Abstract: Systems and processes for producing olefins and aromatics. A process can include contacting a first hydrocarbon feed with a catalyst and a hydrogen source under conditions sufficient to produce a used catalyst and an intermediate stream containing olefins and aromatics, and contacting the used catalyst with the intermediate stream and a coke precursor feed to produce a spent coked catalyst and a products stream comprising additional olefins and aromatics.

Abstract: Systems and methods for processing hydrocarbons are disclosed. A crude oil, a crude oil fraction, and/or plastic pyrolysis oil is processed in a low pressure hydroprocessing unit to produce a cracker feed stream. The cracker feed stream is then flowed into a fluid catalytic cracking unit or a stream cracking unit to produce high value chemicals.

Abstract: A process for producing C6 to C8 aromatics and optionally light gas olefins from crude oil and/or pyrolysis oil is disclosed. The process can include hydroprocessing a first stream containing hydrocarbons from the crude oil and/or pyrolysis oil to obtain a second stream containing saturated hydrocarbons having boiling point less than 350° C., separating the second stream to obtain a third stream containing hydrocarbons having boiling point less than 70° C., a fourth stream containing hydrocarbons having boiling point 70° C. to 140° C., and a fifth stream containing hydrocarbons having boiling point greater than 140° C., recycling at least a portion of the fifth stream to the hydroprocessing step, reforming the fourth stream to obtain a sixth stream containing C6 to C8 aromatics, and optionally cracking the third stream to obtain light gas olefins.

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.
