Abstract: Pyrolysis processes comprise contacting a waste polyolefin with a solid catalyst at a pyrolysis temperature to form a pyrolysis product containing C1-C10 hydrocarbons. In some instances, the solid catalyst can be a silica-coated alumina, a fluorided silica-coated alumina, or a sulfated alumina, while in other instances, the solid catalyst can be any suitable solid oxide or chemically-treated solid oxide that is characterized by a d50 average particle size from 5 to 12 μm and a particle size span from 0.7 to 1.7. Hydrocarbon compositions are formed from the pyrolysis of waste polyolefins with specific amounts of methane and higher carbon number hydrocarbons.

Abstract: A method is provided for producing at least one energy product by catalytically cracking, at a low temperature, a fragmented solid material, without the formation of coke, dioxins and/or furans. A gas atmosphere is maintained at the cracking pressure through gas-exchange communication between the gas atmosphere of the cracking reactor and the gas atmosphere of a device, referred to as a thermochemical vacuum pump, that generates a vacuum pressure formed, by way of a change of state, from an expanded gas state to a condensed liquid state. A second inert oil, referred to as a condensation oil is refluxed at a temperature higher than the evaporating temperature of the condensation oil at the cracking pressure in the thermochemical vacuum pump. The change of state of the condensation oil from the expanded gas state to the condensed liquid state is brought about in the thermochemical vacuum pump in a gas-exchange communication with the gas atmosphere of the cracking reactor and the condensation oil is chosen so that its state-change temperature is at the level of the cracking temperature at the cracking pressure.

Abstract: The present invention relates to a novel process for the preparation of low molecular weight aromatic compounds such as benzene, toluene, and xylenes (BTX) from plastics. Provided is a thermo-catalytic pyrolysis process for the preparation of aromatic compounds from a feed stream comprising plastic, comprising the steps of: a) subjecting a feed stream comprising a plastic to a pyrolysis treatment at a pyrolysis temperature in the range of 600-1000° C. to produce pyrolysis vapors; b) optionally cooling the pyrolysis vapors to a temperature that is below the pyrolysis temperature; e) contacting the vaporous phase with an aromatization catalyst at an aromatization temperature in the range of 450 700° C., which aromatization temperature is at least 50° C. lower than the pyrolysis temperature, in a catalytic conversion step to yield a conversion product comprising aromatic compounds; and d) optionally recovering the aromatic compounds from the conversion product.
