higher than the rates of previous decades.

[0004] To limit the impact of climate change, it is not only necessary to reduce CO2 emissions to zero in the near future, but also to achieve negative CO2 emissions, for example, through direct atmospheric CO2 capture (“DAC”). Capturing CO2 directly from the atmosphere is one of several means of mitigating anthropogenic greenhouse gas emissions and presents interesting economic prospects as a non-fossil and location-independent source of CO2 for the commodities market and for the production of synthetic fuels. The specific advantages of atmospheric CO2 capture include: a) DAC can address emissions from distributed sources (e.g., vehicles... land, sea and air), which account for a large portion of global greenhouse gas emissions. Petition 870250093064, dated 10 / 10 / 2025, pp. 220 / 296 2 / 49 greenhouse effect and currently cannot be captured at the emission site in an economically viable way; b) DAC can address legacy emissions and therefore can create truly negative emissions; and c) DAC systems do not need to be fixed to the emission source, but can be location independent and can be located at the site of further CO2 processing or use.

[0085] This disclosure should not be interpreted restrictively. For example, the terminology used in this application should be interpreted broadly in the context of the meaning that those skilled in the art would attribute to such terminology.

[0086] Regarding inaccuracy terminology, the terms “about” and “approximately” may be used interchangeably to refer to a stated measurement that includes the stated measurement and also includes any measurements that are reasonably close to the stated measurement. Measurements that are reasonably close to the stated measurement deviate from the stated measurement by a reasonably small amount, as understood and readily determined by those skilled in the relevant art. Such deviations may be attributed to measurement errors, differences in calibration of measuring equipment and / or manufacturing, human error in reading and / or setting measurements, minor adjustments made to optimize performance and / or structural parameters in view of differences in measurements associated with other components, specific implementation scenarios, imprecise adjustment and / or manipulation of objects by a person or machine and / or the like, for example.If it is determined that the experts in the field... Petition 870250093064, dated 10 / 10 / 2025, pp. 234 / 296 16 / 49 relevant would not easily determine values ​​for differences so reasonably small, the terms “about” and “approximately” can be understood as meaning more or less 10% of the declared value. DESCRIPTION OF VARIOUS MODALITIES

[0087] Those skilled in the art will readily understand that various aspects of the present disclosure can be carried out by any number of methods and apparatus configured to perform the intended functions. It should also be noted that the accompanying drawings mentioned herein are not necessarily drawn to scale, but may be exaggerated to illustrate various aspects of the present disclosure and, in that sense, the drawings should not be interpreted as limiting.

[0088] This disclosure relates to assemblies of sorbent articles, as well as systems incorporating them and methods for forming such assemblies. Although the sorbent article is described below for use in capturing CO2 from an air feed stream, for example, it can be used in other adsorbent methods and applications. These methods include, but are not limited to, adsorption of substances from various inputs, including other gas feed streams (e.g., combustion exhaust) and liquid feed streams (e.g., ocean water). The adsorbed substance is not limited to CO2. Other adsorbed substances may include, but are not limited to, other gas molecules (e.g., N2, CH4, and CO), liquid molecules, and solutes. In certain embodiments, the input may be dilute, containing on the order of parts per million (ppm) of the desired substance.

[0089] FIGURE 11 shows an assembly of a sorbent article as known in the prior art. The sorbent article assembly includes a plurality of fibrous plates (identified as “Plates” in the figure) or mats made of a sorbent polymeric material, wherein the plates are flat and can be positioned in a parallel configuration relative to one another. The plates are separated by gaps which are held together by a plurality of Petition 870250093064, dated 10 / 10 / 2025, pp. 235 / 296 17 / 49 solid points (labeled “Points” in the figure) that can be arranged or fixed to a surface of the plates and have a protrusion extending from a plate surface (labeled “Plate Surface”) to define the spacing between adjacent plates. Each of the gaps defines a gap volume, or a space defined by the gap between two adjacent parts of sorbent polymer, which the solid points occupy. The solid points, as known in the art, are sufficiently rigid to provide structural support to hold the gaps and gap volumes and are fixed to the surface by means of adhesive or glue. In this way, the solid points do not function as sorbent material. In fact, the solid points partially cover the surface of the plates to prevent or inhibit the covered portion of the plate surface from effectively facilitating CO2 adsorption.In some examples, solid spots can additionally or alternatively provide undesirable resistance to CO2 adsorption sites on the plates. Furthermore, in some cases, solid spots can create some degree of flow disruption, which can negatively affect the ability of CO2 to diffuse into the plate material.

[0090] FIGURE 1 illustrates a direct air capture (DAC) system or carbon dioxide sorbent assembly 100 comprising a plurality of separable sheets 102 of sorbent article or sorbent element, which may also be referred to as a sorbent polymer compound (SPC), with a first end 102A and a second end 102B opposite the first end 102A. The first end 102A may be called the “upper end” and the second end 102B may be called the “lower end” if the sheets 102 are arranged substantially vertically relative to a support frame 106. The sheets 102 may be formed to lie substantially flat when placed on a flat surface. Assembly 100 includes at least one span-keeping component 104 that is associated with sheets 102. Assembly 100 can be used to capture CO2 in any suitable environment, such as capturing CO2 from the surrounding air, for example. Petition 870250093064, dated 10 / 10 / 2025, pp. 236 / 296 18 / 49

