  • Mesoporous FCC catalysts with excellent attrition resistance
    Patent number: 10807076
    Abstract: This application discloses a mesoporous catalyst formed by combining a matrix precursor treated with a polyphosphate, and a metallic oxide treated with a cationic electrolyte. The combined treatment with the polyphosphate and cationic polyelectrolyte yields unexpected improvements in attrition resistance, while maintaining high overall pore volume, even as the ratio of meso pore volume to macro pore volume of the formed FCC catalyst increases.
    Type: Grant
    Filed: December 3, 2018
    Date of Patent: October 20, 2020
    Assignee: BASF Corporation
    Inventors: Michael Sigman, Charles Keweshan, Mitchell Willis
