Description

Process for manufacturing C6-C8 aromatic hydrocarbons from end-of-life vehiclesTechnical fieldThe process of the present invention relates to the manufacture of C6-C8 aromatic hydrocarbons by gasification of pre-sorted fractions from end-of-life vehicles.Background of the inventionThe requirement to provide base chemicals, monomers and polymers having a recycling content is growing in the chemical industry. In specific sectors such as the automotive market, specific levels of recycling content for polymers are in discussion and will be implemented as regulations sooner or later.Accordingly, there is a need to provide processes in which plastic waste is converted into important base chemicals such as benzene, toluene and xylene isomers having a recycling content. Even more pressing is the need to provide such processes for which feedstocks can be utilized which comprise at least a portion of plastic waste from end-of life vehicles such as plastic waste comprised in automotive shredder residue (ASR). Said base chemicals then serve as a raw material for synthesis of monomers and such monomers as building blocks in polymers of relevance for the automotive market. Several polymer types of relevance for the automotive market comprise monomers which are based on C6-C8 aromatic hydrocarbons. Furthermore, such processes must be tolerant to the high concentration of (mostly) inorganic fillers comprised in plastic waste from end-of-life vehicles. In addition, such process must be scalable and economic because the demand of polymers having a recycling content for use in new vehicles will be high in near future.A method for producing olefins and aromatic compounds from a feedstock is disclosed in US 2014 / 0228606 A1. A hydrocarbon feedstock is converted in the presence of a catalyst composition at a reactor temperature of 420 to 730 °C in a reactor to products of at least one of olefins and aromatic compounds within the reactor, at least some of the products being contained in a liquid product stream. The catalytic composition comprises a fluidized bed catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst.

Accordingly, the method disclosed in US 2014 / 0228606 A1 is a fluidized catalytic cracking process which is different form gasification methods in several aspects such as the reaction temperature range and residence time and the presence of specific zeolite catalyst which results in a specific product composition. As described in paragraph

RDF consists largely of combustible components of such waste, as non-recyclable plastics (not including PVC), paper cardboard, labels, and other corrugated materials. These fractions are separated by different processing steps, such as screening, air classification, ballistic separation, separation of ferrous and non-ferrous materials, glass, stones, and other foreign materials and shredding into a uniform grain size, or also pelletized to produce a homogeneous material which can be used as a 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).In step (i) of the process according to the present invention, at least one pre-sorted fraction PSE from end-of-life vehicles is provided as first feedstock F1 , wherein said at least one pre-sorted fraction PSE comprises at least one organic polymer.Said first feedstock F1 comprises at least one pre-sorted fraction PSE of end-of-life vehicles, said pre-sorted fraction PSE of end-of-life vehicles formed by sorting from a non-sorted shredder residue NSR of end-of-life vehicles. Said non-sorted shredder residue NSR comprises metal fragments and / or non-metallic inorganic fragments (such as glass fragments), and fragments of at least one polymer selected from the group consisting of polyamides, polyisocyanate polyaddition products, rubber, epoxy resins and polyolefins.Said first feedstock F1 comprises plastic waste previously comprised in end-of-life vehicles, such as in the plastic waste comprised in automotive shredder residue (ASR) which has been taken from end-of-life vehicles and then presorted to increase the amount of at least one polymer therein and reduce the amount of metals and / or non-metallic inorganic fragments comprised in end-of-life vehicles. Preferably, the first feedstock F1 comprises 1 to 50 wt.-% plastic waste from end-of-life vehicles, most preferably, the first feedstock F1 comprises 5 to 30 wt.-% plastic waste from end-of-life vehicles Plastic waste comprised in end-of-life vehicles is preferably selected from the group comprising polyolefins, polyamides, polyurethanes, polyesters, and mixtures thereof. Most preferably, the plastic waste from end-of-life vehicles comprised in the first feedstock F1 is automotive shredder residue (ASR).The non-sorted shredder residue NSR may further comprise shredded electric and electronic equipment devices (WEEE - waste electric and electronic equipment) and other types of waste which are shredded. Shredded electric and electronic equipment devices (WEEE - waste electric and electronic equipment) preferably comprises epoxy resins originating from printed circuit boards and the like comprised therein. Such WEEE optionally also have been part of the end-of-life vehicles.Said non-sorted shredder residue NSR is sorted to form the pre-sorted fraction PSE of end-of-life vehicles, preferably in this order, by a) optionally further reducing the size of said non-sorted shredder residue NSR and b) sorting out metal fragments and / or non-metallic inorganic fragments from said non-sorted shredder residue NSR.A particularly preferred first feedstock F1 comprising pre-sorted fractions of end-of-life vehicles is pre-sorted automotive shredder residue (ASR) which is described in more detail below:Automotive shredder residue is obtainable, preferably is obtained, by shredding vehicles. Preferably, the automotive shredder residue is obtainable by depollution of the vehicles, dismantling the vehicles, shredding the vehicles, and separating metal particles from the shredded vehicles.The methods described for a) optionally further reducing the size of said metal fragments and / or non-metallic inorganic fragments and fragments of at least one polymer and b) sorting out said metal fragments and / or said non- metallic inorganic fragments in respect to automotive shredder residue (ASR) described below can also be applied to other non-sorted shredder residue NSR provided in step (i) to form at least one pre-sorted fraction PSE of end-of-life vehicles which is depleted in metal fragments and / or in non-metallic inorganic fragments by step b) compared to the non-sorted shredder residue NSR. Non-metallic inorganic fragments are for example glass fragments.The