[0091] Assembly 100 also includes support frame 106 which provides structural support for assembly 100. Sheets 102 are arranged within frame 106 and define a span or span volume “G” with a predetermined distance “D” between two adjacent sheets 102. The span-maintaining component 104 is supported by frame 106 and maintains the predetermined distance D between sheets 102 during the adsorption and desorption processes of a DAC process. The span-maintaining component may also occupy not more than about 30%, not more than about 25%, not more than about 20%, not more than about 10%, not more than about 5%, or not more than about 1%, but at least 0.1% of the span volume G, or any other suitable range or value thereafter, as appropriate.As further disclosed in this document, separable sheets 102 of the sorbent article may be arranged adjacent to each other to define the gap G between adjacent separable sheets 102, where the gap G is maintained uniformly between opposite surfaces of adjacent separable sheets 102 to define a passage extending between adjacent separable sheets 102 from an entrance of the separable sheets 102 to an exit of the separable sheets 102. An inlet can be defined by the location where an inlet flow 904 of gas enters the gaps between the sheets 102, and an outlet can be defined by the location where an outlet flow 906 of gas exits the gaps, as shown in FIGURE 9B, for example, during the operation of the assembly 100. In some examples, the separable sheet(s) 102 and / or the gap holding component(s) 104 may be under tension to maintain the initial position of the separable sheet(s) 102 and the gaps G between them.

[0092] The sheets of the sorbent article, or elements, are structured to adsorb and desorb (or capture and release) molecules such as CO2, such as via DAC. The sheets of the sorbent article may be sufficiently soft and flexible to facilitate their movement during the adsorption and desorption (or capture and release) of molecules. The sheets of sorbent articles may be made using one or more of the following materials: expanded polytetrafluoroethylene (ePTFE), Petition 870250093064, dated 10 / 10 / 2025, pp. 237 / 296 19 / 49 polytetrafluoroethylene (PTFE), expanded polyethylene (ePE), other suitable porous polymer or other material with an appropriate structure. In some examples, the sheets of the absorbent article are made of flexible porous polymer. It will be understood that nonwoven materials, such as nanospun materials, meltblown fibers, spunbonded fibers and porous meltfilms may be among the various other suitable porous polymers.

[0093] The sorbent material used in sheet formation can be a substrate with a surface configured to retain the desired substance (e.g., CO2) from entering the surface through adsorption. The sorbent material can vary depending on which substances are targeted for adsorption. In various embodiments, the sorbent material includes a CO2 adsorbent material which may include, without limitation, an ion exchange resin (e.g., a strongly basic anion exchange resin such as Dowex™ Marathon™, a resin available from Dow Chemical Company), zeolite, activated carbon, alumina, metal-organic frameworks, polyethyleneimine (PEI), or other suitable carbon dioxide adsorbent material such as desiccant, carbon molecular sieve, carbon adsorbent, graphite, activated alumina, molecular sieve, aluminophosphate, silicoaluminophosphate, zeolite adsorbent, ion-exchange zeolite, hydrophilic zeolite, hydrophobic zeolite, modified zeolite, natural zeolites,faujasite, clinoptilolite, mordenite, metal-exchange silicoaluminophosphate, unipolar resin, bipolar resin, aromatic cross-linked polystyrene matrix, brominated aromatic matrix, methacrylic ester copolymer, graphite adsorbent, carbon fiber, carbon nanotube, nanomaterials, metal salt adsorbent, perchlorate, oxalate, alkaline earth metal particle, ETS, CTS, metal oxide, chemisorbent, amine, organometallic reagent, hydrotalcite, silicalite, imidazolate zeolitic framework and metal organic framework (MOF) adsorbent compounds and combinations thereof.

[0094] The sorbent material used in the formation of the sorbent article sheets may be present as a coating, a filler, particles Petition 870250093064, dated 10 / 10 / 2025, pp. 238 / 296 20 / 49 dragged and / or in another suitable form. In some examples, the sheets of the sorbent article may be formed by coating any suitable sheet of material with a sorbent material, such that the sorbent material forms a substantially continuous coating on the surface of the sheets or is otherwise integrated into the sheets of material. Suitable sorbent coatings may be formed using one or more of the appropriate sorbent materials as described above.

[0095] The span maintenance components 104 can achieve distance D using any of the means and configurations disclosed in this document. The span maintenance components 104 can also be associated with sheets 102 in different ways, including, without limitation, fixing, coupling, supporting, or being integrated with sheets 102, as further disclosed in this document.

[0096] In FIGURE 2, the support frame 106 that supports the separable sheets 102 to maintain the span G may include span-maintenance components 104 that extend from the support frame 106 through an inner portion of each separable sheet 102 to maintain an initial position of the separable sheet 102. For example, the span-maintenance components 104 are substantially flat structural members that are configured to be fixed to the frame 106 in order to maintain the sheets 102 in a stretched configuration, as shown by the thick arrows indicating the force “F” being applied in the illustrated directions.For example, the span-maintenance component 104 may be film(s), structure(s) made of filaments, metal sheet(s), polymer sheet(s), metal mesh structure(s), polymer mesh structure(s), fabric(s) or any other suitable configuration that may be substantially thin and flexible but may maintain the stretched configuration while being supported by the frame 106.

