Charles F. Lochow has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hydrocarbon cracking catalyst
    Patent number: 4793827
    Abstract: A hydrocarbon cracking catalyst comprises rare earth exchanged "Y" zeolite which has been ion exchanged to enhance the yttrium content. The catalyst is employed in fluid catalytic cracking to maximize gasoline.
    Type: Grant
    Filed: February 24, 1987
    Date of Patent: December 27, 1988
    Assignee: Ashland Oil, Inc.
    Inventors: Charles F. Lochow, Daniel B. Kovacs
  • Hydrocarbon cracking with yttrium exchanged zeolite Y catalyst
    Patent number: 4664780
    Abstract: A hydrocarbon cracking catalyst comprises rare earth exchanged "Y" zeolite which has been further ion exchanged to enhance the yttrium content. The catalyst is employed in a fluid catalytic cracking process to maximize gasoline.
    Type: Grant
    Filed: November 1, 1985
    Date of Patent: May 12, 1987
    Assignee: Ashland Oil, Inc.
    Inventors: Charles F. Lochow, Daniel B. Kovacs
  • Passivation of vanadium accumulated on catalytic solid fluidizable particles
    Patent number: 4515683
    Abstract: Passivation of vanadium accumulated on catalyst, e.g. crystalline zeolite hydrocarbon conversion catalyst in the rare earth and/or ammonia exchanged zeolite form, effectively minimizes the degrading characteristics of accumulated vanadium on the catalyst. The passivation is accomplished by impregnating or, preferable, precipitating, rare earths, e.g. lanthanum, onto the catalyst particles before and/or after vanadium accumulation. The process is also applicable to inert sorbent particles, e.g. those used for removing carbon and metals from contaminated hydrocarbons.
