Abstract
Description
Technical Field
[0001] This invention relates to a method for producing syngas by gasifying waste streams such as automobile crush residue. Background Technology
[0002] Waste streams containing shredded residue are widely produced and are typically incinerated to generate heat, etc. There is a growing demand for more sustainable use of this shredded residue, particularly automotive shredded residue (ASR).
[0003] Plasma gasification using at least one plasma torch is a suitable technique for converting such crushed residues, particularly automotive crushed residues, into syngas. The syngas contains CO and H2, which are suitable, for example, as reactants in the manufacture of polymers and other materials contained in automobiles and other vehicles. At least one plasma torch included in the plasma gasifier has a lower operating threshold (“mindestlast” in German). Therefore, a minimum amount of electrical power and a minimum amount of at least one (preferably) gaseous plasma source are required to operate the at least one plasma torch and thereby convert the crushed residue into syngas. When the at least one plasma torch operates below its operating threshold, an undesirable large amount of at least one plasma source is discharged from the plasma gasifier along with CO and H2 from the reaction product syngas. This is the case when there is insufficient crushed residue available and / or feed into the plasma gasifier. The undesirable large amount of at least one plasma source must then be separated from the syngas by energy-intensive methods using expensive equipment to obtain CO and H2 of the purity required for downstream processes. The large amount of at least one plasma source to be separated from the syngas may even prevent the sustainability of the entire process.
[0004] The object of this invention is to provide a method for converting a waste stream containing crushed residues, such as automotive crushed residues, into syngas, wherein the method has a reduced product carbon footprint and / or reduced CO2 emissions compared to prior art methods.
[0005] Another objective is to provide a method for producing syngas from crushed residue, wherein the method does not result in an increase in the amount of unwanted plasma source in the syngas when the amount of crushed residue fed into the plasma gasifier is below the operating boundary value of at least one plasma torch inside the plasma gasifier. Summary of the Invention
[0006] These problems are addressed by a method for producing syngas from feedstocks, the method comprising the following steps:
[0007] (i) A first raw material F1 is provided, wherein the first raw material F1 comprises sorted crushed residue SSR, the sorted crushed residue SSR being formed by sorting unsorted crushed residue NSR.
[0008] The unsorted fragmented residue (NSR) comprises metal fragments and / or non-metallic inorganic fragments, as well as fragments of at least one polymer selected from the group consisting of polyamides, polyisocyanate addition polymers, rubbers, epoxy resins, and polyolefins.
[0009] The unsorted crushed residue NSR is pre-sorted to form the sorted crushed residue SSR, preferably pre-sorted in the following order and manner:
[0010] a) Optionally, further reduce the size of the metal fragments and / or non-metallic inorganic fragments and at least one polymer fragment, and
[0011] b) Separate the metal fragments and / or the non-metallic inorganic fragments.
[0012] Thus, through step b), the sorted crushed residue SSR consists of metal-poor fragments and / or non-metallic inorganic fragments.
[0013] (ii) Provide at least one additional raw material F2,
[0014] (iii) The first raw material F1 provided in step (i) is combined with at least one additional raw material F2 provided in step (ii) and converted into a gas stream GS1 in at least one plasma gasification furnace PG, the gas stream GS1 comprising syngas, wherein the syngas comprises H2, CO and CO2, and wherein the at least one plasma gasification furnace PG comprises at least one plasma torch, the at least one plasma torch being electrically operated, wherein the plasma in the at least one plasma gasification furnace PG is generated by at least one plasma source PS, and
[0015] (iv) At least a portion of the CO2 is removed from the gas stream GS1 formed in step (iii) in the syngas upgrade unit SUP, thereby forming a gas stream GS2.
[0016] These problems are addressed by plasma gasification in at least one plasma gasifier PG for converting sorted crushed residue SSR into syngas, the sorted crushed residue SSR being formed by sorting unsorted crushed residue NSR, wherein the unsorted crushed residue NSR comprises metal fragments and / or glass fragments, wherein the unsorted crushed residue NSR is pre-sorted to form the sorted crushed residue SSR, preferably in such a sequence as a) optionally further reducing the size of the unsorted crushed residue NSR and b) sorting out the metal fragments and / or glass fragments from the unsorted crushed residue NSR, wherein the sorted crushed residue SSR comprises at least one polymer selected from the group consisting of polyamides, polyisocyanate addition polymers, rubbers, epoxy resins, and polyolefins.
[0017] These problems are further addressed by providing at least one second feedstock F2 and converting it together with the first feedstock F1, which includes sorted crushed residue SSR, in a plasma gasifier comprising at least one plasma torch, wherein the plasma in the at least one plasma gasifier PG is generated by at least one plasma source PS. This prevents unwanted large quantities of at least one plasma source PS from entering the syngas.
[0018] Further aspects of the invention will become apparent to those skilled in the art directly from the foregoing and the following description and examples. Detailed Implementation
[0019] definition:
[0020] In the context of this specification and the appended claims, the term "about" preferably means a deviation of ±10% from the value described therein. In the context of this invention, the term "combination thereof" includes one or more of the listed elements. In the context of this invention, the term "mixture thereof" includes one or more of the listed elements.
