Publication number: 20240140883Abstract: 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.Type: ApplicationFiled: October 26, 2023Publication date: May 2, 2024Applicant: Chevron Phillips Chemical Company LPInventors: Cori Demmelmaier-Chang, Mark L.

Publication number: 20240141130Abstract: A tandem polyolefin depolymerization-metathesis process and system for converting polymer waste to smaller hydrocarbons, specifically liquid and gaseous products, which subsequently can be modified and used as feeds or co-feeds for making circular products such as circular ethylene and polyethylene. Specifically, the disclosed processes include a tandem depolymerization process step followed by a metathesis process to provide a effluent that can be separated, further processed with a subsequent depolymerization step, or both. The effluents can be supplied to downstream processing units such as a steam cracker or AROMAX® unit thereby providing an efficient method for converting polymer waste into useful circular products. Therefore, these processes and systems can expand the number of usable plastic waste streams and improve the economics of plastic waste recycling.Type: ApplicationFiled: November 1, 2022Publication date: May 2, 2024Applicant: Chevron Phillips Chemical Company LPInventors: Cori A.