[0097] In some examples, the span maintenance component 104 includes a first surface 200 and a second surface 202. At least one of the first surface 200 or the second surface 202 may have Petition 870250093064, dated 10 / 10 / 2025, pp. 239 / 296 21 / 49 one of the sheets 102 fixed to it. That is, in some examples, one sheet 102 may be fixed to the first surface 200, while another sheet 102 may be fixed to the second surface 202, thus interleaving the span maintenance component 104 on both sides, so that the span maintenance component 104 is disposed between two sheets 102. In some examples, there may be only one sheet 102 fixed to a surface, the first surface 200 or the second surface 202, but not both. In some examples, several sheets 102 may be fixed to the first surface 200 and / or the second surface 202, so that there is no limitation of only one sheet 102 fixed to a surface. The various sheets 102 may overlap each other when fixed to their respective surface.In some examples, the thickness of the span maintenance component 104 may be from about 25 µm to about 50 µm, from about 50 µm to about 0.1 mm, from about 0.1 mm to about 0.2 mm, from about 0.2 mm to about 0.5 mm, or any other suitable value or range among themselves or combinations of ranges. Beneficially, this configuration allows the fixing of the 102 sheets reducing the number or amount of material used in the “spacers” to maintain the span distance D between them, as well as allowing the non-functional thermal mass to be placed in the center of the 102 sheets, which does not need to be heated, further generating a reduction in thermal mass.

[0098] In FIGURES 3A and 3B, the support frame 106 that supports the separable sheets 102 to maintain the gap G may include one or more gap-maintenance components 104 that extend from the support frame 106 along at least one separable sheet 102 to maintain an initial position of the separable sheet 102. For example, the gap-maintenance component 104 is an elastomer component disposed in the sheet. The elastomer component may be any suitable elastomeric polymer including, without limitation, thermoset polymers and thermoplastic polymers. The elastomer component may be applied to the surface of the sheet 102 as a coating and / or integrated into the sheet material 102, by Petition 870250093064, dated 10 / 10 / 2025, pages 240 / 296 22 / 49 example, by means of filling an interconnected network of the material that forms sheet 102. For example, in FIGURE 3A, the elastomer or gap-holding component 104 is applied to sheet 102 in a portion 300 of sheet 102 whose length is shortened.

[0099] The reduced length portion 300 can be formed by corrugating or crumpling the appropriate portion of sheet 102 to have a shortened length and then applying the span holding component 104 to the corrugated or crumpled portion to maintain the corrugated or crumpled state in such portion, thus forming the reduced length portion 300 whose standard length can be a first length “L1”, as shown in FIGURE 3A, but can be elongated, stretched or extended uniaxially or biaxially to a greater length, as a second length “L2”, as shown in FIGURE 3B, when a force F is applied in the direction shown by the thick arrow.

[0100] In some examples, corrugation or creasing in the reduced length portion 300 can be formed using any suitable method for forming a structured or compacted material, as known in the art, such as those disclosed in U.S. Patent No. 11,097,527 (WL Gore & Associates GmbH), for example. For example, a rotating elastic conveyor belt can be attached to two rotating elements that induce and release elongation transverse to the silicone substrate along a circular motion. The sheet 102 can be applied by means of a pressure roller to the stretched elastic conveyor belt. The sheet 102 moves on the stretched elastic conveyor belt and a structured or compacted sheet 102 is formed during the relaxation of the elastic conveyor belt.Subsequently, a support material can be preheated with an infrared heater, for example, and applied by means of a pressure roller to the structured or compacted sheet 102 at a predetermined location to form a composite comprising a structured or compacted sheet 102 and the support material. The support material can be the elastomer or the... Petition 870250093064, dated 10 / 10 / 2025, pp. 241 / 296 23 / 49 span maintenance component 104 which, when applied to the predetermined location, forms the reduced length portion 300. Other methods, as disclosed in U.S. Patent No. 11,097,527 mentioned above, may be implemented to form the corrugation or dent in the reduced length portion 300, as appropriate.

[0101] In this way, the application of the elastomer component allows sheet 102, or more specifically portion 300 of sheet 102, to assume a reduced configuration (i.e., L1) and an elongated configuration (i.e., L2) without substantially or permanently deforming or breaking sheet 102, thus beneficially compensating for the gap and allowing contraction between cycles of the adsorption and desorption processes. In some examples, there may be additional intermediate configurations spanning the lengths between L1 and L2, so that sheet 102 can assume any intermediate configuration, i.e., any configuration in which portion 300 assumes a length greater than L1 and less than L2 without reaching the minimum or maximum length that portion 300 can assume.In some examples, the elastomer component can be used as an adhesive to fix one end (e.g., 102A or 102B) of sheet 102 to frame 106 so that force F is applied relative to frame 106.

[0102] In some examples, the change from one configuration to another, i.e., from L1 to L2 and from L2 to L1 of portion 300, may be in response to the expansion or contraction of a material that forms the sheets 102. In some examples, the expansion and contraction may depend on the state of the water content or humidity of the environment or within the system or assembly 100, or the lack thereof. That is, in some examples, the dryness of the environment may cause contraction, and humidity may cause expansion. In some examples, contraction and expansion may occur during the adsorption and desorption processes of the DAC event, and although the length of portion 300 may change, the gap distance D between neighboring sheets 102 or the neighboring portion 300 of sheets 102 remains substantially the same. Petition 870250093064, dated 10 / 10 / 2025, pp. 242 / 296 24 / 49

[0103] In FIGURES 4A and 4B, the support frame 106 that supports the separable sheets 102 to maintain the span G may include span-maintenance component(s) 104 that extend from the support frame 106 along at least one separable sheet 102 to maintain an initial position of the separable sheet 102. For example, the span-maintenance components 104 are a plurality of elongated members fixed to the frame 106 in a stretched configuration, such that the elongated members provide support for the sheets 102 that are to be inserted into the space between the neighboring elongated members. In other words, the span-maintenance components 104 may be kept stretched to maintain the spaces in response to the frame 106 applying a constant force F in the directions shown by the thick arrows. With the spaces maintained, the distance of the opening D also remains constant so that the sheets 102 are kept in their predetermined positions within the frame 106.

