3305.  SCHULZ, E. H., AND EISENSTECKEN, F.  (Vereinigte Stahlwerke A. G.)  Catalytic Production of Hydrogen.  British Patent 314,870, July 3, 1928.  Chem. Abs., vol. 24, 1930, p. 1475.

Gas mixture rich in H₂ is obtained by passing distillation gases, hydrocarbons, or gaseous mixtures containing hydrocarbons over catalysts, such as Fe, Co, Ni, Cr, Al, Mn, Si, C, Cu, V, W, and compounds or mixed crystals of these elements, in admixture with superheated steam at temperatures of 1,000° or higher.  An example is given of the passage of coke-oven gas, together with superheated steam, at 1,100° over a catalyst comprising Cr and Al to obtain a product composed almost entirely of H₂, N₂, and CO.  a passage of carborundum may be used for the reaction. and when so used it also has the effect of a catalyst.  Gases thus produced are suitable for use in NH₃ or MeOH synthesis or in reducing metal oxides.
