2570. PAGE, R., THOMAS, E. B., AND BRITISH CELANESE, LTD. Catalyst for the Production of Methane From Carbon Monoxide and Hydrogen. British Patent 465,157, Apr. 29, 1937. Chem. Abs., vol. 31, 1937, p. 7883.

Catalyst is made by co-precipitating in the cold Ni oxide and Al₂O₃, shaping the precipitate, and reducing the Ni oxide. The Al₂O₃ may be partly or wholly replaced by another dehydrating or dehydrogenating oxide, for example, ThO₂, blue oxide of W, TiO₂, MgO. The catalyst may be prepared as described in British Patent 354,351. The CH₄ reaction is preferably effected at 330°-400° and at atm. or slightly increased pressure.
