  • Cyanide leaching method for recovering platinum group metals from a catalytic converter catalyst
    Patent number: 5160711
    Abstract: A method for recovering platinum group metals from a catalyst material comprises leaching the material with a cyanide solution at a temperature greater than about 100.degree. C. to form soluble platinum group metal-cyanide complexes in solution. Solids are removed from the resulting pregnant leach solution, and the pregnant leach solution is then heated to a temperature sufficient to decompose the platinum group metal-cyanide complexes and precipitate the platinum group metals.
    Type: Grant
    Filed: May 10, 1991
    Date of Patent: November 3, 1992

    Inventors: Gary B. Atkinson, Robert J. Kuczynski, Dennis P. Desmond
  • Thorium oxide-containing catalyst and method of preparing same
    Patent number: 4301032
    Abstract: An alloy of thorium and a Group VIII transition metal is oxidized, for example in air, and subsequently reduced, for example with hydrogen gas, to produce a high surface area catalyst containing thorium oxide and one or more Group VIII transition metals. The catalyst thus produced may be used as such or may be further treated to enhance its activity.
    Type: Grant
    Filed: May 21, 1980
    Date of Patent: November 17, 1981
    Assignee: The United States of America as represented by the Secretary of the Interior
    Inventors: Gary B. Atkinson, Larry J. Nicks, Donald J. Bauer
  • High surface area transition metal catalysts and method of preparing same
    Patent number: 4287095
    Abstract: Highly active catalysts, suitable for use in hydrogenation and other reactions, are prepared from an alloy of one or more of the Group VIII transition metals with a Group IIA metal, a Group IVB metal, or an actinide. The alloy is ground to the desired particle size and is thereafter reacted with a gas, such as carbon monoxide and hydrogen, to form an intimate physical admixture of the Group VIII metal or its corresponding carbide with the oxide of other metal.
    Type: Grant
    Filed: June 24, 1980
    Date of Patent: September 1, 1981

  • Preparation and use of high surface area transition metal catalysts
    Patent number: 4256653
    Abstract: Highly active catalysts, suitable for use in hydrogenation and other reactions, are prepared from an alloy of one or more of the Group VIII transition metals with yttrium or a rare earth metal. The alloy is ground to the desired particle size and is thereafter reacted with a gas containing carbon monoxide and hydrogen to form an intimate physical admixture of the Group VIII metal or its corresponding carbide with the oxide of yttrium or the rare earth metal.
    Type: Grant
    Filed: May 27, 1977
    Date of Patent: March 17, 1981

    Inventor: Gary B. Atkinson
  • Catalyst for synthesis of methanol
    Patent number: 4181630
    Abstract: A catalyst for synthesis of methanol is prepared from an alloy of copper with a metal from the rare earth or actinide series or group IVB of the periodic table. The alloy is reacted with a gas having sufficient oxidizing power to oxidize the rare earth, actinide or group IVB metal.