[0021] "Resettlement-derived fuel" (RDF) is defined in this paper as fuel derived from various types of waste, such as municipal solid waste (MSW), industrial waste, or commercial waste. RDF is primarily composed of combustible components of such waste, such as non-recyclable plastics (excluding PVC), cardboard, labels, and other corrugated materials. These fractions are separated through various processing steps, such as screening, air classification, ballistic sorting, sorting of ferrous and non-ferrous metals, glass, stone, and other foreign materials, and chopping into uniform particle sizes, or pelletizing to produce homogeneous materials that can be used as feedstock for gasification processes (Y. Yang et al., Gasification of refuse-derived fuel from municipal solid waste for energy production: a review, Environmental Chemistry Letters (2021) 19, 2127-2140 (https: / / doi.org / 10.1007 / s10311-020-01177-5).
[0022] The term "downstream of" is defined in this document with respect to a series of unit operations as located on one side immediately adjacent to the flow direction of the fluid passing through the series of unit operations.
[0023] The term “fluidly connected to” in relation to two or more units is defined herein as a fluid (such as particulate solids, liquids, gases, and mixtures thereof) that can flow from one such unit to another and through and / or along such analytical units. Two units that are “fluidly connected” to each other are connected, for example, by one or more pipes connected to each other, or by a screw conveyor, or by an extruder, or by a solid pump.
[0024] The method according to the present invention is described in detail below.
[0025] In step i) of the method according to the invention, a first raw material F1 is provided. The first raw material F1 comprises sorted crushed residue SSR, which is formed by sorting unsorted crushed residue NSR. The unsorted crushed residue NSR comprises metal fragments and / or glass fragments and fragments of at least one polymer selected from the group consisting of polyamides, polyisocyanate addition polymers, rubbers, epoxy resins, and polyolefins.
[0026] Unsorted shredded waste (NSR) is or includes, for example, automotive shredded waste (ASR), shredded electrical and electronic equipment (WEEE), and other types of shredded waste. Shredded electrical and electronic equipment (WEEE) preferably contains epoxy resin derived from printed circuit boards, etc., contained therein.
[0027] The unsorted crushed residue NSR is sorted to form sorted crushed residue SSR, preferably in the following order: a) optionally further reducing the size of the unsorted crushed residue NSR and b) separating metal fragments and / or non-metallic inorganic fragments from the unsorted crushed residue NSR.
[0028] Unsorted shredded residue (NSR) and sorted shredded residue (SSR) preferably comprise parts of end-of-life vehicles and / or shredded waste electrical and electronic equipment. Particularly preferred first feedstock F1 comprising parts of end-of-life vehicles is automotive shredded residue (ASR), which is described in more detail below:
[0029] Automotive debris can be obtained, preferably, through the crushing of vehicles. More preferably, automotive debris can be obtained through vehicle decontamination, vehicle dismantling, vehicle crushing, and separation of metal particles from the crushed vehicle.
[0030] The method described for a) optionally further reducing the size of the metal fragments and / or non-metallic inorganic fragments and at least one polymer fragment, and b) sorting the metal fragments and / or non-metallic inorganic fragments in relation to the Automotive Crushed Residue (ASR) described below, can also be applied to other unsorted crushed residue NSR provided in step (i) to form a sorted crushed residue SSR that is depleted of metal fragments and / or non-metallic inorganic fragments compared to the unsorted crushed residue NSR by step b). Non-metallic inorganic fragments are, for example, glass fragments.
[0031] Vehicles in Automotive Shrapnel Residue (ASR) are typically end-of-life vehicles (also known as “ELVs”) that are at least 15 years old. Vehicles can be passenger cars, light or heavy-duty trucks, motorcycles, multi-purpose vehicles, agricultural vehicles, or recreational vehicles. Vehicles can be electric vehicles, such as pure electric vehicles or hybrid electric vehicles.
[0032] In vehicle decontamination, harmful liquids (such as fuel, lubricating oil, coolant, brake fluid) and batteries can be removed from the vehicle before crushing.
[0033] Vehicle dismantling can include the selective removal of parts such as engines, transmissions, tires, glass, and plastics for reuse as spare parts in the second-hand market. Dismantling can also include the removal of larger plastic components, such as bumpers, dashboards, and fluid containers, for individual recycling of the plastics.
[0034] ASR may include additional waste from other sources. For example, trash from a previous owner may remain in the trunk or interior of the vehicle. An advantage of the method of the present invention is that it can handle a wide variety of ASR compositions.
[0035] Crushing can be carried out using a vehicle crusher. Vehicle crushers are manufactured in various sizes. Typically, a vehicle crusher includes a heavy-duty, high-speed rotating rotor that can rotate in a vertical or horizontal plane and is usually equipped with a swing hammer. The vehicle crusher tears and crushes the vehicle wreckage until its parts are reduced to fragments. The fragments can then pass through a grating and exit the rotor housing. The vehicle crushing residue preferably accounts for 10 to 40 wt.% of the original vehicle weight, more preferably 15 to 35 wt.% and most preferably 20 to 30 wt.% of the original vehicle weight.
