Definitions

  • TITLE PROCESS FOR PURIFYING A PYROLYSIS OIL WITH A VIEW TO ITS VALORIZATION BY STEAM CRACKING
  • the invention relates to the recovery of oils from the pyrolysis of waste, in particular as feedstock for a steam cracking process.
  • the process according to the invention makes it possible in particular to purify the pyrolysis oil resulting from plastic waste of all kinds, whatever their origin.
  • This plastic waste may contain other types of waste in varying proportions, such as lignocellulosic biomass and/or elastomers.
  • Liquid pyrolysis products also called pyrolysis oils
  • pyrolysis oils can however have high levels of undesirable compounds, particularly for use in charge of a steam cracking treatment.
  • undesirable compounds include heteroatoms, in particular oxygen, nitrogen, sulfur, but also halogens and transition metals.
  • Other undesirable compounds include unsaturated hydrocarbon compounds, including aromatics and dienes.
  • Document WO2020/212315 describes a process for recovering aliphatic hydrocarbons from a liquid product of the pyrolysis of plastic waste, in particular a mixture of plastics. This liquid product is subjected to extraction with a solvent making it possible to obtain a raffinate with a reduced content of aromatic hydrocarbons and/or polar compounds by compared to the liquid product.
  • a first object of the invention relates to a process for purifying a pyrolysis oil resulting from the pyrolysis of waste containing plastics, comprising the following steps:
  • a pyrolysis oil containing saturated and unsaturated hydrocarbon compounds and polar compounds comprising at least one heteroatom selected from oxygen, sulfur, nitrogen, a transition metal, an alkali metal, an alkaline-earth metal, a halogen,
  • the process according to the invention makes it possible to extract at least 20% m/m, at least 30% m/m, or even at least 40% m/m or at least 50% m/m of all the polar compounds initially contained in the pyrolysis oil, in particular several polar compounds, in particular those containing oxygen, sulfur, nitrogen, halogens, in particular chlorine, fluorine and bromine, and metals, in particular transition metals, especially iron.
  • the process according to the invention can also make it possible to extract at least 10% m/m of the unsaturated hydrocarbon compounds.
  • the pyrolysis oil treated in the present invention (and supplied during the first stage) is a pyrolysis oil resulting from the pyrolysis of waste comprising plastics.
  • the pyrolysis oil supplied can be a liquid organic phase resulting from the pyrolysis of waste chosen from plastics and at least least one other waste such as biomass, for example chosen from lignocellulosic biomass, paper and cardboard, and/or one or more elastomers.
  • Typical polymers found in plastics are polystyrene (PS), poly(ethylene terephthalate) (PET), polypropylene (PP), acrylonitrile-butadiene-styrene (ABS), polybutylene, poly( butylene terephthalate) (PBT), high and low density polyethylene (PE), halogenated (Cl, F) or not, polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), etc., or the polymers obtained by polycondensation such as polyamides, polyesters, polyesteramides, etc.
  • Elastomers are linear or branched polymers transformed by vulcanization into an infusible weakly cross-linked three-dimensional network and insoluble. They include natural or synthetic rubbers. They can be part of tire-type waste or any other household or industrial waste containing elastomers, natural and/or synthetic rubber, mixed or not with other components, such as plastics, plasticizers, fillers, vulcanizing agent, vulcanization accelerators, additives, etc.
  • Biomass can be defined as an organic plant or animal product. Biomass thus includes:
  • Pyrolysis oils from biomass are produced by depolymerization and fragmentation of the constituent elements of biomass (holocelluloses (cellulose, hemicellulose), lignin), typically under the action of a rapid increase ( ⁇ 2 seconds) in temperature at 450°C-550°C and rapid quenching of intermediate degradation products.
  • Pyrolysis oils from biomass consist of water (typically 10 to 35% m/m) and a complex mixture of oxygenated compounds. Their elementary composition is close to the composition of the starting biomass with in particular a high oxygen content (from 40 to 60% m/m).
  • the pyrolysis oil supplied may then comprise at least 1% m/m of an organic phase resulting from the pyrolysis of one or more of these other wastes, optionally from 1 to 50% m/m, from 2 to 30% m/m or within an interval defined by any two of these limits.
