3228. SAUTER, E. (Braunkoble Benzin A. G.) [Alkalizing Molded Catalysts.] German Patent 738,368, July 8, 1943; appl. b 196,298, filed Nov. 28, 1941 (Cl. 12 o-1.03) FIAT Reel AA-90, frames 1,496-1,497; PB 70,275; Meyer Transl. PC-S_II, Fischer-Tropsch, vol. 6, chap. 175, 1949, p. 34; Chem Abs., vol. 38, 1944, p. 4106.

Contact catalysts used for synthesizing hydrocarbons from CO and H₂ are treated in their reduced state with solutions of alkalies in an organic solvent. The solvent is anhydrous or H₂O-poor, preferably an alcohol. The saturation of the catalyst with alkalies is carried out in the contact furnace, whereupon the solvent is distilled off.
