3655. STÖWENER, F. (I.G. Farbenindustrie A.G.). [Catalytic Mass.] German Patent 664,817, Sept. 12, 1938 (Cl. 12 g-4.01). Chem. Abs., vol. 33, vol. 33, 1939, p. 332.

A hard, porous adsorptive or catalytic mass is prepared by mixing jellylike or granular precipitates or their dried products, which are virtually free from SiO₂, with just enough liquid to form a paste, drying the paste, and working up as an irreversible colloid or mixing with a peptization agent. Thus, an aqueous solution on Ni₂(SO₄)₃ and MgSO₄ is treated with a soda solution and the precipitated Ni and Mg compound separated, ground, and made into a paste with H₂O. The paste is dried and is used as a contact agent for making CH₄ from CO and H₂. Gives other examples.
