  • Process for catalytic conversion of hydrocarbon feedstock
    Patent number: 4663024
    Abstract: Process for refining hydrocarbon feedstocks comprising contacting a hydrocarbon feedstock with zeolite-containing particles that are free-flowing, discrete, rounded, rigid, frangible, hollow, and opaque. The zeolite-containing particles are essentially completely de-coked upon regeneration, and then retain their catalytic activity even after several cycles of use-regeneration.
    Type: Grant
    Filed: December 31, 1985
    Date of Patent: May 5, 1987
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Paul B. Olson, Richard M. Minday, Julian B. Cooley
  • Hollow zeolite-containing particles useful as refining catalysts
    Patent number: 4546090
    Abstract: Novel zeolite-containing particles. The particles are free-flowing, discrete, rounded, rigid, frangible, hollow, and opaque. The shell or wall of each particle is porous to gases and fluids. The particles are useful as catalysts for refining processes. They are essentially completely de-coked upon regeneration, and they retain their catalytic activity even after several cycles of use-regeneration.
