Publication number: 20240132425Abstract: Catalytic compositions and processes for depolymerizing polyolefin-based feed into useful petrochemical products are described. The compositions are a composite of a zeolite catalyst component and a co-catalyst comprising an activated clay component and/or a solid base component. These catalyst systems, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of impurities that may be present in the polyolefin-based feed. This results in a shorter residence time in the depolymerization unit and more efficient process.Type: ApplicationFiled: October 23, 2023Publication date: April 25, 2024Applicant: Basell Poliolefine Italia S.r.l.Inventors: Sandor Nagy, Christopher D.

Publication number: 20230009131Abstract: Pre-treatment methods for polyolefin-based feed streams before depolymerization are described. Polyolefins are separated from other material in the polyolefin-based feed stream using density differences in an aqueous solution, which allows for a pre-treatment method that does not affect the depolymerization catalyst. By removing the non-polyolefin materials from the feed stream, the depolymerization of the polyolefin material can proceed at lower temperatures for longer cycles. This results in a more efficient process with a smaller carbon footprint.Type: ApplicationFiled: July 8, 2022Publication date: January 12, 2023Applicant: Basell Poliolefine Italia S.r.l.Inventors: Sandor Nagy, Diego Brita, Christopher D.

Patent number: 11377534Abstract: Methods of depolymerizing polyolefin-based material into useful petrochemical products using metal oxides and heat are described. The metal oxides improve the depolymerization reaction by decreasing the onset temperature for the depolymerization, which results in a higher depolymerization rate and a shorter residence time in the depolymerization unit, allowing for a predictable depolymerization reaction, and decreasing the branching or aromatic formations in the product.Type: GrantFiled: September 9, 2020Date of Patent: July 5, 2022Assignee: Basell Poliolefine Italia S.r.l.Inventors: Diego Brita, Sheri E.