[0104] In some examples, the span-maintenance components 104 may form a pattern, such as a crisscross pattern, as shown in the figures, such that each of the sheets 102 is arranged between two neighboring span-maintenance components 104, for example, between a first span-maintenance component extending in one direction and a second span-maintenance component extending in another direction separate from the first span-maintenance component. In some examples, the span-maintenance components 104 may be selected from one or more of the following: yarns, fibers, or filaments, or any suitable material and size, as appropriate. For example, yarns may be preferable for a larger structure using thicker sheets 102, and filaments may be preferable for a smaller structure using thinner sheets 102, as determined by the use of the carbon dioxide sorbent assembly 100 or the DAC system implementing it.In some examples, there may be only a single 104 span maintenance component that extends forward and backward in an intersecting configuration between the upper portion and the... Petition 870250093064, dated 10 / 10 / 2025, pp. 243 / 296 25 / 49 lower portion of frame 106, so that a single wire or filament can be used to support all sheets 102. In some examples, the pattern may be any other suitable pattern, including, without limitation, honeycomb, lattice, sinusoidal, polygonal, etc. In some examples, there may not be a distinct pattern, but the span-maintaining components 104 are arranged and arranged in a non-standard or random fashion. These configurations beneficially provide a low-mass means of providing structural support for the sheets 102, as well as having a low or zero surface area impact.

[0105] FIGURES 5A to 5H illustrate embodiments of forming the sorbent article assembly 100, in which the gap-maintaining components 104 include elongated fibers or fibrous components that are passed through the sheets 102 in a predetermined pass-through pattern. In one embodiment, there may be fibers 104A being passed or woven through the sheets 102 to provide support, as shown in FIGURES 5A to 5E. In another embodiment, there may be additional fibers 104B being passed or woven through the sheets 102 to provide additional support, as shown in FIGURES 5F to 5H.

[0106] In FIGURE 5A, the sheets 102 are prepared so that they are arranged in a stacked orientation or in an adjacent side-by-side configuration. Although only five (5) sheets 102 are shown (labeled “a”, “b”, “c”, “d”, and “e” in FIGURE 5A), it should be understood that any suitable number of sheets 102 may be used. In the figure, a plurality of fibers 104A are passed or woven through all the sheets 102 at various locations. In some examples, the pass-through locations may be equidistant from each other.

[0107] In FIGURE 5B, a portion of the sheets 102 is moved or offset in an axial direction shown by the arrows relative to the remaining sheets 102 to create a W-shaped thread passage pattern. For example, this can be achieved by holding “a”, “c”, and “e” of the sheets. Petition 870250093064, dated 10 / 10 / 2025, pp. 244 / 296 26 / 49 102 in place while moving or sliding “b” and “d” of sheets 102 downwards relative to “a”, “c”, and “e” of sheets 102. The same result can be obtained by holding “b” and “d” of sheets 102 in place and moving or sliding “a”, “c”, and “e” of sheets 102 upwards relative to “b” and “d” of sheets 102.

[0108] In FIGURE 5C, external tensioning forces F are applied in the directions indicated by the thick arrows to separate the sheets 102 so that they are no longer in contact with each other and form a span volume G with a span distance D, as shown. In FIGURES 5D, the ends 102A and 102B of the sheets 102 are in contact with an internal surface 500 of the support frame 106 to maintain the span distance D. In such embodiments, the sheets 102 may have sufficient rigidity so that the force against the internal surface 500 is sufficient to support the sheets 102. In some examples, the frame 106 may also have individual grooves (not shown) to receive the rigid sheets 102, so that the sheets 102 can be coupled to the frame 106 without the use of any adhesive or fastener.

[0109] In some examples, the ends 102A and 102B of sheets 102 can be coupled to frame 106 to hold the sheets 102 in the stretched configuration. The coupling can be achieved using fasteners or adhesive 502, as shown in FIGURE 5E, for example, or any other suitable means, as appropriate. In some examples, the fasteners or adhesive 502 can be applied to fix some of the ends 102A and 102B (such as the upper ends 102A of “a”, “c”, and “e” of sheets 102 and the lower ends 102B of “b” and “d” of sheets 102) to frame 106, so that one in every two sheets 102 is fixed and immobilized with respect to frame 106, as shown.

[0110] In FIGURE 5F, which directly follows the configuration shown in FIGURE 5B, after the W-shaped pattern is obtained by the first fibers 104A, the second fibers 104B can be passed or woven through the sheets 102, as shown, where the lower portion of the W-shaped pattern of the first fibers 104A is close to the second fibers 104B. Petition 870250093064, dated 10 / 10 / 2025, pages 245 / 296 27 / 49

[0111] In FIGURE 5G, “a”, “c”, and “e” of sheets 102 are moved or displaced in an axial direction indicated by the arrows relative to “b” and “d” of sheets 102, which remain in place. Alternatively, “a”, “c”, and “e” of sheets 102 can be held in place while “b” and “d” of sheets 102 can be moved or displaced in an axial direction opposite to the arrows shown in the figure, to obtain the same result. As a result, fibers 104B can form an M-shaped pattern that is substantially symmetrical to the W-shaped pattern of fibers 104A. Therefore, fibers 104A can be passed in a first pass pattern, and fibers 104B can be passed in a second pass pattern that is substantially symmetrical to the first pass pattern.

[0112] In FIGURE 5H, external tensioning forces F are applied in the directions indicated by the thick arrows to separate the sheets 102 so that they are no longer in contact with each other and form a span volume G with a span distance D, as shown. In some examples, the sheets 102 may be arranged in the frame 106 so that there is a gap or space between the ends 102A and 102B of the sheets 102 and the inner surface 500 of the frame 106, thus not being in direct contact with the frame 106. These configurations advantageously allow the tension in the passed fibers to seek equalization and align the sheets 102 while separating them, providing a low-mass means to provide structural support for the sheets 102.

