  • Process for purifying a titanium-bearing material and upgrading ilmenite to synthetic rutile with sulfur trioxide
    Patent number: 4120694
    Abstract: A process for removing impurities from an oxide of titanium-bearing material such as a titania slag by treating the material with SO.sub.3 gas and subsequently leaching with a liquid. In particular a process for upgrading an ilmenite ore by preparing a titania slag therefrom and purifying the slag such that it may be used as a synthetic rutile suitable for use in a fluidized-bed chlorination reactor to produce titanium tetrachloride which can be reoxidized to TiO.sub.2.
    Type: Grant
    Filed: September 6, 1977
    Date of Patent: October 17, 1978
    Assignee: The United States of America as represented by the Secretary of the Interior
    Inventors: Gerald W. Elger, Ruth A. Stadler, Philip E. Sanker
  • 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

    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.
