3405.  SOCIÉTÉ D’ÉTUDES SCIENTIFIQUES ET D’ENTREPRISES INDUSTRIELLES.  [Hydrocarbons]  French Patent 692,395, June 12, 1929.  Chem. Abs., vol. 25, 1931, p. 1259.

Unsaturated hydrocarbons, particularly C2H2 and gaseous mixtures for the synthesis of oxygenated organic products and NH3 are made by separating coke-oven gas into its constituents by liquefaction. mixing theH2 or gas rich in H2 thus obtained by separation of air into its constituents, using the O2 from this air for the regulated combustion of air or a part of the CH4or gas rich in CH4 from the coke oven gas  separating the unsaturated hydrocarbons from the combustion, and joining the residual gases of this separation composed of H2 CO and some N2 with the H2 from the coke oven gas to form a mixture suitable for the synthesis of compounds such as MeOH and NH2.
