  • Isomerization process for upgrading low-octane light paraffinic feeds using a chlorided platinum-alumina-rhenium catalyst
    Patent number: 4241231
    Abstract: Isomerizable light paraffinic hydrocarbon feeds are isomerized in an improved process using a particular super-chlorided reforming catalyst under isomerizing conditions. A chloride source in the feed stabilizes the catalyst. This process provides for a material octane improvement of the feed without excessive loss thereof to normally gaseous hydrocarbons.

  • Sorbent regeneration in a process for removing sulfur-containing impurities from mineral oils
    Patent number: 4179361
    Abstract: Mineral oils containing minor or residual amounts of sulfur-containing impurities are upgraded by contact thereof with a cobalt oxide-supported sorbent under sulfur-sorbing conditions. The sorbent is regenerated by a set of sequential treatment steps.
    Type: Grant
    Filed: November 13, 1978
    Date of Patent: December 18, 1979
    Assignee: Chevron Research Company
    Inventor: Manfred J. Michlmayr
  • Upgrading metal-contaminated petroleum oils containing vanadium and/or nickel
    Patent number: 4039432
    Abstract: A petroleum oil containing, in parts by weight, at least 10 parts of vanadium and/or nickel per million parts of the oil is upgraded by contacting the oil in the liquid phase with an aqueous solution of at least one extraction agent of the group ferric salts soluble in acidified water and stannic chloride. The aqueous solution must have a pH at least sufficiently acidic to inhibit precipitation of the agent as hydroxide or basic salt.
