3129.----- [RUHRCHEMIE, A. G.]  [Process for Producing Methane From Mixtures of Oxides of Carbon With Hydrogen.]  german Patent Appl. R 112,110-, R 604, filed Feb. 4, 1942 (Cl. IV d-12 o).  FIAT Reel K-30, frames 7,715-7,716; Meyer Transl. PC-S-II, Fischer-Tropsch, vol. 2, chap. 82, 1948, p.18.

In producting CH4 from mixtures of oxides of C with H2, catalysts of Ni are used containing 5-50 parts MgO to 100 parts of Ni deposited on carrier substances, such as kieselguhr, in amounts preferably of about 50 parts to 100 of Ni.  The gases are passed over the catalyst at a rate of about 25-100 l. per 4 gm. Ni per hr.
