2057. ------. [LINCKH, E., AND WINKLER, F.] (I. G. Farbenindustrie A. G.). [Reactions Between Carbon Oxides and Hydrogen to Yield Hydrocarbons or Oxygen-Containing Compounds.] German Patent 721,359, June 2, 1942; appl. I 52,079, filed Apr. 10, 1935 (Cl. 12 o-1.03). FIAT Reel AA-90, frames 1,622-1,624; PB 70,275; Meyer Transl. PC-S-II, Fischer-Tropsch, vol. 5, chap. 160, 1949, p. 46; Chem. Abs., vol. 37, 1943, p. 4883.

Hydrogenation of CO is highly exothermic and the methods in use for controlling the temperature of the reaction are considered inefficient. It is suggested that a cooling coil of steel or Fe be employed to supply simultaneously the necessary catalytic action and cool the reactants. Suitable activating agents, for example, U-, Cu-, Ag-, or alkali compounds, are applied to the cooling coil by means of etching with acids containing these materials, plating, or other methods.