[0036] In step a), the size of the fragments may be further reduced to obtain a preferred fragment size, i.e., at least 90 wt.% of the crushed residue fragments formed in step a) are less than 5 cm, preferably at least 95 wt.% are less than 5 cm, and more preferably at least 95 wt.% are less than 3 cm. If the unsorted crushed residue NSR already has a preferred fragment size, i.e., at least 90 wt.% of the crushed residue fragments formed in step a) are less than 5 cm, preferably at least 95 wt.% are less than 5 cm, and more preferably at least 95 wt.% are less than 3 cm, then step a) may preferably be omitted.
[0037] The method used in step a) is selected from the group consisting of crushing, grinding, milling, sieving, grading, and combinations thereof. Optionally, step a) may further include optical and / or manual sorting to remove excessively large fragments. Such methods are known to those skilled in the art and can be applied to the given unsorted crushed residue NSR provided in step (i).
[0038] Following optional step a), after crushing and further reducing in size, metal fragments such as ferrous and nonferrous metal fragments and nonmetallic inorganic materials (“inert materials”) such as glass or sand can be separated from the crushed vehicle in step b). Step b) includes at least removing metal fragments and / or glass fragments from the unsorted crushed residue NSR. Metal fragments typically, but not always, include ferrous and nonferrous metal fragments.
[0039] Ferrous metal fragments can be removed using magnetic separators. Magnetic separators typically utilize the magnetic properties of ferrous metals to attract and separate them from non-magnetic materials. Generally, the material is fed onto a conveyor belt or vibrating feeder, and as the material moves along the conveyor belt, the magnetic separator generates a strong magnetic field (e.g., a magnetic field is generated by passing an electric current through a coil, which produces a magnetic force). When the material passes through the magnetic field, the magnetically charged ferrous metals can be attracted to the magnetic separator. Once the ferrous metals are attracted to the magnetic separator, they can be separated from the remaining waste and collected separately. This can be accomplished using separate chutes or conveyor belts to guide the separated ferrous metals to a designated collection area.
[0040] Non-ferrous metal fragments can be separated from broken vehicles using eddy current separators, density separation methods (e.g., heavy medium sinking / floating units), manual sorting, and combinations thereof. Suitable eddy current separators utilize the principle of electromagnetic induction to generate eddy currents, which in turn generate magnetic fields that repel non-ferrous metals. Typically, material is fed onto a conveyor belt or vibrating feeder, and as the material moves along the conveyor belt, the eddy current separator generates an alternating magnetic field. When this alternating magnetic field interacts with a conductive non-ferrous metal (such as aluminum or copper), eddy currents can be induced within the conductive non-ferrous metal due to electromagnetic induction. These eddy currents typically generate their own magnetic fields, which produce repulsive forces against the magnetic field of the eddy current separator. This repulsion can cause the non-ferrous metals to be pushed away from the separator, thus separating them from the rest of the material.
[0041] The automotive debris preferably contains up to 15 wt.-%, more preferably up to 10 wt.-%, and most preferably up to 5 wt.-%, of metal fragments, such as ferrous and nonferrous metal particles.
[0042] Typically, 60 to 90 wt.% of a vehicle's weight is metal, which can be separated from a broken vehicle.
[0043] Non-metallic inorganic materials (“inert materials”) such as glass or sand are preferably separated by density separation. Suitable methods for density separation include cyclone separation, jigging, air separation, or sedimentation-flotation separation. Automotive debris may preferably contain up to 15 wt.% of glass fragments, more preferably up to 10 wt.% of glass fragments, and most preferably up to 5 wt.% of glass fragments, such as broken window glass fragments.
[0044] Cyclone separation is a method commonly used to separate materials based on their density and size using a device called a cyclone separator. A cyclone separator typically consists of a cylindrical body with a conical base and an inlet and outlet at the top. The inlet can be tangentially connected to the body, which creates vortex motion inside the cyclone separator. As the material rotates inside the cyclone separator, centrifugal force is generated, causing denser and larger particles to move towards the outer wall of the cyclone separator, while lighter and smaller particles tend to remain near the center.
[0045] Jigging is a method of separating materials based on their density using a device called a jig, which typically consists of a rectangular or circular container with a screen or mesh at the bottom. This container can be mounted on a frame with mechanisms that move it up and down. The jig can be filled with water, and a pulsating flow of water is introduced from the bottom of the container. This pulsation causes the material to move up and down within the container. More dense particles may tend to settle faster and move towards the bottom of the container, while lighter particles tend to remain near the top.
[0046] Air separation is typically based on airflow, as seen in air classifier structures, which are typically vertical chambers with an inlet at the bottom and an outlet at the top. This chamber may contain a series of guide vanes or blades that generate centrifugal forces that separate the materials. Airflow is usually introduced from the bottom of the chamber, and this airflow causes the materials to move upwards and separate based on their density. Denser particles generally tend to move towards the outer walls of the chamber, while lighter particles tend to remain near the center. The separated material can be collected at different locations within the air classifier.
