 1845.    KODAMA, S. AND FUJIMURA, K.  Catalytic Reduction of Carbon Monoxide Under Ordinary Pressure.  VII.  Effect of Alkalies on Iron-Copper Catalysts.  Jour. Soc. Chem. Ind. (Japan), vol. 34, suppl., 1931, pp. 14-16; Sci. Papers Inst. Phys. Chem. Research (Tokyo), vol. 29, 1936, pp. 272-279; Chem. Abs., vol. 25, 1931, p. 1952; vol. 30, 1936. p. 8570.

        With a Cu-Fe catalyst prepared from the nitrates, 3.0 cm.³ of oil containing a small quantity of a substance like vaseline was obtained at 270° from 141 l. of water gas.  Addition of 0.0005-0.05 mol. of Na₂CO₃ to the above catalyst increased its initial activity and favored formation of higher hydrocarbons.  With catalysts containing alkalies there is a high gas contraction at first, the activity diminishing gradually.  The catalyst may become coated with the higher hydrocarbon.  No dimunition of activity occurs with alkali-free catalysts.  The best catalyst contains Fe 1 atom, Cu 1 atom, Na₂CO₃ 0.005 mol.