[0113] In summary, assembly 100, as shown in FIGURES 5A to 5H, can be formed or manufactured using the following process: align sheets 102 adjacent to each other so that sheets 102 include a first set of sheets (e.g., a, cee in FIGURES 5A to 5H) and a second set of sheets (e.g., bed in FIGURES 5A to 5H); pass fibers 104A through sheets 102; axially displace the first set of sheets 102 relative to the second set of sheets 102, as shown in FIGURE 5B; apply an external tensioning force F to Petition 870250093064, dated 10 / 10 / 2025, pages 246 / 296 28 / 49 ends of fibers 104A, as shown in FIGURE 5C, to form a gap volume G with a predetermined gap distance D between each adjacent pair of sheets 102; and fix the ends of fibers 104A to the frame 106 to maintain the gap distance D formed between sheets 102 during the adsorption and desorption processes.

[0114] In some examples, the process also includes arranging the sheets 102 within the frame 106 so that the ends 102A and 102B of the separable sheets are in contact or coupled to the inner surface 500 of the frame 106, maintaining the external tension force F at the ends of the fibers 104A, as shown in FIGURE 5D. In some examples, the process also includes arranging the adhesive or fastener 502 between some of the sheets 102 and the inner surface 500 of the frame 106 to immobilize the end 102A or 102B of some of the sheets 102 in relation to the inner surface 500 of the frame 106.

[0115] In some examples, the process alternatively includes passing the second set of fibers 104B through the sheets 102, as shown in FIGURE 5F, and axially displacing the second set of separable sheets 102 relative to the first set of separable sheets 102, as shown in FIGURE 5G, so that the external tensioning force F is applied to the first and second sets of fibers 104A and 104B, and the ends of the first and second sets of fibers 104A and 104B are fixed to the frame 106 to maintain the span distance D, as shown in FIGURE 5H. In some examples, the first and second sets of fibers 104A and 104B are passed through the sheets 102 so as to be substantially symmetrical to each other.

[0116] As shown in FIGURES 5C and 5H, the support frame 106 that supports the separable leaves 102 to maintain the span G may include span-maintenance components 104 that extend from the support frame 106 through the adjacent separable leaves 102 to maintain an initial position of the separable leaf 102. The components of Petition 870250093064, dated 10 / 10 / 2025, pp. 247 / 296 29 / 49 span maintenance 104 may also have internal portions 504 (or 504A and 504B in FIGURE 5H) that pass through adjacent separable sheets 102 and clearance portions 506 (or 506A and 506B in FIGURE 5H) disposed between adjacent separable sheets 102.

[0117] In FIGURES 6A-B, 7A-B, 8 and 9A-E, the support frame 106 that supports the separable leaves 102 to maintain the span G may include span-maintenance components 104 that extend from the support frame 106 through an inner portion of each separable leaf 102 to maintain an initial position of the separable leaf 102. Examples of such configurations are disclosed in this document. In FIGURE 6A, the span-maintenance component 104 is an elongated member with a plurality of enlarged members 600 attached to it, such that the elongated member or span-maintenance component 104 is configured to pierce each of the sheets 102, and each of the enlarged members 600 is attached to one of the sheets 102. In some examples, the enlarged members or span-maintenance components 104 may be self-expanding plugs. In some examples, such plugs may be made of foam or any suitable self-expanding polymer, such as self-expanding elastomer.In some examples, the span-maintenance component 104 may include a plurality of sealing members 602 configured to seal openings formed by the elongated member or span-maintenance component 104 piercing the sheets 102. For example, the sealing members 602 may be any suitable polymer, including, without limitation, elastomeric polymers, including, without limitation, thermosetting polymers and thermoplastic polymers.

[0118] In FIGURE 6B, the span-maintenance component 104 is an elongated member, and the sheets 102 have a plurality of self-sealing locations 604 to maintain sheet integrity where the sheets 102 engage with the elongated member or span-maintenance component 104. The self-sealing locations 604 may be determined by or include components Petition 870250093064, dated 10 / 10 / 2025, pp. 248 / 296 30 / 49 polymeric components arranged on one surface of sheets 102 to secure the elongated member or span-maintenance component 104 to sheets 102. The polymeric components may be arranged on one surface or on both surfaces of sheets 102. The polymeric components may be made of the same material or of a material similar to the sealing members 602, and the polymeric components and the sealing members 602 may be arranged on one surface of sheets 102 or extend through the thickness of sheets 102, as suitable.

[0119] In FIGURE 7, the span-holding component 104 is an elongated member with a plurality of beads or enlarged portions 700, or alternatively a string of beads. The elongated member or span-holding component 104 perforates each of the sheets 102, the plurality of sealing members 602 fixed to the sheets 102 assist in sealing the openings formed by the elongated member or span-holding component 104 perforating the sheets 102. In some examples, the beads 700 may be protrusions, raised portions or enlarged portions of the elongated member that are integral to the elongated member (for example, the elongated member being a flexible, rope-like component that forms a plurality of nodes, in which case the nodes may be considered such protrusions).

