  • Shaped heterogeneous catalysts
    Patent number: 8557729
    Abstract: A catalyst unit is described in the form of a cylinder having a length C and diameter D, which has two or more flutes running along its length, wherein said cylinder has domed ends of lengths A and B, such that (A+B+C)/D is in the range 0.50 to 2.00, and (A+B)/C is in the range 0.40 to 5.00. The catalyst may be used particularly in reactions where hydrogen is a reactant such as hydroprocessing, hydrogenation, water-gas shift reactions, methanation, hydrocarbon synthesis by the Fischer-Tropsch reaction, methanol synthesis and ammonia synthesis.
    Type: Grant
    Filed: August 24, 2009
    Date of Patent: October 15, 2013
    Assignee: Johnson Matthey PLC
    Inventors: Daniel Lee Cairns, Mileta Babovic, Terence James Fitzpatrick, Elizabeth Margaret Holt, Colin William Park, William Maurice Sengelow, Edmund Hugh Stitt
  • Process for preparing catalyst supports having reduced levels of contaminants
    Patent number: 8003566
    Abstract: A method of preparing a catalyst support is described comprising washing a precipitated metal oxide material with water and/or an aqueous solution of acid and/or base such that contaminant levels in said precipitated metal oxide are reduced. The method may be applied to precipitated alumina materials to reduce contaminants selected from sulphur, chlorine, Group 1 A and Group 2A metals. The catalyst supports may be used to prepare catalysts for the Fischer-Tropsch synthesis of hydrocarbons.
    Type: Grant
