  • Polyolefin depolymerization with metal oxides
    Patent number: 11377534
    Abstract: 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: Grant
    Filed: September 9, 2020
    Date of Patent: July 5, 2022
    Assignee: Basell Poliolefine Italia S.r.l.
    Inventors: Diego Brita, Sheri E. Davis, Yulenty Deal, Simona Guidotti, Dario Liguori, Sandor Nagy, Christopher D. Smith, Daniel F. White, Xueyong Yang, Shahram Mihan