  • the organic phase or phases resulting from the pyrolysis of at least one other waste are organic phases resulting from the pyrolysis of biomass, or comprise at least 50% m/m, 60% m/m or 80% m/ m, preferably at least 90% m/m of one or more organic phases resulting from the pyrolysis of biomass.
  • the pyrolysis oil treated by the process according to the invention comprises polar compounds and optionally unsaturated compounds which are undesirable, in particular for subsequent use of the pyrolysis oil as feedstock for a steam cracker.
  • the unsaturated compounds can be aromatic compounds and gum precursor diolefins. Their presence can lead to instability of the pyrolysis oil over time with, for example, a variation in viscosity, volatility, potential separation of phases, formation of gums. In addition, the presence of rubber causes clogging problems in the installations.
  • the organic compounds comprising heteroatoms can comprise amines, amides, nitriles, esters, ethers, acids, aldehydes, ketones, alcohols.
  • Organic compounds comprising heteroatoms can be aliphatic or aromatic.
  • acids aldehydes (including hydroxy-aldehydes), ketones (including hydroxy-ketones), alcohols (phenols, methanol, ethanol, are present when the treated waste is biomass, in particular lignocellulosic biomass.
  • the extraction solvent is a polar solvent, it can have a higher or lower density than the density of the treated pyrolysis oil.
  • the extraction solvent is also an immiscible solvent in the pyrolysis oil to be purified.
  • the extraction solvent (or a mixture of solvents where appropriate) is immiscible when its recovery rate is greater than or equal to 0.95.
  • This recovery rate is defined as the ratio of the volume of extract to the volume of initial solvent, this extract being a phase containing the solvent, immiscible with the pyrolysis oil, recovered after agitation then decantation of a mixture of one part by volume of solvent with twenty-five parts by volume of the pyrolysis oil to be purified, at atmospheric pressure and at a temperature of 20°C.
  • this recovery rate can be determined by following the following procedure:
  • the polar solvent can contain one or more heteroatoms, in particular chosen from oxygen, sulfur and nitrogen, preferably oxygen.
  • the polar solvent immiscible with the pyrolysis oil to be purified can be chosen from:
  • An acid pH can be obtained by adding one or more organic or inorganic acids.
  • organic acids that can be used include citric acid (C6H 8 O 7 ), formic acid (CH 2 O 2 ), acetic acid (CH 3 COOH), sulfamic acid (H3NSO3).
  • inorganic acids are hydrochloric acid (HCl), nitric acid (HNO3), sulfuric acid (H2SO4), phosphoric acid (H3PO4).
  • glycol ethers including in particular polyethylene glycol with the chemical formula HO-(CH 2 -CH2-O) n -H with a mass-average molar mass of 90 to 800 g/mol, for example diethylene glycol and tetraethylene glycol, polypropylene glycol of chemical formula H[OCH(CH 3 )CH 2 ] n OH with a mass-average molar mass of 130 to 800 g/mol, for example dipropylene glycol and tetrapropylene glycol,
  • dialkyl formamides in which the alkyl group can comprise from 1 to 8 or from 1 to 3 carbon atoms, in particular dimethyl formamide (DMF),
  • furfural for example furfural, 5- (hydroxymethyl)furfural, furfuryl alcohol (2-furanemethanol),
  • - cyclic carbonate esters comprising in particular from 3 to 8 or from 3 to 4 carbon atoms, in particular propylene carbonate and ethylene carbonate.
  • One or more of the aforementioned solvents can be used. However, advantageously, only one of the aforementioned solvents can be used as extraction solvent provided that it is immiscible with the oil to be purified.
  • the extraction solvent can be a glycol ether, in particular polyethylene glycol with the chemical formula HO-(CH 2 -CH 2 -O) n -H with mass mass-average molar mass of 90 to 800 g/mol or polypropylene glycol with the chemical formula H[OCH(CH 3 )CH 2 ] n OH with a mass-average molar mass of 130 to 800 g/mol, or a compound comprising a furan cycle, or a cyclic carbonate ester, in particular propylene or ethylene carbonate, alone or as a mixture, preferably alone.