[0120] FIGURE 7B shows an example in which the gap-holding component 104 includes sealing members 602 that are formed as a plurality of points 602 made of an adhesive polymer arranged across sheets 102 such that a portion of the adhesive points 602 projects outward from the sheets 102. The sheets 102 include through holes, openings, or holes that pierce the sheet 102 so that the adhesive forming the adhesive point 602 has the ability to penetrate through the sheet 102 before hardening to become the adhesive point 602. Hardening of the adhesive may be facilitated by drying or curing using any suitable means as disclosed herein. The points 602 may Petition 870250093064, dated 10 / 10 / 2025, pp. 249 / 296 31 / 49 being formed by applying the polymer (in a malleable or viscous state) to a surface until the polymer penetrates through the hole to reach the other surface. After drying or cooling (or application of any other suitable curing methods), the polymer hardens or solidifies to form 602 dots, which have a cross-sectional shape resembling the letter “H”, where the entirety of each 602 dot is made of a single continuous material.

[0121] The adhesive points 602 that penetrate through the sheet 102 also include a through hole or bore 702 that provides a passage for the span holding component 104 to pass through them, and the span holding component 104 may have one or more stoppers (such as the enlarged beads or portions 700, or alternatively, the enlarged members 600) with a cross distance that is greater than the diameter or cross distance of the through hole 702, thus preventing the stop 700 from passing completely through the through hole 702. Beneficially, the adhesive points 602 provide additional weight so that the sheets 102 are held in a substantially straight configuration, as well as to reduce the likelihood of neighboring sheets 102 coming into direct contact with each other.Since the adhesive dots 602 extend throughout the thickness of the sheets 102, the dots 602 are also less likely to detach from the sheets 102 compared to examples where the adhesive is applied only to one surface of the sheets 102, which increases the likelihood of the adhesive detaching from the surface of the sheets 102, for example, due to the hydrophobic nature of the sheet 102 material.

[0122] In FIGURE 8, the gap-keeping component 104 is a filament with a plurality of stitched portions 800, such that each of the stitched portions attaches the filament or gap-keeping component 104 to one of the sheets 102. In some examples, the self-sealing locations 604 may be determined by or include polymeric components arranged on a surface of the sheets 102 to attach the stitched portion 800 of the fiber or gap-keeping component 104 to the sheets 102. Petition 870250093064, dated 10 / 10 / 2025, pp. 250 / 296 32 / 49 In FIGURES 7 and 8, the polymeric components or sealing members 602 may be arranged on the surface of the sheets 102 or extend through the thickness of the sheets 102, as appropriate. In some examples, the elongated members may be flexible materials, such as sutures, which may not provide structural support on their own, while additional components, such as the enlarged members 600, the sealing members 602, the self-sealing locations 604, the beads or protrusions 700, and / or the stitched portions 800, as disclosed herein, may control the locations along the elongated members where the sheets 102 may be arranged during installation. In this way, the configurations of FIGURES 6A, 6B, 7, and 8 beneficially provide a low-mass means of providing structural support for the sheets 102 without relying on additional spacers to maintain the span distance D.

[0123] In FIGURE 9A, the span holding components 104 include a plurality of solid frames, and each of the sheets 102 is supported by one of the solid frames. In the figure, a single solid frame or span holding component 104 is shown, with a sheet 102 that is formed in a tubular configuration arranged around the frame (e.g., by stretching the tubular sheet 102 to fit the sides or “tension ribs” of the solid frame), so that the frame applies forces F to the tubular sheet 102 in the directions shown by the thick arrows. In some examples, instead of the tubular configuration, two separate sheets 102 may be fixed or adhered to the two opposite sides of the frame so as to cover both sides of the frame with sheets 102. In some examples, more than two sheets may be fixed, as appropriate.

[0124] FIGURES 9B and 9C show a DAC assembly with multiple frames or a sorbent article assembly 100 which is formed by arranging a plurality of frames or span holding components 104 side by side in a row, where each span holding component 104 has sheet 102 (or sheets) applied to it in order to form a Petition 870250093064, dated 10 / 10 / 2025, pp. 251 / 296 33 / 49 complete structure with multiple frames. The individual frames can be fixed, fastened, affixed or coupled to each other using any suitable means. The top or side surface of the assembly 100 can define a single consolidated surface for the reactor interface (i.e., an interface for a DAC reactor).

[0125] FIGURES 9D and 9E show the configuration of the sheets 102 during the adsorption and desorption processes, as implemented in the multi-frame structures. Although only three (3) frames are shown, it should be understood that any suitable number of frames can be implemented, and each frame should be considered a separate span-maintenance component 104 that can be removable or replaceable as needed. As shown in FIGURE 9D, each of the frames or span-maintenance components 104 may include an opening 900 that directs air or gas into and out of an internal volume 902 that is defined by the sheets 102 when supported by the frame or span-maintenance component 104.

[0126] In these examples, the span distance D is determined not by sheets 102, but rather by the center lines (C—C) of the individual frames or span maintenance components 104.That is, the span distance D is the distance between two neighboring centerlines C—C of the adjacent frames or span-maintaining components 104, so that the span distance D is maintained even when the sheets 102 move to create a smaller internal volume 902 (a restricted configuration) as shown in FIGURE 9D during the adsorption process showing the two sheets (or two portions of the tubular construction) assuming a concave configuration (e.g., one portion of them flexes inward toward the centerline C—C) to conform to the frame shape, and as the sheets 102 move to create a larger internal volume 902 (an expanded configuration) as shown in FIGURE 9E during the desorption process showing vapor, gas, or air flowing into the internal volume 902 through the openings 900 (passage of. Petition 870250093064, dated 10 / 10 / 2025, pp. 252 / 296 34 / 49 steam, gas or air) in the frames or span maintenance components 104, causing the sheets to assume a convex configuration (for example, a portion of them flexes outward from the C—C centerline).

