  • Desulfurization catalyst and the catalyst prepared by a method
    Patent number: 4818743
    Abstract: Hydrocarbon conversion catalysts contain at least one Group VIB metal component, at least one Group VIII metal component, and a phosphorus component on a porous refractory oxide and have a narrow pore size distribution including at least about 75 percent of the total pore volume in pores of diameter from about 70 to about 130 angstroms. The catalyst is useful for promoting a number of hydrocarbon conversion reactions, particularly those involving hydrogenative desulfurization.
    Type: Grant
    Filed: December 1, 1987
    Date of Patent: April 4, 1989
    Assignee: Union Oil Company of California
    Inventors: Howard D. Simpson, Ryden L. Richardson, Kenneth Baron
  • Hydrorefining with a regenerated catalyst
    Patent number: 4581129
    Abstract: Deactivated hydrorefining catalysts are regenerated by incorporation of a phosphorus component followed by combustive coke-removal from the catalyst. The regenerated catalyst is useful for promoting hydrodesulfurization reactions, particularly those involving demetallation of hydrocarbons.
    Type: Grant
    Filed: September 17, 1984
    Date of Patent: April 8, 1986
    Assignee: Union Oil Company of California
    Inventors: Richard B. Miller, Ryden L. Richardson