vehicles in automotive shredder residue (ASR) are typically end-of-life vehicles (also called “ELV”), which are typically at least 15 years old. The vehicles can be passenger cars, light-duty or heavy-duty trucks, motorbikes, a utility vehicle, an agricultural vehicle, or recreational vehicles. The vehicle can be an electric vehicle, such as a fully electric vehicle or a hybrid electric vehicle.In depollution of vehicles hazardous liquids such as fuel, lubricating oil, coolants, brake fluids and batteries can be removed from the vehicles prior to shredding.The dismantling of vehicles may comprise selective removal of parts, such as engines, gearboxes, tires, glass, and plastics, for being reused as spare parts for the second-hand market. The dismantling may also comprise the removal of larger plastic components, such as bumpers, dashboard, fluid containers for recycling the plastics separately.The ASR may comprise further waste from other sources. For examples, garbage from the last owners may remain in the trunk or interior of the vehicles. The advantage of the present process is that it can handle broadly varying compositions of the ASR.The shredding can be made with a vehicle shredder machine. Vehicle shredder machines are manufactured in different sizes. Typically, a vehicle shredder machine comprises a heavy fast-turning rotor, which may revolve in avertical or a horizontal plane and is often equipped with swinging hammers. The vehicle shredder machine tears and shreds the car hulk until its parts are reduced to fragments. Then the fragments may pass through grids and leave the rotor housing. The automotive shredder residue represents preferably 10 to 40 wt.-%, more preferably from 15 to 35 wt.-%, and most preferably from 20 to 30 wt -% of the original vehicle weightThe fragments are optionally further reduced in size in step a) to obtain the preferred fragment size of at least 90 wt.- % of the shredder residue fragments formed in step a) are smaller than 5 cm, preferably at least 95 wt.-% smaller than 5 cm and more preferably at least 95 wt.-% are smaller than 3 cm. Optional step a) is preferably omitted in case the non-sorted shredder residue NSR has already the preferred fragment size of at least 90 wt.-% of the shredder residue fragments formed in step a) are smaller than 5 cm, preferably at least 95 wt.-% smaller than 5 cm and more preferably at least 95 wt.-% are smaller than 3 cm.The method employed in optional step a) is selected from the group comprising or consisting of shredding, grinding, milling, sieving, classifying and combinations thereof. Optional step a) may further comprise optical and / or manual sorting to remove fragments too large. Such methods are known to the skilled person and can be adapted to a given non-sorted shredder residue NSR to form at least one pre-sorted fraction PSE of end-of-life vehicles which is then provided in step (i).After shredding and further size reduction in optional step a), the metal fragments such as ferrous and non-ferrous metal fragments and non-metallic inorganics (“inerts”) such as glass or sand can be separated from the shredded vehicles in step b). Step b) comprises at least removing metal fragments and / or glass fragments from said nonsorted shredder residue NSR. Metal fragments usually but not always comprise ferrous metal fragments and nonferrous metal fragments.The ferrous metal fragments can be removed by magnetic separators. The magnetic separators utilize typically the magnetic properties of ferrous metals to attract and separate them from non-magnetic materials. Usually, the material is fed onto a conveyor belt or a vibrating feeder, and as the material moves along the conveyor belt, a powerful magnetic field is generated by the magnetic separator (e.g., the magnetic field is created by passing an electric current through a coil, which produces a magnetic force). When the material passes through the magnetic field, the ferrous metals, being magnetic, can be attracted to the magnetic separator. Once the ferrous metals are attracted to the magnetic separator, they can be separated from the rest of the waste material and collected separately. This can be done using a separate chute or conveyor belt to direct the separated ferrous metals to a designated collection area.The non-ferrous metal fragments can be separated from the shredded vehicles by eddy current separators, by density separation methods (e.g., heavy media si nk / float units), by manual sorting and combinations thereof. Suitable eddy current separators exploit the principle of electromagnetic induction to create eddy currents, which in turn generate a magnetic field that repels non-ferrous metals. Usually, the material is fed onto a conveyor belt or avibrating feeder, and as the material moves along the conveyor belt, an alternating magnetic field is generated by the eddy current separator. When the alternating magnetic field interacts with the conductive non-ferrous metals, such as aluminum or copper, it can induce eddy currents within them due to electromagnetic induction. These eddy currents generate typically their own magnetic fields which create a repulsive force that acts against the magnetic field of the eddy current separator. This repulsion may cause the non-ferrous metals to be propelled away from the separator, diverting them from the rest of the material.The automotive shredder residue preferably comprises up to 15 wt.-%, more preferably up to 10 wt -%, and most preferably up to 5 wt.-% of metal fragments, such as ferrous and non-ferrous metal particles. Typically, 60 to 90 wt.- % of the vehicle weight is metal, which can be separated from the shredded vehicle.Non-metallic inorganics ("inerts”) such as glass or sand are preferably separated by density separation. Suitable methods for density separation are cyclone separation, jigging, air separation, or sink-float separation. The automotive shredder residue may comprise preferably up to 15 wt.-%, more preferably up to 10 wt.