  • Conversion of hydrocarbons to olefins
    Patent number: 4247386
    Abstract: A catalytic process for hydrocracking C.sub.5.sup.+ hydrocarbons or mixtures thereof into a C.sub.2 -C.sub.5 mixture paraffin stream in the presence of a palladium/Group IIA, e.g. Be Mg, or IIIB, e.g. Sc, Y, ZSM-20 hydrocracking catalyst, and thermally cracking this mixture to recover ethylene and propylene.
    Type: Grant
    Filed: August 6, 1979
    Date of Patent: January 27, 1981
    Assignee: Mobil Oil Corporation
    Inventors: Rene B. LaPierre, Vern W. Weekman
  • Crystalline zeolite catalysts of chemical reactions
    Patent number: 4197214
    Abstract: Crystalline zeolite catalysts are stabilized against reducing and moisture containing atmospheres by providing and maintaining substantial metal cationic sites in the zeolite during use in chemical reactions encountering reducing and/or moisture rich atmospheres at high temperature.
    Type: Grant
    Filed: October 10, 1978
    Date of Patent: April 8, 1980
    Assignee: Mobil Oil Corporation
    Inventors: Nai Y. Chen, William J. Reagan, Vern W. Weekman, Jr.
  • Combustion regeneration of hydrocarbon conversion catalyst with recycle of high temperature regenerated catalyst
    Patent number: 3970587
    Abstract: A fluid catalytic cracking - catalyst regeneration system is described wherein regeneration of a crystalline zeolite hydrocarbon conversion catalyst is accomplished at an elevated temperature in the presence of regenerated catalyst mixed therewith in the upper portion of a bed of regenerated catalyst with the mix ratio controlled as a function of the amount of primary regeneration gas introduced to a lower portion of the bed of regenerated catalyst.