[0047] Sinking-float separation is generally based on the principle that materials of different densities will behave differently when placed in a fluid medium: denser materials typically sink, while less dense materials float. The fluid medium can be a heavy liquid, such as water or a specially formulated solution, or a finely ground powder. The liquid is usually chosen to have a density between that of the materials to be separated.
[0048] Automotive debris comprises fragments of various polymer vehicle parts, which contain at least one polymer selected from polyamides, polyisocyanate addition polymers, rubbers, and polyolefins. The fragments are selected from the following: bumpers, interior trim panels, dashboards, cable insulation, electrical insulation materials, flexible foam seats, foam insulation boards, automotive suspension bushings, electrical potting compounds, body parts, pillar covers, spoiler polymer parts coated with automotive paint, wheel covers, gears, bushings, cams, bearings, weather-resistant coatings, interior and exterior trim, fuel systems, gear housings, headlight retainers, engine hoods, connector housings, door handles, carburetor components, exterior rearview mirror components, windshield wiper components, windshield wiper protective housings, decorative grilles, cover strips, roof rails, window frames, sliding roof frames, antenna covers, headlights and taillights, radiator grilles and exterior body parts, engine hoods, cylinder head covers, intake manifolds, cylinder head covers, engine hoods, supercharger cooler housings, supercharger cooler valves, preferably at least one of which is included in the sorted crushed residue SSR.
[0049] The automotive debris preferably contains at least 30 wt.-%, more preferably at least 40 wt.-%, and most preferably at least 50 wt.-%, of polymeric vehicle parts (referred herein as "fragments containing at least one polymer"), wherein the at least one polymer is selected from the group consisting of polyamides, polyisocyanate addition polymers, rubbers, and polyolefins. Such fragments containing at least one polymer are particularly suitable for conversion into syngas in at least one plasma gasifier PG in step (iii).
[0050] Epoxy resins are typically found in shredded waste electrical and electronic equipment, and can also be found in automotive shredded waste.
[0051] The polyamides that may be included in the sorted crushed residue SSR are selected from the group consisting of polyamide 6 (PA6), polyamide 66 (PA66), and mixtures thereof. These polyamides may contain fillers.
[0052] Polyisocyanate addition polymers that may be included in the sorted crushed residue SSR are selected from the group consisting of polyurethane (PU), thermoplastic polyurethane (TPU), polyurea, polyisocyanurate (PIR), and mixtures thereof. These polyisocyanate addition polymers may contain fillers.
[0053] The rubber that may be included in the sorted crushed residue SSR is selected from the group consisting of: natural rubber, styrene-butadiene rubber, butyl rubber, ethylene propylene diene monomer rubber, chloroprene rubber, nitrile rubber and silicone rubber.
[0054] Polyolefins that may be included in the sorted crushed residue SSR are selected from the group consisting of: low-density polyethylene (LDPE), high-density polyethylene (HDPE), polyethylene (PE), polypropylene (PP), and mixtures thereof. These polyolefins may contain fillers.
[0055] The sorted crushed residue SSR more preferably comprises at least two different polymers from the group consisting of: polyamides, polyisocyanate addition polymers, rubbers, epoxy resins, and polyolefins.
[0056] The automotive debris may contain up to preferably 15 wt.% of wood and cardboard, more preferably up to 10 wt.% of wood, and most preferably up to 5 wt.% of cardboard. Such components may be retained in the first feedstock F1 used in the gasification process in step (iii) because they can be converted into syngas.
[0057] Preferably, the unsorted crushed residue NSR and / or the sorted crushed residue SSR are dried before step (iii).
[0058] In step (ii), at least one additional raw material F2 is provided and subjected to a gasification process in step (iii), wherein the gasification process includes at least one plasma gasifier PG, and wherein the additional raw material F2 is injected "together" with the sorted and crushed residue SSR provided in step (i) into at least one plasma gasifier PG. The meaning of "together" depends on the type of the at least one additional raw material F2 and the type of plasma gasifier PG used in step (iii), and is explained in detail below.
[0059] Preferably, the at least one additional feedstock F2 provided in step (ii) is selected from the group consisting of or including: biomass, waste-derived fuel (RDF), pyrolysis oil derived from plastic waste, pyrolysis oil derived from scrap tires, pyrolysis oil derived from biomass, heating oil, vacuum residue, preferably vacuum distillation residue, crude oil residue, heavy crude oil, extra-heavy crude oil, tar sands asphalt, viscosity-reducing cracking bottom residue, deasphalting bottom residue, C5 asphaltene fraction, high-viscosity residue, fuel oil, pyrolytic gasoline, tire pyrolysis oil (TPO), waste oil, used oil, municipal solid waste (MSW), coal, tar, natural gas, contaminated vehicle parts and mixtures thereof.
[0060] The term "biomass" includes, but is not limited to, wood, wood pellets, sawdust, straw, lignocellulosic biomass, energy crops, algae, bio-based oils and bio-based fats (preferably hydrated).
