701. ------. [FISCHER, F., AND TROPSCH, H.] [Hydrocarbons.] German Patent 567,069, De. 27, 1932; appl. F 62,091, filed Sept. 15, 1926 (Cl. 12 o-1). FIAT Reel AA-88, frames 4,001-4,002; PB 70,273; Chem. Abs., vol. 27, 1933, p. 1499.

Hydrocarbons are treated in known manner with steam and/or CO₂, to produce a gas mixture of the water-gas type, and this mixture is led over a catalyst at atmospheric pressure to produce other hydrocarbons. Gives an example in which natural CH₄ is led with CO₂ over spongy Fe at 950º, and the resulting gas is led at 270º and atmospheric pressure over a mixture of Co and ZnO, giving liquid hydrocarbons of the benzine type. The residual gases are returned to the process.
