  • Fluid catalytic cracking catalyst for hydrocarbon oil
    Patent number: 11731114
    Abstract: A fluid catalytic cracking catalyst for hydrocarbon oil that is a blend of two types of fluid catalytic cracking catalysts each of which has a different hydrogen transfer reaction activity or has a pore distribution within a specific range after being pseudo-equilibrated. One catalyst is a catalyst containing a zeolite and matrix components, and the other catalyst is a catalyst containing a zeolite and matrix components. This catalyst is composed of the one catalyst and the other catalyst blended at a mass ratio within a range of 10:90 to 90:10.
    Type: Grant
    Filed: July 22, 2019
    Date of Patent: August 22, 2023
    Assignee: JGC CATALYSTS AND CHEMICALS LTD.