[0127] These configurations, as shown in FIGURES 9A to 9E, beneficially provide a modular collector design using the multi-frame sorbent article assembly 100, where the tensioning force F is used to provide structure for the sheets 102. The tensioning force F can reduce the number of spacers needed to maintain the span distance D, thus increasing the effective surface area for adsorption and can allow the use of thinner sheets 102 for the assembly 100, which can also potentially increase the effective surface area while improving the pressure drop during operation.

[0128] FIGURES 10A to 10C show examples of the assembly of the absorbent article 100 with a sheet of absorbent material 102 (only one sheet is shown for simplicity, but it should be understood that there may be a plurality of sheets for each assembly) being suspended vertically from a frame component 1002 of the support frame 106. For example, the sheet of absorbent material 102 has a span-maintaining component(s) 104, where each span-maintaining component 104 may include a rigid member 1000 with a predetermined thickness, as well as tabs 1006 extending from each side of the rigid member 1000 that rest on and are supported by the frame component 1002 of the support frame 106 to maintain an initial position of the separable sheet 102 hanging from the support frame 106. FIGURE 10C shows an example in which several sheets 102 sheets of sorbent material are positioned side by side, with each sheet having its own separate rigid member 1000.The rigid members 1000 come into contact with each other to maintain the gap G between the sheets 102 at a predetermined distance D. The distance D of the gap G can be determined by the thickness “T” of the rigid member 1000. Petition 870250093064, dated 10 / 10 / 2025, pp. 253 / 296 35 / 49

[0129] In some examples, the rigid member 1000 may be fixed or adhered to a surface on the upper portion of the sheet 102 to maintain the span G. In some examples, the rigid member 1000 may be coupled to or encircle the upper portion of the sheet 102. Furthermore, in some examples, the tabs 1006 may have any suitable shape or configuration, including, without limitation: a rectangular shape (which is shown in FIGURE 10C), a circular shape, a hook shape, or a key shape, such as those resembling the tabs used on hanging file folders in a filing cabinet. In some examples, the rigid member 1000 and the tabs 1006 may be separate components that are combined or fixed together, or the rigid member 1000 and the tabs 1006 may be made of a single material or unitary component.This configuration includes the benefit of providing tension to the 102 sheets without providing clearance, and therefore the free end of the 102 sheets is not affected by potential tolerance issues, as well as the open end (lower end 102B) of the 102 sheets having the ability to provide damped spacing as well as assisting in fluid drainage from within the 102 sheets.

[0130] As shown, a sheet 102 rests and is suspended from the frame component 1002, pulled downward by the force F of gravity. In some examples, as shown, at least a portion of the sheets 102 may include rigid members 1000, and a frame component 1002 is also provided such that the rigid members 1000, or more specifically the tabs 1006 of the rigid members 1000, are supported by the frame component 1002 of the frame 106. The rigid members 1000 may be fixed at the upper end 102A of the sheets 102 and the tabs 1006 may extend outwards by a predetermined length to be supported on both sides by the frame component 1002, which may be substantially rectangular and may act as a handrail on which the tabs 1006 may rest. In some examples, sheets 102 may also include weighted members or portions 1004 attached to or integrated into sheets 102 at the lower end 102B. Weighted members or portions 1004 Petition 870250093064, dated 10 / 10 / 2025, pp. 254 / 296 36 / 49 provide additional weight to sheets 102 to increase gravitational force or to provide additional gravitational force applied to sheets 102, causing sheets 102 to remain substantially straight during operation, i.e., the adsorption and desorption processes. In either of the above-mentioned examples, during the adsorption and desorption processes, sheets 102 may be arranged in a substantially horizontal alignment or, alternatively, in a substantially vertical alignment, as appropriate.

[0131] The disclosure of this application has been described above both generically and in relation to specific embodiments. It will be evident to those skilled in the art that various combinations, modifications and variations can be made of the embodiments without departing from the scope of the disclosure. Therefore, it is intended that the embodiments encompass the combination, modifications and variations of this disclosure, provided they are within the scope of the appended claims and their equivalents.

[0141] As used in this document, “receiving” information should be understood as an act of “receiving” that requires only one party (or entity, device, etc.) to perform, such that a separate party to perform the act of “sending” is not required.

[0142] As used in this document, “initiating” a separation (or a separation method) should be understood as an act of “starting” that includes an initial or completed act of preparing or dispatching instructions to another party or device with the intention that there be an execution or commencement of a separation process or the association of a separation process already begun with the initiation step. For example, the act of “initiating” the separation of gaseous CO2 may cause a carbon capture device to subsequently receive an instruction, directly or indirectly (e.g., through intermediate entities or devices) to start the separation, in response to which the carbon capture device operates appropriately.In another example, the act of “initiating” a separation (or a separation method) of gaseous CO2 may involve a carbon dioxide removal service provider associating carbon dioxide that has already been removed from the atmosphere (or is currently in an active removal process) with a subsequent initiation of a separation. It will be understood that the instruction received by the carbon capture device need not be provided as part of such an “initiation” operation. Additionally, the act of “separating” the CO2, for example, is not necessarily part of the act of “initiating” such separation, as when the “initiation” of the separation is performed by a first party and the subsequent party. Petition 870250093064, dated 10 / 10 / 2025, pp. 263 / 296 45 / 49 “separation” itself is performed by a second party different from the first party. Furthermore, the act of “separation” need not be performed or fully completed by either the first or second party. It will also be understood that the act of initiation may be fully performed in one jurisdiction or country, even if recognition of the initiation or of a subsequent act or act associated with the initiation occurs in a different jurisdiction or country.