[0061] The biomass is preferably roasted or converted into pyrolysis oil via pyrolysis, and then used as at least one additional feedstock F2 in step (iii). Municipal solid waste (MSW) is optionally pretreated by methods such as drying, crushing, sorting, and inert matter removal, and is preferably used in step (iii) in the form of waste-derived fuel (RDF). Preferably, the roasted biomass is preheated to a temperature such as 200°C, and then fed into the at least one plasma gasification furnace PG as at least one additional feedstock F2 in step (iii).
[0062] "Contaminated vehicle parts" are suitable as an additional raw material F2. Such contaminated vehicle parts are made of plastic materials and are contaminated by contaminants such as gasoline or diesel fuel due to physical and chemical contact between the vehicle parts and the corresponding contaminants for up to one year. Contaminated vehicle parts are, for example, gas cylinders (made of plastic materials such as polyethylene) contaminated with gasoline or diesel fuel (=contaminants). Preferably, the contaminated vehicle parts are removed from the respective vehicle before the vehicle is crushed. Crushed vehicle parts are defined as automotive slag residue (ASR), which is the first raw material F1 in the method according to the invention. Therefore, such contaminated vehicle parts are preferably not included in the automotive slag residue (ASR). The dismantling of contaminated vehicle parts can be carried out manually by humans and / or automatically by robots.
[0063] Optionally, at least one additional raw material F2 provided in step (ii) is preferably selected from the group consisting of or including: biomass, waste-derived fuel (RDF), pyrolysis oil made from plastic waste, pyrolysis oil made from scrap tires, pyrolysis oil made from biomass, municipal solid waste (MSW), coal, contaminated vehicle parts and mixtures thereof.
[0064] At least one additional raw material F2 is preferably pretreated prior to step (ii) by a method selected from or consisting of the following: sorting, sieving, milling, grinding, pyrolysis, roasting, metal sorting and combinations thereof.
[0065] The weight ratio of "first raw material F1 : other raw material F2" preferably ranges from 10 : 1 to 1 : 10, more preferably from 1 : 2 to 1 : 10, and most preferably from 1 : 5 to 1 : 10. Preferably, "other raw material F2" means all the other raw materials F2 combined when more than one other raw material F2 is used.
[0066] Preferably, the additional liquid feedstock F2 (such as bio-based oil and pyrolysis oil) is preheated and / or pressurized to >1 bar (absolute value), more preferably >2 bar (absolute value), and most preferably about 4 bar (absolute value), before being fed into at least one plasma gasifier PG. Suitable devices for preheating and / or pressurizing the liquid feedstock for feeding into the at least one plasma gasifier PG are known in the art, including, for example, flap valves and locks, as well as annual gaps, pressure nozzles and pressure atomizers, and can be adapted by a technician to the given additional feedstock F2. The at least one plasma gasifier PG is most preferably a fixed-bed plasma gasifier PG.
[0067] An overview of the plasma gasifier (PG) is provided, for example, in James G. Speight, Handbook of Gasification Technology, Scrivener Publishing and Wiley, 2020, Chapter 8.4.2, pages 259-262.
[0068] At least one plasma gasifier PG has at least one inlet and at least one outlet, through which a first feedstock F1 and at least one additional feedstock F2 are fed into the at least one plasma gasifier PG, and through which syngas is discharged from the at least one plasma gasifier PG. Preferably, the at least one plasma gasifier PG has more than one inlet. Thus, at least one additional feedstock F2 and the first feedstock F1 can be fed separately into the at least one plasma gasifier PG through separate inlets. The term "inlet" includes openings in the at least one plasma gasifier PG, such as flap valves and locks, as well as annual gaps (as in a dual-fluid atomizer), pressure nozzles, and pressure atomizers that are part of the burner. The plasma is formed by at least one plasma torch and at least one plasma source PS.
[0069] A plasma gasifier PG is preferred for a first feedstock F1 along with at least one additional feedstock F2 because the types of feedstocks with different calorific values and availability can be better balanced in such a plasma gasifier PG to achieve consistent syngas production (e.g., yield, molar ratio H2:CO). Furthermore, less CO2 is produced in the plasma gasifier PG by the gasification of the first feedstock F1, particularly when steam is used as the plasma source PS and when at least one plasma torch is operated using electricity from a renewable source. Thus, less CO2 is formed compared to all gasifier types that rely on generating heat through (partial) oxidation.
[0070] Plasma gasification is a high-temperature waste treatment process that uses plasma (a gas composed of highly charged particles) to decompose organic matter into gas. In this process, a first feedstock F1 and at least one additional feedstock F2 are fed into a plasma gasification furnace PG. Preferably, the first feedstock F1 and at least one additional feedstock F2 are fed into the plasma gasification furnace PG, where they are exposed to at least one plasma torch, which ionizes the first feedstock F1 and at least one additional feedstock F2 and generates plasma. The plasma is generated by means of at least one plasma torch, more preferably, by means of at least two plasma torches. Most preferably, the plasma gasification furnace comprises three or more plasma torches. Preferably, at least one plasma torch is installed in the portion of the plasma gasification furnace PG where the first feedstock F1 and / or at least one additional feedstock F2 is fed into the plasma gasification furnace PG, and one or two plasma torches are installed in the portion of the plasma gasification furnace PG where the syngas exits the plasma gasification furnace PG (most preferably in an arrangement that forces the syngas through the one or two plasma torches). The high temperature inside the plasma gasifier PG (which can reach up to about 10,000 K) causes the first feedstock F1 and at least one other feedstock F2 to evaporate and decompose into constituent components, including hydrogen, carbon monoxide and methane.
