  • Continuous extractive blending process
    Patent number: 4428753
    Abstract: A continuous process for blending isopropanol from an aqueous solution of isopropanol directly into a stream of gasoline blending hydrocarbon by mixing the aqueous solution and the gasoline, rapidly separating the resulting mixture into two phases, for example, by passing it through water coalescer means and recovering the organic phase which consists essentially of the gasoline and isopropanol.
    Type: Grant
    Filed: June 25, 1981
    Date of Patent: January 31, 1984
    Assignee: Chevron Research Company
    Inventor: Susan A. Bezman
  • Diisopropyl ether hydration in isopropanol production
    Patent number: 4405822
    Abstract: A process for producing alcohols by the direct hydration of olefins in which the ether by-product is hydrated with a large molar excess of water in a reaction zone which precedes a propylene hydration reaction zone.
    Type: Grant
    Filed: October 30, 1981
    Date of Patent: September 20, 1983
    Assignee: Chevron Research Company
    Inventor: Susan A. Bezman
  • Process for producing oxygenated fuels
    Patent number: 4403999
    Abstract: A process for producing an oxygenated fuel composition comprising gasoline and isopropanol in which a dilute propylene feedstock is hydrated to produce isopropanol in a single pass, the unreacted olefins are oligomerized to produce gasoline blending stock and the isopropanol is added directly to the gasoline pool from a water-isopropanol azeotropic mixture without the use of energy intensive extractors.
    Type: Grant

  • Oxygenated fuel dehydration
    Patent number: 4374647
    Abstract: A method for dehydrating an oxygenated fuel composition comprising at least one gasoline blending hydrocarbon component, isopropanol and water by contacting the composition with HSPAN.
    Type: Grant
    Filed: June 25, 1981
    Date of Patent: February 22, 1983
    Assignee: Chevron Research Company
    Inventor: Susan A. Bezman
  • Diisopropyl ether reversion and oligomerization in isopropanol production
    Patent number: 4357147
    Abstract: A process for the production of an oxygenated fuel blending composition which contains isopropanol by the hydration of propylene in which the by-product diisopropyl ether is subjected to a reversion reaction and the resulting propylene is oligomerized to form olefinic gasoline.
    Type: Grant
    Filed: October 30, 1981
    Date of Patent: November 2, 1982
    Assignee: Chevron Research Company
    Inventor: Susan A. Bezman
  • Diisopropyl ether reversion in isopropanol production
    Patent number: 4352945
    Abstract: A process for the production of isopropanol by the hydration of propylene in which the by-product diisopropyl ether is subjected to a reversion reaction and the resulting propylene is recycled to the hydration stage.
