Definitions
- the present invention relates to the disposal of plastic waste and, more specifically, to a process and apparatus for decomposing plastic material and converting it into hydrocarbons and chemicals of value.
- Plastics are materials widely used by man with various applications, including the manufacture of packaging, packaging, electronics, building materials, textiles, among others. As a result of its intensive use, large quantities of plastic waste are generated, mainly in urban centers. Mexico generates more than 2 million tons per year of plastic waste (INEGI, 201 1) mostly made up of plastics polystyrene (PS), polypropylene (PP), polyethylene (PE, LDPE, HDPE), polyethylene terephthalate (PET) and polyvinylchloride (PVC), which usually have as a destination landfills or outdoor dumps.
- PS polystyrene
- PP polypropylene
- PE polyethylene
- PET polyethylene terephthalate
- PVC polyvinylchloride
- Recycling is usually done by grinding the waste to form pellets, flakes or other small particles with which products such as carpets or coatings
- thermal treatments such as thermal cracking.
- thermal cracking In these it is possible to reverse the polymerization of plastics, breaking chains and releasing monomers.
- chain lengths of the monomers obtained by these techniques are not uniform, so they are not usually useful for the production of new plastic.
- Another disadvantage of thermal cracking is the formation of coke and inorganic coal, which increases the maintenance costs of reactive equipment and adds impurities to the product, in addition to being energy intensive, which represents high operating costs.
- catalytic cracking In order to improve the results of thermal cracking, catalytic cracking arose, which seeks to give some uniformity to the monomers obtained. Catalytic cracking normally occurs in two stages, one consisting primarily of thermal cracking and a second one in which the gaseous products of thermal cracking come into contact with a catalyst, either in a fluidized bed or packed bed reactor. However, two-stage catalytic cracking fails to overcome the formation of inorganic carbon in the reactor and mostly generates low-value waxy products.
- US Patent No. 5,686,066 entitled “Process for recovering phthalic anhydride and hydrogen chloride from plastic materials” discloses a process that employs at least two gasifiers for thermal cracking and two reactors for catalytic cracking. The catalytic cracking reaction is carried out in the gas phase.
- U.S. Patent No. 4,851, 601 entitled “Processing for producing hydrocarbon oils from plastic waste” discloses a two-stage cracking process, the first being thermal cracking in a container with stirring followed by catalytic cracking in a packed bed.
- a ZSM-5 catalyst is used during catalytic cracking, the ZSM -5 has a particle size between 0.1 -10 mm, is used in conjunction with a binder such as alumina, silica or silica-alumina.
- US publication US2010 / 036181 A1 entitled "Conversion of biomass feedstocks into hydrocarbon liquid transportation fuels” discloses a method consisting of gasifying the first matena that contains coal (mainly biomass or methane) to produce syngas, which then reacts through Fischer- Tropsch (FT) to give liquid fuels.
- the method further contemplates a catalytic cracking reactor to convert the resulting long chains of F-T to smaller hydrocarbons and subsequently a hydrogenation reactor to obtain a greater amount of paraffinic hydrocarbons.
- Plastic Material “discloses a process of gasification or partial oxidation in which the matter must necessarily include halogenated compounds (eg, PVC), which results in the production of syngas (CO + H2), halogenated compounds and slag as intermediates.
- halogenated compounds eg, PVC
- US Patent No. 6,866,830 entitled “System for Continuously Preparing Gasoline, Kerosene and Diesel Oil From Waste Plastic” discloses a method consisting of two catalytic reactions: 1) dehydrogenation and decomposition of waste plastics, a catalytic reaction using nickel (metallic catalyst of high price); and 2) fluidized catalytic cracking using a zeolite (solid aluminosilicate acid) as catalyst.
- the method uses steam in fluidized catalytic cracking to remove the oil present in the catalyst particles. It also includes the regeneration of the zeolitic catalyst based on nickel, molybdenum and air.
- Fuel For Conversion Of Waste Material To Liquid Fuel "describes a process that first pyrolizes (passes waste plastics to gas phase) thermally and subsequently the vapors catalytically transforms them in a second step.
- the process includes a carbon remover at the bottom of the pyrolysis chamber This excess carbon is formed by first carrying out the complete thermal pyrolysis and then the catalytic conversion separately.
- the temperature during the catalytic reaction is restricted to a range of 350 to 425 ° C.
- US Publication No. 2012/310023 A1 entitled “Methods Of Producing Liquid Hydrocarbon Fuels From Solid Plastic Wastes” describes a method of producing liquid fuels in which: the waste plastic (solid or molten) is mixed with a metal hydride and a catalyst impregnated with a metal; the mixture is gasified (partial oxidation); and liquid fuels are produced.
- the catalyst substrate can be selected from aluminum oxide, silicon oxide, zeolite, zirconium, magnesium oxide, titanium oxide, activated carbon, clays or a combination.
- the impregnated metal can be selected from: Pt, Pd, Ir, Ru, Rh, Ni, Co, Fe, Mn, Mg, Ca, Mo, Ti, Zn, Al, Pt-Pd alloy, Pt alloy- Ru, Pt-Pd-Ru alloy, Pt-Co alloy, Co-Ni alloy, Co-Fe alloy, Ni-Fe alloy, Co-Ni-Fe alloy or a combination.
- International publication WO 2009/145884 A1 entitled "Method For Converting Waste Plastic To Hydrocarbon Fuel Materials” describes a batch conversion method in which the melting of plastics is carried out in high temperature aerobic atmosphere (370-420 ° C ) to form an aqueous slurry paste and induce thermal cracking.
- the method includes simple distillation of the slurry to generate hydrocarbons and the residue is recycled with the inlet slurry.
- they use a catalyst (mention HZSM-5 commercial zeolite base) that is added to the slurry and recirculated along with the residue.
- a second distillation of the product obtained in the first is performed.
- a disadvantage in the thermal cracking processes of the state of the art is that they require very high temperatures to achieve the decomposition of the polymeric waste material.
- An additional disadvantage of the current processes is that after carrying out the thermal cracking, the steam phase is passed through a bed to perform a catalytic cracking, that is to say in two stages.
- a disadvantage of thermal cracking and catalytic cracking in 2 stages is that higher temperatures ( ⁇ 800 ° C) are required during thermal pyrolysis, and it also has the disadvantage of favoring the formation of coke, which is a low value residue and Contaminant for the catalyst used in the catalytic stage.
- the current depolymerization processes are based on synthetic catalysts and not on the use of natural catalysts such as natural zeolite and / or waste catalysts (giving it a re-use and preventing it from being a contaminant). In addition to that they do not use contaminated waste plastics (for example with oils) because they produce coke or low value products.
- thermo-catalytic to generate hydrocarbons (fuels and chemicals of high value).
- Another object of the present invention is to provide a process and equipment for the production of hydrocarbons by catalytic decomposition of plastic waste in a single step, in which the catalytic cracking in a liquid state requires lower temperatures in order to avoid breaking up chains of Low number of carbons.
- Still another object of the present invention is to provide a process and equipment for the production of hydrocarbons by catalytic decomposition of plastic waste having a more charged distribution of products towards the part of liquids (and if desired, waxes), since the objective Main is the obtaining of fuels and / or liquid chemicals.
- Still another object of the present invention is to provide a process and equipment for the production of hydrocarbons by catalytic decomposition of plastic waste which works at atmospheric pressures and avoids the use of reducing agents.