-%, and most preferably up to 5 wt-% of glass fragments, e.g., broken window glass fragments.The cyclone separation is usually a method used to separate materials based on their density and size using a device called a cyclone. A cyclone typically consists of a cylindrical body with a conical base and an inlet and outlet at the top. The inlet may be tangentially connected to the body, which creates a swirling motion inside the cyclone. As the material spins inside the cyclone, centrifugal force can be generated which may cause the denser and larger particles to move towards the outer wall of the cyclone, while the lighter and smaller particles tend to stay closer to the center.The jigging separation is a method usually used to separate 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 on the bottom. The container can be mounted on a frame with a mechanism that causes it to move up and down. The jig can be filled with water, and a pulsating flow of water is introduced from the bottom of the container. The pulsation may cause the material to move up and down in the container. The denser particles may tend to settle faster and move towards the bottom of the container, while the lighter particles tend to stay near the top.The air separation is often based a stream of air, e g., in an air classifier structure which typically consists of a vertical chamber with an inlet at the bottom and an outlet at the top. The chamber may contain a series of vanes or blades that create a centrifugal force that separates the materials. A stream of air is usually introduced from the bottom of the chamber and the air flow causes the material to move upwards and separates it based on its density. The denser particles often tend to move towards the outer wall of the chamber, while the lighter particles tend to stay closer to the center. The separated materials can be collected at different points of the air classifier.The sink-float separation is usually based on the principle that materials with different densities will behave differently when placed in a fluid medium: Dense materials often sink while less dense materials float. The fluid medium can be a heavy liquid, such as water or a specialized solution, or a finely ground powdered material. The liquid is usually chosen to have a density that is between the densities of the materials to be separatedThe automotive shredder residue comprises fragments of various polymeric vehicle parts comprising at least one polymer selected from polyamides, polyisocyanate polyaddition products, rubber, epoxy resins and polyolefins. Said fragments selected from fragments of bumpers, interior panels, dashboard, cable insulation, electrical insulation, flexible foam seating, foam insulation panels, automotive suspension bushings, electrical potting compounds, car body parts, pillar coverings, spoilers polymer parts coated with automotive paint, wheel covers, gears, bushes, cams, bearings, weatherproof coatings, interior and exterior trims, fuel systems, gear housings, headlamp retainer, engine cover, connector housings, door handles, carburetor components, exterior mirror components, windscreen wiper components, windscreen wiper protective housings, decorative grilles, cover strips, roof rails, window frames, sliding roof frames, antenna cladding covers, front and rear lights, radiator grill and body exterior parts, engine covers, cylinder head covers, intake pipes, cylinder head covers, engine covers, housings for charge air coolers, charge air cooler valves of which preferably at least one member is comprised in the sorted shredder residue SSR.“Contaminated vehicle components” are also suited as first feedstock F1. Such contaminated vehicle components are made from plastic materials and were contaminated by contaminants such as gasoline or diesel because of the yearlong physical and chemical contact between said vehicle parts and the respective contaminants. Contaminated vehicle components are for example gas tanks (made from plastic material such as polyethylene) contaminated with gasoline or diesel (= contaminants). Contaminated vehicle components are preferably dismantled from the respective end-of-life vehicle before shredding of said end-of-life vehicle. The shredded parts of the end-of-life vehicle are defined as automotive shredder residue (ASR), the conversion of ASR into at least one pre-sorted fraction PSE of end-of-life vehicles suited a first feedstock F1 in the process according to the present invention is described above. Accordingly, such contaminated vehicle parts are preferably not comprised in automotive shredder residue (ASR).

Such components can remain in the first feedstock F1 for the gasification process in step (iii) because they can also be converted into raw synthesis gas RSG1 comprising C6-C8 aromatic hydrocarbons.The non-sorted shredder residue NSR and / or the at least one pre-sorted fraction PSE of end-of-life vehicles are / is optionally dried before step (I). The first feedstock F1 is preferably pelletized before provided in step (I).

Such pre-treatment methods are known to the skilled person and can be selected and applied for a given type of coal feedstock. Said coal dust can be alsosubjected to the gasification process in the first gasifier G1 as an optional third feedstock F3 and / or the optional second gasifier G2 as an optional fourth feedstock F4 and thereby further increase the yield of C6-C8 aromatic hydrocarbons comprised in the raw synthesis gas RSG1 and / or the second raw synthesis gas RSG2.Biochar is a type of charcoal that is produced through a process called pyrolysis. Pyrolysis involves heating biomass in the absence of oxygen. Biochar is the solid residue that remains after the pyrolysis process. The production of biochar involves heating the biomass to temperatures ranging from 350 to 700 °C in a pyrolysis reactor. During the pyrolysis process, the absence of oxygen prevents the biomass from burning completely and instead promotes the formation of stable carbon compounds, which make up the biochar. The heating process also drives off volatile organic compounds.Biochar suitable as second feedstock F2 can be made from various types of biomass (including wood), agricultural waste, crop residues, forestry waste, animal manure, and sewage sludge.Wood is preferably provided in form of chips and / or pellets as second feedstock F2.Said optional third feedstock F3 is selected from the group comprising or consisting of biomass, refuse-derived fuel (RDF), textiles, dried sewage sludge, pyrolysis oils made from plastic waste, pyrolysis oils made from end-of-life tires, pyrolysis oils made from biomass, heating oils, vacuum residues, preferably vacuum distillation residues, crude oil residues, heavy crude oils, extra heavy crude oils, tar sand bitumen, visbreaker bottom residues, deasphalter bottom residues, C5 asphalthene fraction, high viscous residues, fuel oils, pyrolysis gasolines, tire pyrolysis oils (TPO), waste oils, used oils, municipal solid waste (MSW), tar oils, natural gas, CO2, and mixtures thereof.Preferably, said optional third feedstock F3 is selected from the group consisting of biomass, refuse-derived fuel (RDF), pyrolysis oils made from plastic waste, pyrolysis oils made from end-of-life tires, pyrolysis oils made from biomass, municipal solid waste (MSW), CO2, and mixtures thereof.The optional at least one third feedstock F3 is optionally pre-treated before step (i) by a method selected from the group comprising or consisting of sorting, sieving, milling, grinding, pyrolysis, torrefaction, metal sorting and combinations thereof.More preferably, said first feedstock F1 is converted in step (ii) together with a second feedstock F2 which is a particulate feedstock having a particle size PS and is selected from the group comprising or preferably consisting of coal, bio char and wood wherein said particle size PS of said second feedstock F2 is at least 3 mm (determined by sieving with sieves having defined mesh sizes), most preferably the first feedstock F1 is converted in step (ii) together with a second feedstock F2 which is a particulate feedstock having a particle size PS and is selected from the group comprising or preferably consisting of coal, bio char and wood wherein said particle size PS of said second feedstock F2 is at least 3 mm (determined by sieving with sieves having defined mesh sizes) and a third feedstockF3 which comprises most preferably RDF. The yield of C6-C8 aromatic hydrocarbons separated from said first liquid residue LR1 in step (iv) is increasing, when converting said first feedstock F1 together with the second feedstock F2 or together with the second feedstock F2 and the third feedstock F3 in step (ii). Furthermore, a steadier production of raw synthesis gas RSG1 is archived by such feedstock combinations (preferably F1 + F2, more preferably F1 + F2 + F3) because fluctuating amounts and / or calorific value of the first feedstock F1 can be balanced by such feedstock combinations.Preferably, at least 10 wt.-% of all feedstocks provided in step (ii) are second feedstock F2 More preferably, at least 15 wt.-% of all feedstocks provided in step (ii) are second feedstock F2. Most preferably, at least 20 wt.-% of all feedstocks provided in step (ii) are second feedstock F2. The remaining portion are the first feedstock F1 and optionally also the third feedstock F3.In step (ii) of the process according to the present invention, said first feedstock F1 comprising at least one presorted fraction PSE provided in step (i) and the second feedstock F2 are converted in a first gasifier G1 into a first raw synthesis gas RSG1 , wherein said first raw synthesis gas RSG1 comprises CO, H2, C6-C8 aromatic hydrocarbons.Optionally, said first feedstock F1 and said second feedstock F2 and a third feedstock F3 are provided in step (i) and converted in step (ii) in a first gasifier G1 into a first raw synthesis gas RSG1, wherein said first raw synthesis gas RSG1 comprises CO, H2, C6-C8 aromatic hydrocarbons.The first feedstock F1 and the second feedstock F2 can be fed into the first gasifier G1 separately or together and thereby converted into a first raw synthesis gas RSG1 , wherein said first raw synthesis gas RSG1 comprises CO, H2, C6-C8 aromatic hydrocarbons. Together includes a) feeding the first feedstock F1 and the second feedstock F2 at the same time into the first Gasifier G1 without pre-mixing the first feedstock F1 and the second feedstock F2 or premixing the first feedstock F1 and the second feedstock F2 before feeding said feedstocks into the first gasifier G1 .In case the first feedstock F1 and the second feedstock F2 are converted in step (ii) together with a third feedstock F3, all three feedstocks can be fed into the first gasifier G1 separately or together (F1 + F2 together and F3 separately or F1 + F3 together and F2 separately or F2 + F3 and F1 separately, or F1 + F2 + F3 together, “feedstock combinations”) and thereby converted into a first raw synthesis gas RSG1, wherein said first raw synthesis gas RSG1 comprises CO, H2, C6-C8 aromatic hydrocarbons. Together includes a) feeding said feedstock combinations at the same time into the first Gasifier G1 without pre-mixing or pre-mixing said feedstock combinations before feeding said feedstocks into the first gasifier G1.The first gasifier G1 is preferably a fixed bed gasifier which is best suited for converting at least one pre-sorted fraction PSE from end-of-life vehicles comprised in the first feedstock F1 and the second feedstock F2 by gasification into C6-C8 aromatic hydrocarbons (comprised in the raw synthesis gas RSG1). More preferably, the fixed bed firstgasifier G1 is a fixed bed dry bottom gasifier or a slagging gasifier. Said gasifier types are even more suited for converting at least one pre-sorted fraction PSE from end-of-life vehicles and the second feedstock F2 by gasification into C6-C8 aromatic hydrocarbons. Slagging gasifiers such as the British Gas / Lurgi gasifier (also known as “BGL” gasifier) require less steam to be fed into the gasifier than other types of fixed bed gasifiers. Thereby, a higher temperature is achieved in the combustion zone of the gasifier and the conversion of the at least one pre-sorted fraction PSE from end-of-life vehicles is further increased. Furthermore, a fixed bed dry bottom gasifier G1 or a slagging gasifier G1 enables a higher throughput of pre-sorted fraction PSE from end-of-life vehicles comprised in the first feedstock F1 because drag out of slag which is formed therefrom during the gasification is simpler than in other types of fixed bed gasifiers G1. Thereby, the yield of desired C6-C8 aromatic hydrocarbons is increased.The content of methane comprised in the raw synthesis gas RSG1 formed in the first gasifier G1 may be higher than desired. Furthermore, side products, referred herein as "condensates” and comprising tar, particularly tar oil may also be produced in said first gasifier G1. Accordingly, in a preferred aspect of the present invention, said condensates, particularly tar oil TO, produced as a side product in the first gasifier G1 are / is then used as a feedstock for a second gasifier G2 which is preferably an entrained flow gasifier. Said condensates, particularly tar oil TO, are / is converted in the second gasifier G2 by a gasification process into a raw synthesis gas RSG2 which preferably comprises methane at a higher concentration than in the raw synthesis gas RSG1. When both raw synthesis gas streams RSG1 and RSG2 are combined, the resulting combined raw synthesis gas RSG12 has a lower methane concentration than the raw synthesis gas RSG1 , which is a desired effect. Furthermore, the yield of 06-08 aromatic hydrocarbons formed by gasification of the first feedstock F1 comprising at least one pre-sorted fraction PSE provided in step (i) is further increased thereby, which is a particularly desired effect.In one aspect of the present invention, "condensates” are formed as a side