[0071] Most preferably, at least one plasma gasifier PG is a fixed-bed plasma gasifier. Fixed-bed plasma gasifier PGs are better suited for the first feedstock F1 because the non-metallic inorganic fragments they contain cause less clogging and associated undesirable effects compared to other types of plasma gasifier PGs (such as fluidized-bed and entrained-flow plasma gasifier PGs).
[0072] Preferably, the power for operating at least one plasma torch of at least one plasma gasifier PG is generated from a renewable source. More preferably, the power for operating at least one plasma torch of at least one plasma gasifier PG is generated from at least one source selected from the group consisting of: solar energy, wind energy, tidal energy, nuclear energy, geothermal energy, and combinations thereof.
[0073] The plasma in at least one plasma gasifier PG is generated by at least one plasma source PS, which is selected from the group consisting of steam, oxygen, CO2, air, and combinations thereof. In the case of syngas with a desired molar ratio of H2:CO > 1, steam is most preferred as the plasma source PS. The syngas exiting the plasma gasifier PG also contains at least one plasma source PS or a portion thereof.
[0074] In step (iii), at least one plasma source is co-fed into at least one plasma gasifier PG. Most preferably, in step (iii), steam is co-fed into at least one plasma gasifier PG. The weight ratio of "(combined first feedstock F1 and optional additional feedstock F2) : steam" is preferably in the range of 1:1 to 10:1, more preferably 2:1 to 10:1, and most preferably 5:1 to 10:1 or higher.
[0075] Preferably, the ratio of "electrical power applied to one or more plasma torches: mass of the generated gas stream GS1" is preferably in the range of 0.1 to 15 kW / h: kg, more preferably 0.5 to 10 kW / h: kg, and most preferably 1 to 8 kW / h: kg. This ratio is preferred when using a first feedstock F1 to maintain the desired process conditions inside at least one plasma gasifier PG.
[0076] Preferably, the first raw material F1 and at least one other raw material F2 are compressed to a maximum of 4 bar (absolute value) and then fed into at least one plasma gasification furnace PG.
[0077] The temperature of the gas exiting the plasma gasifier PG is preferably in the range of 1100°C to 1400°C, and most preferably about 1300°C. The pressure of the syngas exiting the plasma gasifier PG is preferably at least 0.7 bar (absolute value), and more preferably at least 1 bar (absolute value). The residence time of the reactants inside the plasma gasifier PG is at least 2 to 3 s. The plasma is preferably generated by a gas (plasma source PS) selected from the group consisting of CO2, steam, O2, air, and mixtures thereof. More preferably, the plasma is generated by CO2, steam, or a mixture of CO2 and steam.
[0078] Preferably, the first feedstock F1 is fed into the plasma gasifier PG through an opening independent of the opening for feeding at least one other feedstock F2. Preferably, steam is fed into the plasma gasifier through another opening.
[0079] The gas stream GS1 then exits at least one plasma gasifier PG. The gas stream GS1 contains CO and H2 (“syngas”), byproducts of the gasification reaction such as CO2, CH4, and ash, and at least one plasma source PS or a portion thereof. The syngas formed in step (iii) preferably contains < 15 Vol.-% CO2, more preferably < 10 Vol.-% CO2, and most preferably < 8 Vol.-% CO2.
[0080] The method includes an additional step (iv), in which impurities and other unwanted components, such as at least one plasma source PS or a portion thereof, are removed from the gas stream GS1 formed in step (iii) within a gas processing unit GTU. This yields a gas stream GS2 having a first molar ratio of H2:CO.
[0081] Typical impurities in gas stream GS1 include chlorides, sulfur-containing organic compounds such as sulfur dioxide, trace heavy metals (e.g., as corresponding salts), tar / condensable hydrocarbons, particulate residues, and at least one plasma source PS or a portion thereof. Various chemical and / or physical methods for removing such impurities from gas stream GS1, such as filtration, washing, condensation, and absorption / adsorption, are known and can be selected and tailored according to the type and corresponding concentration of impurities in gas stream GS1 and the tolerance for such impurities in another process FP1. Some selected methods for removing impurities from gas stream GS1 will be discussed in more detail. One or more of these methods can also be implemented in a gas handling unit GTU. However, the choice of method does not limit the scope of the invention.
[0082] Other gaseous substances such as HCl and H2S are formed, and / or these substances are separated from gas stream GS1 in the gas processing unit GTU. Impurities are removed from gas stream GS1, and gas stream GS2 with a first molar ratio of H2:CO is obtained.
[0083] Particulate impurities can be removed from gas stream GS1 by cyclone separators and / or filters; chlorides are removed by wet scrubbing; trace heavy metals are removed by catalytic hydrolysis to convert sulfur-containing organic compounds into H2S; and acid gas removal is used to extract sulfur-containing gases such as H2S. Large and (fine) particles (such as dust) in gas stream GS1 can also be removed by quenching in the soot water scrubbing unit.
