3265.  SCHILLER, G., AND WIETZEL, G. (I. G. Farbenindustrie A. G.).  Hydrogen from Hydrocarbons.  united States Patent 2,056,911, Oct. 6, 1936; appl. filed Jan. 11, 1932.  Chem. Abs., vol. 30, 1936, p. 8541.

Gas comprising a vaporized hydrocarbon, such as a mixture of CH₄ with higher hydrocarbons, is brought into contact at a temperature of 400°-1000° and in the presence of steam, successively with 2 layers of different catalysts, the 1^st of which contains a metal of the Fe group, such as Ni, distributed in a set hydraulic binding agent, and the 2d  of which has a higher catalytic activity than the 1^st and contains an Fe-group metal with an activating addition of a nonreducible oxide of a metal from groups 2-6 of the periodic system, such as oxides of Al and Mg. and is at a higher temperature than that of the 1^st catalyst.
