  • Publication number: 20240140883
    Abstract: Depolymerization processes and systems for converting polyolefin waste and other waste plastic to hydrocarbons, specifically liquid and gaseous depolymerization reaction products. A depolymerization or catalytic pyrolysis process can be conducted on a process feed which includes a polyolefin waste and a hydrocarbon co-feed under depolymerization conditions, including contacting the reactor feed with a depolymerization catalyst such as a zeolite-based catalyst, with the system described herein. The resulting reactor effluent subsequently can be used as feeds or co-feeds for making circular products such as circular ethylene and circular polyethylene.
