  • Fluidized catalytic cracker with active stripper and methods using same
    Patent number: 8435401
    Abstract: A staged fluidized catalytic cracker and method for cracking a hydrocarbonaceous material includes a plurality of staged reactors that have catalyst particles flowing in series from one reactor to the next and hydrocarbon feed that is delivered in parallel to the reactors. Between each reactor the partially spent catalyst is actively stripped to partially reactivate the catalyst. Once the catalyst is fully spent in the final reactor the catalyst can be oxidatively regenerated.
    Type: Grant
    Filed: January 6, 2009
    Date of Patent: May 7, 2013
    Assignee: Process Innovators, Inc.
    Inventors: A. Lamont Tyler, Vincent J. Memmott, John A. Paraskos, James R. Vemich
