Abstract: Systems and methods for processing a plastic are disclosed. The system includes a feeding device in fluid communication with a cracking unit. A feed stream comprising a plastic is depolymerized in the feeding device at a depolymerization temperature to produce a hydrocarbonaceous wax stream. The hydrocarbonaceous wax stream is then cracked in the cracking unit. The cracking is conducted at a cracking temperature that is lower than, or the same as the depolymerization temperature.

Abstract: A process for activating and maintaining a catalyst for use in hydrocracking a hydrocarbon stream includes continuously contacting a hydrocarbon stream with a hydroprocessing catalyst in the presence of hydrogen. Sulphides and chloride compounds in the hydrocarbon stream are used such that the hydroprocessing catalyst has the ability to hydrogenate, dechlorinate, and hydrocrack components of the hydrocarbon stream.

Abstract: Systems and methods for processing a mixed plastic waste feed to produce a hydrogen-rich hydrocarbon product, such as synthetic crude oil or pyrolysis oil, by processing the mixed plastic waste feed through two cracking units. The first cracking unit is operated at a temperature and a residence time sufficient to at least partially depolymerize the plastic polymers in the mixed plastic waste feed to produce a molten oligomers product stream also containing inorganic components from the mixed plastic waste feed and a gas stream. This molten oligomers product stream is further processed in a thermal or a catalytic cracking unit to produce a hydrocarbonaceous stream that is processed to produce the hydrogen-rich hydrocarbon product, such as a synthetic crude oil that can be processed in a refinery or a pyrolysis oil that can be fed to a steam cracker.