product during step (ii) in said first gasifier G1 from which condensates preferably tar oil TO is separated in an optional condensate separation unit CSU. Said condensates, preferably said tar oil TO is separated from said condensates are / is then fed as a feedstock into an optional second gasifier G2 which is preferably an entrained-flow gasifier and converted onside said optional second gasifier G2 into a second raw synthesis gas RSG2. Said second raw synthesis gas RSG2 can be combined with the first raw synthesis gas RSG1 before cleaning said first raw synthesis gas RSG1 and said second raw synthesis gas RSG2 in step (iii). Thereby, the yield of C6-C8 aromatic hydrocarbons comprised in the resulting raw synthesis gas streams RSG1 and RSG2 and the clean synthesis gas stream CSG is increased. Furthermore, a higher portion of the at least one pre-sorted fraction PSE from end-of-life vehicles comprised in the first feedstock F1 and provided in step (i) is converted into the desired C6-C8 aromatic hydrocarbons then comprised in the first liquid residue LR1.An overview of gasifiers G, especially entrained flow gasifiers G and plasma gasifiers G is for example provided in James G. Speight, Handbook of Gasification Technology, Scrivener Publishing and Wiley, 2020, chapter 8.4.2, pages 259 to 262.The temperature inside the optional entrained flow gasifier G2 preferably ranges from 1000 to 1500 °C, more preferably from 1100 to 1450 °C and most preferably from 1200 to 1400 °C. The pressure inside said optional entrained flow gasifier preferably ranges from 1 to 55 bar(abs.), more preferably from 5 to 50 bar(abs.) and most preferably from 20 to 45 bar(abs.)Optionally, a fourth feedstock F4 is converted in said optional second gasifier G2 together with said condensates, preferably said tar oil TO separated from said condensates, into raw synthesis gas RSG2. Said optional fourth feedstock F4 is a feedstock which is preferably liquid or gaseous at room temperature or at an elevated temperature such as 80 °C.Said optional fourth feedstock F4 is more preferably selected from the group comprising or preferably consisting of pyrolysis oils made from plastic waste, pyrolysis oils made from end-of-life tires, pyrolysis oils made from biomass, heating oils, vacuum residues, preferably vacuum distillation residues, crude oil residues, heavy crude oils, extra heavy crude oils, tar sand bitumen, visbreaker bottom residues, deasphalter bottom residues, C5 asphalthene fraction, high viscous residues, fuel oils, pyrolysis gasolines, waste oils, used oils, tar oils from other sources than the first gasifier G1 , natural gas, coal dust, CO2, and mixtures thereof.Optional fourth feedstocks F4 such as bio-based oils and pyrolysis oils are preferably pre-heated and / or pressurized before fed into the optional second gasifier G2. The optional fourth feedstock F4 is preferably pressurized to > 10 bar(abs.), more preferably > 20 bar(abs.) and most preferably > 40 bar(abs.) before fed into the optional second gasifier G2. Suitable means for pre-heating and / or pressurizing the optional forth feedstock F4 for feeding into the optional second gasifier G2 are known in the art, comprise for example flaps and locks but also annual gaps as part of a burner such as in twin fluid atomizers, pressure nozzles and pressure atomizers, and can be adapted to a given fourth feedstock F4 and / or second gasifier G2 type by the skilled person.Optional addition of a fourth feedstock F4 is preferred because thereby the desired constant operation conditions in said entrained flow gasifier G2 can be better maintained and the desired C6-C8 aromatic hydrocarbons and raw synthesis gas RSG2 having the desired molar ratio CO : H2 is formed.Preferably, the tar oil TO and the optional fourth feedstock F4 are fed into the entrained flow gasifier G2 via at least one burner whereby said at least one burner comprises one annular gap for the tar oil TO and a separate annular gap through which the optional fourth feedstock F4 is fed. Steam, preferably mixed with oxygen is co-fed into the entrained flow gasifier G2 through a separate annular gap in said at least one burner.A fourth feedstock F4 is preferred for a stable operation of the optional second gasifier G2 in case the amount of tar oil TO provided as a side product of the first gasifier G1 falls below a critical value. Preferably, said optional fourth feedstock F4 is co-fed into the optional second gasifier in case the minimum feedstock load (about 25 to 30 % of the optimum feedstock load of a given second gasifier G2) is reached or be lower because of insufficient tar oil TOsupply from the first gasifier G1. Said minimum feedstock load is required for a stable operation of and synthesis gas production in said optional second gasifier G2.In step (ill) of the process according to the present invention, said C6-C8 aromatic hydrocarbons comprised in the first raw synthesis gas RSG1 and / or the raw synthesis gas RSG2 in case an optional second gasifier G2 is also used, are removed from said first raw synthesis gas RSG1 and / or said raw synthesis gas RSG2.In principle, C6-C8 aromatic hydrocarbons can be removed from the raw synthesis gas RSG1 and / or RSG2 by different gas cleaning process such as condensation, absorption (chemical absorption and / or physical separation), adsorption, filtration (e.g., membrane filtration). The skilled person can select from such processes and adapt the selected process to a specific raw synthesis gas composition and other parameters.C6-C8 aromatic hydrocarbons can be condensed from raw synthesis gas by cooling down said raw synthesis gas below the boiling point of the individual components of said C6-C8 aromatic hydrocarbons. Thereby, the C6-C8 aromatic hydrocarbons become liquid and the remaining portions of the raw synthesis gas, (CO, H2 and other gases) stay in the gas phase. Thereby, C6-C8 aromatic hydrocarbons can be separated from raw synthesis gas.Adsorption methods such as solid bed adsorption involve the use of specialized adsorbents, such as activated carbon, zeolites, or molecular sieves, to remove 06-08 aromatic hydrocarbons from raw synthesis. The raw synthesis gas is passed through a bed of adsorbent material, which selectively adsorbs 06-08 aromatic hydrocarbons while allowing the clean synthesis gas to pass through. The adsorbent is preferably periodically regenerated by heating or purging with an inert gas to release the captured acid gases. The selection of the appropriate adsorbent (e.g., activated carbon, zeolites, or molecular sieves) for the removal of 06-08 aromatic hydrocarbons depends on factors such as the specific composition