[0084] After the gas stream GS1 leaves the gasifier, particulate impurities can optionally be removed directly from the gas stream GS1 via a cyclone separator and / or filter. Therefore, particle removal from the gas stream GS1 can be part of the gasifier and / or part of a gas processing unit GTU fluidly connected to at least one plasma gasifier PG.
[0085] After the gas stream GS1 exits at least one plasma gasifier PG, fine particles can optionally be removed directly from the crude syngas using a filter. Therefore, the removal of fine particles from the gas stream GS1 can be part of at least one plasma gasifier PG and / or part of a gas processing unit GTU fluidly connected to at least one plasma gasifier PG.
[0086] The optional gas treatment unit (GTU) preferably includes a unit for removing at least a portion of CO2 from the gas stream GS1 in step (iv) by a method selected from or comprising the group consisting of: absorption, adsorption, membrane separation, cryogenic separation, and combinations thereof. Most preferably, the unit is a washing unit, such as "amine washing" or "methanol washing," which uses one or more amine compounds, such as alkanolamines or methanol, to absorb CO2. Such units are known in the art and can be adapted by a person skilled in the art to remove at least a portion of CO2 from the gas stream GS1.
[0087] Optionally, CO and / or H2 can be separated from the gas stream GS1. CO can be separated from the gas stream GS1 in a syngas separation unit, which is optionally downstream of and fluidly connected to at least one gasifier G. CO can be separated from the gas stream GS1 by cryogenic separation methods, often referred to as "cold boxes," which utilize the different boiling points of CO and H2. H2 can be separated using H2-selective membranes, which permeate through the membranes and are thus separated from the GS1 stream.
[0088] Gas stream GS1 has a first molar ratio of H2:CO. Optionally, gas stream GS1 is then preferably subjected to a water-gas shift reaction in a water-gas shift unit. This increases the H2 content in gas stream GS1 by causing a portion of the CO in gas stream GS1 to react with water to form additional H2 and CO2, thereby forming gas stream GS2 with a second molar ratio of H2:CO, which exits the water-gas shift unit. The H2 content in gas stream GS2, exiting the water-gas shift unit and having the second molar ratio of H2:CO, is higher than the content in gas stream GS1, exiting at least one gasifier and having the first molar ratio of H2:CO. The hydrogen content in gas stream GS1 can also be increased, for example, by adding hydrogen supplied from another source, such as by preferably using hydrogen formed by electrolyzing water with electricity from a renewable source (such as solar and / or wind power).
[0089] The water-gas shift reaction will be carried out in a temperature range of approximately 200°C to approximately 480°C using a variety of catalysts (such as copper-zinc-aluminum catalysts and chromium or copper-promoted iron-based catalysts).
[0090] Optionally, the gas stream GS2 can be compressed to a pressure in the range of 1.5 to 4 bar (absolute value).
[0091] Optionally, at least a portion of the CO2 separated from the gas stream GS1 in step (iv) is co-fed with a first feedstock F1 and optionally an additional feedstock F2 into at least one plasma gasifier PG, thereby converting it into syngas. Such CO2 is not considered additional feedstock F2. The weight ratio of CO2 to the combined feedstocks F1 and F2 fed into the at least one plasma gasifier ranges from 0 to 2, preferably from 0 to 1.5, and more preferably from 0 to 1. Thus, unwanted CO2 formed during the gasification process of the first feedstock F1 and at least one additional feedstock F2, or supplied as a plasma source PS, can be used as an additional feedstock for the production of syngas.
[0092] Furthermore, CO2 from other sources (such as other chemical processes) can optionally be co-fed with a first feedstock F1 and at least one additional feedstock F2 into at least one plasma gasifier PG, thereby being converted into syngas. Thus, unwanted CO2 from other sources can be used as an additional feedstock for the production of syngas.
[0093] Optionally, the gas stream GS2 is then subjected to an additional process FP1 selected from the group consisting of methanation, alcohol synthesis (preferably methanol synthesis), and Fischer-Tropsch synthesis, thereby forming at least one first product stream PS1. The gas stream GS2 can also be used as fuel gas, and the optional additional process FP1 is briefly described below:
[0094] Optionally, gas stream GS2 can be converted to methane via a methanation reaction. The methanation reaction is described by chemical reaction schemes (1) and (2):
[0095] CO + 3H2 CH4 + H2O(1)
[0096] CO2 + 4H2 CH4 + 2H2O(2)
[0097] Methanation reactions and suitable methanation units are described, for example, in S. Rönsch, J. Schneider, S. Matthischke, M. Schlüter, M. Götz, J. Lefebvre, P. Prabhakaran, S. Bajohr: Review on methanation - From fundamentals to current projects; Fuel 166 (2016) 276-296 and can be selected and adapted by a person skilled in the art.
[0098] The methanation reaction is a catalytic reaction, for example, using an alumina-supported nickel catalyst, preferably a honeycomb catalyst, at 1 to 70 bar and 200°C to 700°C, preferably 5 to 60 bar, more preferably 10 to 45 bar and preferably 200°C to 550°C, more preferably 10 to 45 bar.