[0143] As used in this document, “initiating” a report (e.g., of data) should be understood as an act of “beginning” that includes the initial or complete act of preparing or sending instructions to another party to prepare, begin, or subsequently complete the report. The act of “reporting” any data, for example, is not necessarily part of the act of “initiating” such a report, as when the “beginning” of the report is performed by a first party (the initiating party) and the “reporting” itself is performed by a second party (the reporting party) different from the first party (the initiating party). Furthermore, the act of “reporting” need not be performed or fully completed by either the first party or the second party. It will be understood that the act of initiating may be fully performed in one jurisdiction or country, even if an acknowledgment of the commencement or of a subsequent act or one associated with the commencement occurs in a different jurisdiction or country.

[0144] As used in this document, “reporting” of data should be understood as an act of “reporting” that may require only one party (reporting party) to perform it. Furthermore, the act of “reporting” does not require the receipt (or confirmation of receipt) of such a report by another party (receiving party). The report may be a storage of data or the display of data in a location accessible to an intended recipient and may still be considered a report even when the intended recipient does not access or analyze the data.

[0145] As used in this document, “transmitting” information should be understood as an act of “transmission” which may require Petition 870250093064, dated 10 / 10 / 2025, pages 264 / 296 46 / 49 only one part (the transmitting part) needs to be performed. Furthermore, the act of “transmission” does not require a receiver (e.g., receiving party) or a receipt (e.g., confirmation of receipt) of the information being transmitted.

[0146] As used in this document, “requesting” a separation (or commencement of a separation method) should be understood as an act of “requesting” that may require only one party (the requesting party) to perform. Furthermore, the act of “separating,” requested by the act of “requesting,” may be performed by another party (the separating party). Additionally, the act of “requesting” may only be intended or commenced and need not be performed or fully completed (e.g., when no separation results from the act of “requesting” such separation). In one example, the act of “requesting” a separation (or commencement of a separation method) of gaseous CO2 might involve a carbon dioxide removal service provider associating carbon dioxide that has already been removed from the atmosphere (or is currently in an active removal process) with a subsequent request for a separation.It will be understood that the act of applying may be fully carried out in one jurisdiction or country, even if an acknowledgment of the application or a subsequent act or act associated with the application occurs in a different jurisdiction or country.

[0147] As used in this document, “receiving” a report or an indication of the report should be understood as an act of “receiving” that does not require a sender (e.g., sending party). Receiving may be storing data or displaying the data in a location accessible to the intended recipient, and may still be considered receiving even when the intended recipient does not access or analyze the data.

[0148] As can be understood, the first quantity, the second quantity, and the portion of the first quantity can be estimated or projected values. It can be further understood that the gas Petition 870250093064, dated 10 / 10 / 2025, pages 265 / 296 47 / 49 Carbon dioxide released or dispersed at the first location may not necessarily include or be the same CO2 molecules separated or collected at the second location, and the second quantity may be an equivalent amount of CO2 that was released or dispersed. The CO2 in the portion of the first quantity may be in a non-gaseous form. The portion of the first quantity or the second quantity may refer to carbon dioxide that is trapped in the sorbent, as disclosed herein, or that has been stored or otherwise converted into another form. The portion of the first quantity or the second quantity may also include gases other than carbon dioxide. For example, the second quantity may be in a non-gaseous form or combined with other materials.

[0149] As used in this document, a “carbon capture device” refers to any one or more devices, as disclosed in this document, that have the capability to separate gaseous CO2 from the atmosphere at the location where the device is installed or situated. The carbon capture device may refer to a single device or a plurality of devices, or to an installation containing one or more such devices or component devices acting together. The device may include, for example, the desorption medium source(s) and the adsorbent structure(s) as disclosed in this document. The device may be operated by a user or operator using an electronic device. The device may generate data associated with its operation, for example, such as data that may be detected by one or more sensors and / or data that may include log data, among other examples.

The processing unit may include a central processing unit (CPU), a Petition 870250093064, dated 10 / 10 / 2025, pages 266 / 296 48 / 49 microprocessor, a system-on-a-chip (SoC), or any other processor capable of performing such operations. The memory unit may be a non-transient, computer-readable storage medium that stores one or more programs or instructions that, when executed in the processing unit, cause the processing unit or electronic device to perform one or more methods as disclosed herein. The memory unit may include one or more memory chips capable of storing data and allowing the storage location to be accessed by the processing unit(s), for example, volatile or non-volatile memory, static or dynamic random access memory, or any variant thereof. In some examples, the electronic device may be referred to as a computing device.

[0151] The technical advantages of removing gaseous CO2 from an atmosphere using the methods or processes disclosed in this document include, but are not limited to, facilitating a network of entities and / or devices that have the capability to communicate with other entities and / or devices to provide instructions remotely or facilitate the separation and removal of gaseous CO2 without requiring physical presence on-site to do so. Furthermore, the methods and processes disclosed in this document provide a robust inter-institutional communication network so that each entity (which may be an institution associated with a physical location) has the capability to direct or initiate the separation and removal of gaseous CO2 at multiple locations simultaneously, as well as the ability to flexibly change the location at which the separation and removal of gaseous CO2 is determined to have been removed.The change of location can be performed in real time or near real time, so that there is a minimum time interval between when the instructions are given and when the separation of gaseous CO2 occurs at the designated location, for example. In some examples, the methods or processes disclosed in this document provide a flexible communication network in which the entity or device performing the separation and removal of CO2... Petition 870250093064, dated 10 / 10 / 2025, pp. 267 / 296 49 / 49 gaseous CO2 at the designated location can provide a timely report (e.g., summary of the operation and / or invoice for the service provided) associated with the amount of gaseous CO2 that was removed during a predetermined period of time.
