Abstract: A method for preparing a hydrocracking catalyst comprising: (i) providing a shaped body comprising a zeolite and a binder, wherein the shaped body has been obtained by shaping, calcination and cooling, wherein the zeolite is ZSM-5 having a silica (SiO2) to alumina (Al2O3) molar ratio of 25-75; (ii) optionally drying the shaped body at a temperature of 100-300° C. for a period of at least 1 hour; (iii) depositing a hydrogenation metal on the shaped body by an impregnation for a period of at most 2 hours such that the amount of the hydrogenation metal is 0.010-0.30 wt % with respect to the total catalyst; (iv) optionally rinsing the metal deposited shaped body with water; and (v) heat-treating the metal deposited shaped body in air at a temperature of 250-300° C. for a period of 1-5 hours; wherein the catalyst comprises a total of less than 0.05 wt % sodium and cesium.

Abstract: Modular systems and methods for removal of contaminants from a mixed plastic waste pyrolysis oil and optionally processing it in a hydrogenation unit to produce a decontaminated hydrogenated pyrolysis oil. These contaminants include metal compounds and non-metal compounds, such as silica compounds, halogenated compounds, phosphorous compounds, oxygenates, and nitrogenates.

Abstract: A process for processing mixed plastics comprising simultaneous pyrolysis and dechlorination of the mixed plastics, the process comprising contacting the mixed plastics with a zeolitic catalyst in a pyrolysis unit to produce a hydrocarbon product comprising a gas phase and a liquid phase; and separating the hydrocarbon product into a hydrocarbon gas stream and a hydrocarbon liquid stream, wherein the hydrocarbon gas stream comprises at least a portion of the gas phase of the hydrocarbon product, wherein the hydrocarbon liquid stream comprises at least a portion of the liquid phase of the hydrocarbon product, wherein the hydrocarbon liquid stream comprises one or more chloride compounds in an amount of less than about 100 ppmw chloride, based on the total weight of the hydrocarbon liquid stream, and wherein the hydrocarbon liquid stream is characterized by a viscosity of less than about 400 cP at a temperature of 300° C.

Abstract: A process for reducing a chloride content of a hydrocarbon feed stream involving contacting a hydrocarbon feed stream comprising a chloride containing pyrolysis oil obtained by cracking a chloride containing thermoplastic material with a sulfided catalyst comprising at least one of Co, Mo, and Ni or a catalyst comprising Pd, Pt, Cu, and/or Zn on a catalyst support in the presence of hydrogen gas to reduce one or more organic chloride compounds present in the hydrocarbon feed stream and form a hydrocarbon product stream and HCl. The HCl is removed from the hydrocarbon product stream, wherein the hydrocarbon product stream has a lower chloride content than the hydrocarbon feed stream based on the total weight of the chloride and the total weight of the hydrocarbon feed stream.

Abstract: A method for converting lignin to a phenol product, the method comprising contacting a zeolite catalyst with a lignin under reaction conditions sufficient to produce the phenol product at a yield of equal to or greater than about 50%. A method for converting lignin to a mixed phenol product, the method comprising contacting a large-pore zeolite catalyst with a Kraft lignin under reaction conditions comprising a reaction temperature of from about 550° C. to about 850° C. to produce the mixed phenol product at a yield of equal to or greater than about 50%.
