113. ------. [BADISCHE ANILIN- UND SODA-FABRIK] [Production of Methane From Water Gas.] German Patent 396,115. June 3, 1924; appl. filed Mar. 24, 1923. Chem. Zentralb., 1924, II, p. 1269.

CH₄ is produced from water gas or the like by the catalytic conversion at 700°-800° of the CO by means of steam and by subsequent passing of the resulting gas mixture over catalysts such as Ni. The difficulty removable S in the initial gas mixture is completely or partly converted into H₂S and is then easily removed.
