  • Desulfurization process
    Patent number: 6869522
    Abstract: In a desulfurization process for the removal of organosulfur compounds from a hydrocarbon fluid stream such as cracked-gasoline or diesel fuel wherein a bifunctional sorbent system is employed, surface treatment of the bifunctional sorbent during the use of same for desulfurization results in an extension of the useful life of the bifunctional sorbent prior to the regeneration and reactivation of same for further use in the desulfurization of the hydrocarbon fluid stream.
    Type: Grant
    Filed: April 5, 2002
    Date of Patent: March 22, 2005
    Assignee: ConocoPhillips Company
    Inventors: Gyanesh P. Khare, Bryan W. Cass, Donald R. Engelbert, Edward L. Sughrue, Dennis R. Kidd, Max W. Thompson

  • Transport desulfurization process utilizing a sulfur sorbent that is both fluidizable and circulatable and a method of making such sulfur sorbent
    Patent number: 6274031
    Abstract: A novel circulatable sorbent material suitable for use in a transport desulfurization system for removing sulfur from a fluid stream containing sulfur and the use thereof in such a transport desulfurization system. The transport desulfurization process utilizes a circulatable particulate material containing alumina, silica, zinc oxide and a metal oxide which is contacted with a fluid stream and thereafter separated and reused with a portion being regenerated.
