2211. MEISENHEIMER, K., AND SCHEUERMANN, A. (Alien Property Custodian). Catalyst for Catalytic Conversion of Carbon Monoxide With Hydrogen. United States Patent 2,363,739, Nov. 28, 1944; appl. filed Feb. 20, 1940, in Germany Feb. 21, 1939. Chem. Abs., vol. 39, 1945, p. 3147.

Catalyst consisting of Co and not >8% of Ag or its compounds is used to catalyze the reaction between CO and H2 carried out at 180°-230° and a pressure of <20 atms. The catalyst may be prepared as follows: A K2CO3 solution is gradually added at room temperature during several hours to an aqueous solution of Co(NO3)2 and AgNO3 to which diatomaceous earth has been added. The precipitate obtained is filtered, washed, and dried at 100° C.