of the raw synthesis gas RSG1 and / or RSG2, the required purity levels, and the economics of the process. The regeneration of the adsorbent material is also an important consideration, as it affects the overall cost and environmental impact of the process.Membrane separation is a technology that utilizes selective permeable membranes to separate C6-C8 aromatic hydrocarbons from raw synthesis based on size, solubility, or diffusivity For example, gases such as CO, H2, being smaller molecules, can be selectively permeated through the membrane, while the C6-C8 aromatic hydrocarbons are retained This method offers advantages such as simplicity, compactness, and low energy requirements.Preferably, said C6-C8 aromatic hydrocarbons comprised in the first raw synthesis gas RSG1 and / or the raw synthesis gas RSG2 in case an optional second gasifier G2 is also used, are separated from said first raw synthesis gas RSG1 and / or said raw synthesis gas RSG2 by a gas cleaning process GC in a gas cleaning unit GCU, wherein said first raw synthesis gas RSG1 and / or said raw synthesis gas RSG2 is contacted with at least one washing liquid WL, whereby a clean first synthesis gas CSG and a first liquid residue LR1 are formed, wherein said first liquid residue LR1 comprises C6-C8 aromatic hydrocarbons.The at least one washing liquid WL separates CO2 and C6-C8 aromatic hydrocarbons comprised in the first raw synthesis gas RSG1 and / or the raw synthesis gas RSG2 therefrom, whereby C6-C8 aromatic hydrocarbons are absorbed (chemically and / or physically absorbed) by the at least one washing liquid WL. Optionally further components other than CO and H2 such as sulfur oxides which may be comprised in the first raw synthesis gas RSG1 and / or the raw synthesis gas RSG2 are / is separated therefrom.Preferred gas cleaning process GO with at least one washing liquid WL in the gas cleaning unit GCU comprise amine scrubbing. Amine scrubbing, also known as amine gas treating or gas sweetening, is a suitable gas cleaning process GO for acid gas removal and separation of C6-C8 aromatic hydrocarbons from raw synthesis gas RSG1 and / or RSG2. In this process, raw synthesis gas is brought into contact with a solution of amines and / or alkanolamines, such as monoethanolamine (MEA) or diethanolamine (DEA). The amine and / or alkanolamine solution reacts with the acid gases, selectively absorbing and removing them from the raw synthesis gas. Furthermore, C6-C8 aromatic hydrocarbons comprised in the raw synthesis gas are condensed from said raw synthesis gas and thereby separated therefrom. The loaded amine and / or alkanolamine solution is then regenerated by heating, releasing the captured acid gases for further processing or disposal. Furthermore, the unipolar C6-C8 aromatic hydrocarbons are separated as a liquid phase LP1 from the more polar at least one washing liquid WL forming a liquid phase LP2 and can then be separated by standard methods for separating immiscible liquid phases from each other, e.g., by gravitation in a settler unit. Such separation methods are known to the skilled person and can applied accordingly to a given separation problem.Preferred gas cleaning process GC with at least one washing liquid WL in the gas cleaning unit GCU further comprise physical solvent absorption methods such as the Selexol™ which utilizes a mixture of dimethylethers of polyethyleneglycol as washing liquid WL and the Rectisol® process which utilizes methanol as washing liquid WL. In general, such alcohols and / or ethers are suited as washing liquid WL in such physical solvent absorption methods. Such washing liquids WL have a high affinity for C6-C8 aromatic hydrocarbons and can selectively absorb them from the first raw synthesis gas RSG1 and / or the raw synthesis gas RSG2.In another preferred gas cleaning process GC with at least one washing liquid WL in the gas cleaning unit GCU is disclosed in WO 2018 / 208144 A1. In said, the first raw synthesis gas RSG1 and / or the raw synthesis gas RSG2 is contacted with a washing liquid WL in step (a), at a temperature of 15-250 °C, to obtain a clean first synthesis gas CSG, which is depleted in C6-C8 aromatic hydrocarbons, and a first liquid residue LR1 wherein the C6-C8 aromatic hydrocarbons are dissolved. The first liquid residue LR1 is preferably stripped in step (b) with a stripping gas comprising at least 50 Vol.-% steam, to obtain a stripped washing liquid WL which is advantageously reused in step (a) and a loaded stripping gas comprising the aromatic compounds. The aromatic compounds are separated from the loaded stripping gas in an aromatic hydrocarbon extraction unit AEU for example by condensation of the steam and / or the aromatic compounds comprised in the loaded stripping gas to obtain an immiscible composition andisolating the C6-C8 aromatic hydrocarbons therefrom. The washing liquid WL comprises or consists of organic polysiloxanes, preferably organic polysiloxanes comprising aryl groups.Preferably, the at least one washing liquid WL is selected from the group comprising amines, alkanolamines, alcohols, ethers, organic polysiloxanes, and mixtures thereof. More preferably, the at least one washing liquid is selected from the group consisting of amines, alkanolamines, alcohols, ethers, organic polysiloxanes, and mixtures thereof. Most preferably, the at least one washing liquid is selected from the group consisting of monoethanolamine, diethanolamine, methanol, dimethylethers of polyethyleneglycol, organic polysiloxanes comprising aryl groups, and mixtures thereof.In step (iv) of the process according to the present invention, said C6-C8 aromatic hydrocarbons are separated from said first liquid residue LR1 in an aromatic hydrocarbon extraction unit AEU which is downstream of the gas cleaning unit GCU and in which a C6-C8 aromatic hydrocarbon-rich stream AS is separated from said first liquid residue LR1. The remaining portion of said first liquid residue LR1 leaves said aromatic hydrocarbon extraction unit AEU and is depleted in C6-C8 aromatic hydrocarbons.Preferably, C6-C8 aromatic hydrocarbons comprised in stream AS are preferably further separated in said aromatic hydrocarbon extraction unit AEU into a stream ASa which is enriched in benzene, a stream ASb which is enriched in toluene, a stream ASc which is enriched in C8 aromatic hydrocarbons (ethylbenzene, 1 ,2-xylene, 1 ,3-xylene, 1 ,4- xylene) and said second liquid residue LR2 which is depleted in C6-C8 aromatic hydrocarbons. 