A process for dechlorination of a hydrocarbon stream and/or a hydrocarbon stream precursor comprising introducing the hydrocarbon stream and/or hydrocarbon stream precursor, a first zeolitic catalyst, and a stripping gas to a devolatilization extruder (DE) to produce an extruder effluent, wherein the hydrocarbon stream and/or hydrocarbon stream precursor comprises one or more chloride compounds in an amount of equal to or greater than about 10 ppm chloride, based on the total weight of the hydrocarbon stream and/or hydrocarbon stream precursor, and wherein the extruder effluent comprises one or more chloride compounds in an amount of less than the chloride amount in the hydrocarbon stream and/or hydrocarbon stream precursor.

Dechlorination of mixed plastics pyrolysis oils using devolatilization extrusion and chloride scavengers

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&#xb0; C.

Catalytic process of simultaneous pyrolysis of mixed plastics and dechlorination of the pyrolysis oil

A process for processing plastic waste comprising converting plastic waste to hydrocarbon liquid and a first Cgas; contacting hydrocarbon liquid with a first hydroprocessing catalyst in hydroprocessing unit to yield a second Cgas and a first hydrocarbon product comprising C+ liquid hydrocarbons; introducing the first hydrocarbon product to a first separating unit to produce treated hydrocarbon stream comprising Chydrocarbons and a first heavies stream comprising C9+ hydrocarbons; contacting the first heavies stream with a second hydroprocessing catalyst in hydrodealkylating unit to yield a second hydrocarbon product comprising C+ liquid hydrocarbons and a third Cgas; conveying the second hydrocarbon product to the first separating unit; feeding treated hydrocarbon stream to steam cracker to produce steam cracker product; separating steam cracker product into olefin gas, saturated hydrocarbons gas, aromatics, and a second heavies stream; and conveying the second heavies stream to hydroprocessing unit.
