  • Desulfurization with improved sorbent regeneration
    Patent number: 6544410
    Abstract: During the regeneration of a sulfurized sorbent comprising zinc aluminate, a promoter metal and zinc sulfide by contact with an oxygen-containing stream to convert at least a portion of said zinc sulfide to zinc oxide the average sulfur dioxide partial pressure in the regeneration zone is controlled within the range of from about 0.1 to about 10 psig to minimize sulfation of the sorbent.
    Type: Grant

    Date of Patent: April 8, 2003
    Assignee: Phillips Petroleum Company
    Inventors: Jason J. Gislason, Ronald E. Brown, Robert W. Morton, Glenn W. Dodwell
  • Desulfurization and sorbents for same
    Publication number: 20030064889
    Abstract: Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a promoter such as nickel, nickel oxide or a precursor of nickel oxide followed by reduction of the valence of the promoter metal in the resulting promoter metal sorbent support composition.