1 ,4-Xylene can then be separated from stream ASc by standard methods knwon in the art such as distillation.The aromatic hydrocarbon extraction unit AEU can be any unit operation suitable to separate C6-C8 aromatic hydrocarbons comprised in the first liquid residue LR1 into a stream AS and a second liquid residue LR2 and / or a stream ASa, a stream ASb, a stream ASc and said second liquid residue LR2. For example, the aromatic hydrocarbon extraction unit AEU can comprise at least one selective adsorption unit operation, at least one selective absorption unit operation, at least one extractive distillation unit operation, at least one solvent extraction followed by distillation and combinations thereof. Suitable solvents for extraction comprise solvents having a higher boiling point than C6-C8 aromatic hydrocarbons such as N-methylpyrrolidone and morpholine.Suitable aromatic hydrocarbon extraction units AEU are commercially available, for example the Morphylane® extractive distillation process by Uhde, Sulfolan® process by Shell-UOP (using tetrahydrothiophene dioxide as extraction solvent), Arosolvan® process by Lurgi (using N-methylpyrrolidone as solvent), Morphylex® process by Krupp-Koppers (using N-formylmorpholine as solvent), Formex® process by Snamprogetti (using N-formylmorpholine as solvent), IFP process by IFP (using dimethyl sulfoxide as solvent) and Mofex® process by Leunawerke (using methylformamide as solvent).The stream ASa preferably comprises at least 90 wt.-% benzene, more preferably at least 95 wt.-% benzene and most preferably at least 99 wt.-% benzene. The stream ASb preferably comprises at least 90 wt.-% 1- methylbenzene, more preferably at least 95 wt.-% 1 -methylbenzene and most preferably at least 99 wt.-% 1- methylbenzene. The stream ASc preferably comprises at least 90 wt.-% of xylene isomers, more preferably at least 93 wt.-% of xylene isomers. “Xylene isomers” comprise 1,2-xylene, 1,3-xylene and 1,4-xylene.The C6-C8 aromatic hydrocarbons comprised in the first liquid residue LR1 can also be separated therefrom in an aromatic hydrocarbon extraction unit AEU by the following steps: a) contacting the first liquid residue LR1 with a stripping gas SG, said stripping gas, preferably comprising at least 50 Vol.-% steam, to obtain a loaded stripping gas LGS, said loaded stripping gas LGS comprising C6-C8 aromatic hydrocarbons separated from said first liquid residue LR1 and a stripped washing liquid WL previously comprised in said first liquid residue LR1 and b) separating the C6-C8 aromatic hydrocarbons from the loaded stripping gas LSG formed in step a) by condensation of the C6-C8 aromatic hydrocarbons comprised in the loaded stripping gas LSG therefrom.Optionally, the one or both streams ASb and / or ASc are then fed into a hydroalkylation unit HAU whereby toluene and / or xylene isomers and / or ethylbenzene are converted into benzene. Accordingly, the benzene yield can be increased thereby. Hydroalkylation of alkyl-substituted benzene-derivatives into benzene and corresponding hydroalkylation units HAU are known in the art and are for example described in Ullmann's Encyclopedia of Industrial Chemistry, Vol. 5, Chapter “Benzene” by H. O. Folkins, pages 246-251, 2012 and in Industrielle organische Chemie, 3rdEd., K. Weissermel, H.-J. Arpe, pages 351 -352, 1988 which are both incorporated by reference herein.Next, the C6-C8 aromatic hydrocarbons separated from the first liquid residue LR1 are provided in step (a) and converted into at least on monomer M in step (b). Said monomer M is preferably selected from the group comprising or preferably consisting of azepan-2-one, hexanedioic acid, benzene-1 ,4-dicarboxylic acid, 1 ,1 '-methylenebis(4- isocyanatobenzene), 2-isocyanato-1 -methylbenzene, 3-isocyanato-1-methylbenzene, 4-isocyanato-1- methylbenzene, 2,4-diisocyanato-1-methylbenzene, 2,6-diisocyanato-1-methylbenzene and styrene.Benzene separated in step (iv) is preferably converted in step (b) into a monomer M selected from the group comprising or preferably consisting of azepan-2-one, hexanedioic acid, and 1 ,1 '-methylenebis(4- isocyanatobenzene).1 -Methylbenzene separated in step (iv) is preferably converted in step (b) into a monomer M selected from the group comprising or preferably consisting of 2-isocyanato-1 -methylbenzene, 3-isocyanato-1 -methylbenzene, 4-isocyanato- 1 -methylbenzene, 2,4-diisocyanato-1-methylbenzene, 2,6-diisocyanato-1-methylbenzene and styrene.1 ,4-Xylene separated in step (iv) as stream ASc or from stream ASc in a further step (e.g., by distillation) is preferably converted in step (b) into the monomer M benzene-1 ,4-dicarboxylic acid.Ethylbenzene optionally separated in step (iv) is preferably converted in step (b) into monomer M styrene by methods known in the art.Benzene can be converted into azepan-2-one or hexanedioic acid in step (b) of the process according to the present invention by the following method: First, benzene separated in step (iv) from the first liquid residue LR1 (e.g., from stream ASa) is provided in step (a) and reacted with hydrogen. Hydrogen from standard sources used in chemical plants can be used. Preferably, the hydrogen or at least a portion thereof is “green hydrogen”, generated for example by electrolysis of water using electricity generated from renewable energy sources (e.g., solar energy, wind energy, tidal energy, and nuclear energy) and / or low-carbon energy sources and / or a methane pyrolysis, preferably a methane pyrolysis using at least partially methane from a renewable source. Methane from a renewable source comprises biomethane. Next, the benzene provided in step (a) and hydrogen are contacted with each other in the presence of a first heterogeneous catalyst whereby cyclohexane is formed. Cyclohexane can be manufactured by a hydrogenation reaction from said benzene by a catalytic hydrogenation reaction in the presence of hydrogen. Suitable catalysts comprise nickel, platinum, or palladium on a support such as alumina, or a Raney nickel catalyst. The process temperature is about 300 °C or less at a pressure of about 20 to about 30 MPa. Further details are for example disclosed in M. L. Campbell, Ullmann's Encyclopedia of Industrial Chemistry, Vol. 11 , Chapter “Cyclohexane”, pages 44 to 46, 2011 and the references cited therein.Next, the cyclohexane is oxidized in the presence of oxygen and, optionally, a second heterogeneous catalyst, whereby cyclohexanone is formed. Cyclohexanone can be manufactured from cyclohexane for example by liquidphase oxidation in the presence of air in an uncatalyzed or catalyzed reaction (e.g., cobalt catalyst as second heterogeneous catalyst) at a temperature in the range of about 140 to about 180 °C and a pressure in the range of 0.8 to about 2 MPa. Cyclohexanone can also be manufactured from cyclohexane in the