  • Self-disintegrating Raney metal alloys
    Patent number: 4175954
    Abstract: A method of preparing a Raney metal alloy which is capable of self-disintegrating when contacted with water vapor. The self-disintegrating property is imparted to the alloy by incorporating into the alloy from 0.4 to 0.8 weight percent carbon. The alloy is useful in forming powder which can be converted to a Raney metal catalyst with increased surface area and catalytic activity.
    Type: Grant
    Filed: July 24, 1978
    Date of Patent: November 27, 1979
    Assignee: The United States of America as represented by the United States Department of Energy
    Inventors: Laurance L. Oden, James H. Russell
  • Method for producing supported Raney nickel catalyst
    Patent number: 4049580
    Abstract: A method for making a supported Raney nickel catalyst by coating a nickel substrate with aluminum or aluminum-nickel alloy, heat treating the coated substrate above the melting point of aluminum but below 1133.degree. C, quenching at a temperature below 854.degree. C to form NiAl.sub.3 as a solid phase in the substrate. The Raney nickel alloy coating is activated in the usual manner by leaching with sodium hydroxide solution.
    Type: Grant
    Filed: July 23, 1976
    Date of Patent: September 20, 1977
    Assignee: The United States of America as represented by the Secretary of the Interior
    Inventors: Laurance L. Oden, Philip E. Sanker, James H. Russell
  • Production of supported Raney nickel catalysts by reactive diffusion
    Patent number: 4043946
    Abstract: A method for making a supported Raney nickel catalyst by casting molten aluminum heated to about 850.degree. C around a nickel substrate in a mold heated to about 1,050.degree. C, retaining the metals in the mold at 1,050.degree. C for about 30 seconds, allowing the mold to cool to ambient temperature, removing the casting from the mold and activating it by leaching with hot sodium hydroxide.
