  • Hydrogenation catalysts
    Patent number: 6462244
    Abstract: A hydrogenation catalyst which is sulfur tolerant and which includes from about 0.1 to about 1 percent platinum by weight and from 0.2 to about 2 percent by weight palladium on a predominantly theta alumina carrier. Also disclosed is a process for the manufacture and use of the hydrogenation catalyst.
    Type: Grant
    Filed: October 2, 2001
    Date of Patent: October 8, 2002

  • Nickel hydrogenation catalyst
    Patent number: 5258346
    Abstract: An extruded nickel oxide on refractory oxide hydrogenation catalyst, having, in its reduced state, a nickel surface area greater than 30 m.sup.2 /gm of reduced nickel in the catalyst and 15 to about 65 volume percent of pores having diameters of about 300 to about 1000 angstroms, is highly active for the hydrogenation of aromatics in heavy hydrocarbon streams and is relatively resistant to sulfur poisoning.

    Date of Patent: November 2, 1993
    Assignee: United Catalysts Inc.
    Inventors: Dinah C. Huang, Edward K. Dienes, Jon P. Wagner
  • High temperature shift catalyst and process for its manufacture
    Patent number: 4861745
    Abstract: An improved catalyst for the high temperature shift reaction especially suited for low steam to gas ratio applications is made by dipping an iron oxide-chromium oxide catalyst in an aqueous copper salt solution, drying the catalyst and calcining it.
    Type: Grant
    Filed: August 3, 1988
    Date of Patent: August 29, 1989
    Assignee: United Catalyst Inc.
    Inventors: Dinah C. Huang, Jeffrey L. Braden
  • Methanol synthesis catalyst and method for its preparation
    Patent number: 4376721
    Abstract: A method is provided to promote, stabilize and strengthen metal catalysts used in the fluidized bed process for methanol synthesis which comprises the dipping of such catalysts into an alcoholic solution of metal alkoxide salt. The resulting improved catalyst is characterized by high density, low loss on attrition, and improved stability and catalytic activity.