[0099] Alcohols such as methanol are another chemical product that can be produced from gas stream GS2 via an optional additional process FP1. Most preferably, methanol is produced from syngas in a low-pressure methanol process in, for example, an adiabatic reactor or a quasi-isothermal reactor, by a catalytic gas-phase reaction using a catalyst at a temperature of about 200°C to about 300°C. The catalyst is, for example, a mixture of copper and zinc oxides supported on alumina. Methanol synthesis suitable for combination with the production system according to the invention and various alternatives thereof are disclosed in Ullmann's Encyclopedia of Industrial Chemistry (2012), chapter “Methanol”, pages 3 to 12.
[0100] The gas stream GS2 can also optionally be converted to hydrocarbons such as light synthetic crude oil via an FT process in an optional Fischer-Tropsch (FT) reactor unit. These hydrocarbons are also referred to as "Fischer-Tropsch hydrocarbons". The light synthetic oil can be further converted to naphtha, light olefins, or diesel fuel via hydrocracking and / or isomerization. For the production of gasoline and light olefins, the FT process operates at a temperature range of approximately 330°C to approximately 350°C and a pressure of approximately 2.5 MPa (high-temperature FT process); for the production of waxes and / or diesel fuels, the process operates at a temperature range of approximately 220°C to approximately 250°C and a pressure of approximately 2.5 MPa to approximately 4.4 MPa (low-temperature FT process). Suitable reactors for the low-temperature FT process include tubular fixed-bed reactors and slurry-bed reactors. Suitable reactors for the high-temperature FT process include circulating fluidized-bed reactors and SAS (Sasol advanced synthol) reactors. Iron-based and / or cobalt-based catalysts are used in the FT process. Suitable combinations of Fischer-Tropsch synthesis with the production system according to the invention and various alternatives thereof are disclosed in Ullmann's Encyclopedia of Industrial Chemistry (2012), chapter “Coal Liquefaction”, pages 20-33.

[0201] The present invention will be further explained through the following non-limiting examples. Example
[0202] For the following example, a fixed-bed plasma gasifier PG is compared with a combination of fluidized-bed and entrained-flow gasifiers using conventional solid-feed gasifiers. As the main feed, automotive crushing residue with 50 wt.-% carbon, 6 wt.-% hydrogen, 10 wt.-% oxygen, 1 wt.-% nitrogen, 3 wt.-% sulfur, and 30 wt.-% ash (“inert matter”) is used as the first feedstock F1 for sorting.
[0203] Example 1 (This invention)
[0204] The plasma fixed-bed gasifier is fed with a mass ratio (kg:kg) of "first feedstock F1: first gas stream GS1" = 1.01. The first feedstock F1 is sorted automotive wreck residue as a sorting crushed residue SSR. The plasma is generated by steam, and for the desired amount of plasma, a mass ratio (kg:kg) of "steam: generated gas stream GS1" = 0.25 is used. The steam has a pressure of 5.4 bar and a temperature of 180°C. A ratio (kW / h:kg) of "electrical power applied to the plasma torch: mass of generated gas stream GS1" = 3.91 is used to achieve the desired gas phase temperature of 1350°C at the outlet of the fixed-bed plasma gasifier PG. The fixed-bed plasma gasifier PG operates under atmospheric pressure. In step (iv), all the CO2 generated in the gas stream GS1 is separated from the gas stream in the gas processing unit GTU and fed into the fixed-bed plasma gasifier PG. Therefore, no CO2 is emitted from this process. The molar ratio of H2:CO in gas streams GS1 and GS2 is 2.07.
[0205] Example 2 (contrast)
[0206] For comparison, a conventional solid-feed gasifier combination of 1. a fluidized bed gasifier and 2. an entrained gasifier was simulated (the fluidized bed gasifier generates a rough first gas stream GS1r from a first feedstock F1, which is then converted into a gas stream GS1 containing syngas in the entrained gasifier). The fluidized bed gasifier was fed with a mass ratio (kg:kg) "first feedstock F1 : generated first gas stream GS1r" = 0.98 kg. Additionally, oxygen was fed with a syngas ratio of 0.53 kg / kg, and steam was fed with rough syngas at a mass ratio (kg:kg) "steam : generated rough gas stream GS1" = 0.49 kg / kg for fluidization. The steam had a pressure of 5.4 bar and a temperature of 180°C. The rough first gas stream GS1r exiting the fluidized bed gasifier had a temperature of 850°C and a pressure of 4 bar. In the secondary reformer (gutter gas reactor), the crude gas stream GS1r is heated in the second gasifier (gutter gas reactor) by introducing additional oxygen at a mass ratio (kg:kg) "oxygen:produced first gas stream GS1" = 0.14 kg. A temperature of 1350°C is reached at the outlet of the gutter gasifier. In step (iv), CO2 from the synthesis gas contained in the produced gas stream GS2 at a CO2 ratio of 0.39 kg / kg is separated and subsequently discharged. The molar ratio of H2:CO in gas streams GS1 and GS2 is 0.94.
