2569. PAGE, R., AND THOMAS, E. B. (Celanese Corp. of America). Catalyst for Methane Production From Carbon Monoxide and Hydrogen. United States Patent 2,151,329, Mar. 21, 1939; appl. filed Oct. 20, 1936 (Cl. 23-237). Chem. Abs., vol. 33, 1939, p. 5002.

Catalyst is prepared by precipitating Ni and Al hydroxides from a solution of their nitrates containing 4 times as much Ni nitrate as Al nitrate, the washed precipitate is formed into a shaped mass and dried, all these operations being conducted at a temperature < 30, and the Ni hydroxide is subsequently reduced at a temperature of about 250. Example: A mixture of CO and coal gas is treated for removal of S. The resulting gas consisting mainly of CO, H2, and CH4 in proportion of 1:2:1, still containing about 45 mg. S per 1. is passed over the catalyst at about 350. The resulting gas contains over 50% CH4.
