182. ------. [BEWLEY, T., AND BRAMWYCHE, P. L.] (Distillers Co., Ltd.). Preparation of Hydrogenation Catalysts by Reduction. United States Patent 2,623,078, Dec. 23, 1952: appl. filed Aug. 8, 1950, Serial No. 178,360, in Great Britain Aug. 19, 1949: 15 claims (Cl. 260-690).

Active hydrogenation catalysts are prepared by treating a kieselguhr-supported Cu or Ni compound, which is reducible to the metal with H₂ while the compound is suspended in a liquid medium such as organic polysiloxane. The reduction may be a preliminary step or the material to be hydrogenated may be present. 2 United States patents cited.
