  • Plastics pyrolysis process with quench
    Patent number: 12018212
    Abstract: A plastic catalytic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The catalytic product stream is quenched to below catalytic pyrolysis temperature quickly after exiting the reactor or bulk separation from the catalyst. Quench preserves selectivity of light olefinic monomers. The catalytic pyrolysis process can be operated in a single stage or a two-stage process.
    Type: Grant
    Filed: February 14, 2022
    Date of Patent: June 25, 2024
    Assignee: UOP LLC
