2713. ------. [POTTS, H. E.] Synthesis of Hydrocarbons From Mixtures of Carbon Monoxide and Hydrogen. British Patent 526,814, Sept. 26, 1940; appl. filed Mar. 11, 1939. Chem. Abs., vol. 35, 1941, p. 7155.

Synthesis gas consisting of a mixture of CO and H₂, if desired together with other gases, is passed at 1,000°-1,250° over bauxite in such a way that the gas remains 0.5 sec. in the hot zone. The gas is then freed from H₂S by means of an Fe oxide purification mass and after cooling passed over a Co-Th oxide catalyst at ordinary pressure and at about 180°. The yield of liquid hydrocarbons produced amounts to 115 cc. per m.³ of CO-H₂ mixture. Quartz can be used instead of bauxite.