presence of anhydrous (meta-)boric acid. Cyclohexanol is produced by such processes as a side product. Such mixtures comprising cyclohexanone and cyclohexanol are also known as “KA oil” (“ketone-alcohol oil”) and “AnoIon”. Suitable manufacturing processes for cyclohexanone from cyclohexane such as the above discussed ones are for example disclosed in M T. Musser, Ullmann's Encyclopedia of Industrial Chemistry, Vol. 11, Chapter “Cyclohexanol and Cyclohexanone”, pages 51 to 54, 2011 and the references cited therein.Azepan-2-one is then formed from cyclohexanone by converting cyclohexanone to cyclohexanone oxime and then converting the cyclohexanone oxime into azepan-2-one. Azepan-2-one (caprolactam) is manufactured from cyclohexanone via cyclohexanone oxime as an intermediate. Next, cyclohexanone oxime is subjected to a Beckmann rearrangement by which azepan-2-one is formed. Cyclohexanone oxime can be for example formed from cyclohexanone in the presence of ammonium hydroxylammonium sulfate or by an ammoximation of cyclohexanone in the presence of ammonia and hydrogen peroxide. Azepan-2-one can be formed from cyclohexanone oxime by a Beckmann rearrangement. The Beckmann rearrangement reaction can be performed in the presence of a catalyst either in liquid phase or gas phase. For example, fuming sulfuric acid or oleum is used as a catalyst in liquid phaseBeckmann rearrangement followed by a neutralization reaction and separation of the azepan-2-one which is then purified in further process steps. Such manufacturing methods for azepan-2-one from cyclohexanone are for example disclosed in J. Tinge, M. Groothaert, H. o. h. Veld, J. Ritz, H. Fuchs, H. Kieczka, W. C. Moran, Ullmann's Encyclopedia of Industrial Chemistry, Chapter “Caprolactam", pages 4 to 16, 2018 and the references cited therein.Hexanedioic acid can be manufactured from cyclohexanone by oxidation in the presence of nitric acid, for example at temperature between about 60 to 80 °C and a pressure of about 0 1 to about 0.4 MPa in the presence of a coppervanadium catalyst Optionally, a second reactor operating at a temperature from about 110 to about 120 °C is added to the process. Next, nitrogen oxides are removed with air and nitric acid is recovered from such mixtures.Hexanedioic acid can then be separated by crystallization and purified by recrystallization. Suitable manufacturing processes for hexanedioic acid cyclohexanone are for example described in M.T. Musser, Ullmann’s Encyclopedia of Industrial Chemistry, Vol. 11, Chapter “Adipic Acid”, pages 2 to 5, 2005 and the references cited therein.Isocyanate derivatives of benzene and 1 -methylbenzene which are suitable as monomers M for the manufacture of polymers P can be manufactured in step (b) from benzene and 1 -methylbenzene separated in step (iv) from the first liquid residue LR1 (e.g., from stream ASb) as follows:In step (b) of the process according to the present invention, benzene or 1 -methylbenzene is contacted with the mixture of nitric acid and sulfuric acid whereby nitrobenzene or a nitro-derivative of 1 -methylbenzene is formed, wherein the nitro-derivative of 1 -methylbenzene is preferably selected from the group consisting of 2-nitro-1- methylbenzene, 3-nitro1 -methylbenzene, 4-nitro1-methylbenzene, 2,4-dinitro1 -methylbenzene, 2,6-dinitro1- methylbenzene and mixtures thereof. Benzene or 1 -methylbenzene are converted to nitrobenzene or (di)nitro derivatives of 1 -methylbenzene by direct nitration in liquid phase using a mixture of nitric acid and sulfuric acid (“nitrating acid"). The nitration reaction can be made by an isothermal reaction at a temperature of about 50 to about 100 °C and ambient pressure in a cascade of reactors (stirred cylindrical or tubular) or by an adiabatic reaction in a cascade of stirred reactors or a jet impingement reactor at a temperature in the range of about 90 to about 190 °C and ambient pressure or increased pressure such as 1.5 bar, 2 bar or even higher pressure such as 5 bar or 10 bar.Next, the nitrobenzene or nitro-derivative of benzene or 1 -methylbenzene, preferably the mono-nitro-derivatives of the aforementioned, is hydrogenated in the presence of hydrogen and, optionally, a catalyst, whereby aniline or an amino-derivative of 1 -methylbenzene is formed, wherein the amino-derivative of 1 -methylbenzene is preferably selected from the group consisting of 2-amino-1 -methylbenzene, 3-amino-1 -methylbenzene, 4-amino-1- methylbenzene, 2, 4-amino-1 -methylbenzene, 2,6-amino-1-methylbenzene and mixtures thereof. Aniline is manufactured from benzene via nitrobenzene, (di)amino-derivatives of 1 -methylebenzene are manufactured via (di)nitro-l -methylbenzene derivatives manufactured from 1 -methylbenzene.

First, two equivalents of aniline are condensed with formaldehyde, preferably in the presence of hydrochloric acid as a catalyst, to form the diamine precursor 1 ,1 '-methylenebis(4- ami nobenzene). Next, 1 ,1 '-methylenebis(4-aminobenzene) is phosgenated with phosgene to form different isomers of 1,1 '-methylenebis(isocyanatobenzene). The phosgenation of 1,r-methylenebis(4-aminobenzene) can be for example made in liquid phase using an aromatic solvent in a batch process or a continuous process. The desired 1, 1 '-methylenebis(4-isocyanatobenzene) is then separated from the phosgenation reaction products by a continuousthin-film distillation and / or by crystallization. Both processes are known as "splitting" (or, respectively, the equipment known as "splitters"). In addition to 1,1 '-methylenebis(isocyanatobenzene) also condensation products thereof can be formed thereby which are poly-isocyanate derivatives of benzene. The residual crude product which comprises or consists of oligomeric 1,1 '-methylenebis(4-isocyanatobenzene) can be for example used for manufacture of rigid polyurethane or polyisocyanurate foams. The residual crude product is for example marketed as polymeric 1, 1 '- methylenebis(4-isocyanatobenzene) (“PMDI”, poly-isocyanate derivatives of benzene) and contains, next to a residual level of monomers, oligomers and polymers of 1, 1 '-methylenebis(4-isocyanatobenzene) with a broader distribution of chain lengths.

The phosgenation of (di)amino derivatives of benzene and 1- methylbenzene can be for example made in liquid phase using an aromatic solvent in a batch process or a continuous process. The desired di- and / or poly-isocyanate derivative of benzene and 1 -methylbenzene is then for example separated from the phosgenation reaction products by a continuous thin-film distillation and / or by crystallization. Both processes are known as "splitting" (or, respectively, the equipment known as "splitters").
