      407.     ------.  [COMPAGNIE DE BÉTHUNE ]  Hydrocarbons and Alcohols.  British Patent 255,828.  July 27, 1925.  Schmidt, J., Das Kohlenoxyd, Akad.  Verlagsgesell., Leipzig, 1950, p. 173; Chem. Abs., vol. 21, 1927, p. 2978.

Coal-distillation gases, which may be partly dehydrogenated, are passed under high temperature and pressure over a metallic oxide catalyst, for example, over Fe2O3 at 300º-600º under 400 atm. pressure, and then, after cooling and removal of condensed products, are passed over a catalyst having a polymerizing and condensing action at normal or increased pressure, for example, over activated C at 100º-400º.  Alcohols are obtained in the first stage and hydrocarbons in the second.
