 1884.    MURATA, Y., MAKINO, S., AND TSUNEOKA, S.  Synthesis of Benzine From Carbon Monoxide and Hydrogen at Ordinary Pressure.  XLVIII.  Influence of Addition of Copper and Alkali on New Iron Catalysts.  Jour. Soc. Chem. Ind. (Japan), vol. 42, suppl., 1939, pp. 107-112; Sci. Papers Inst. Phys. Chem. Research (Tokyo), vol. 35, 1939, pp. 348-355; Chem. Abs., vol. 33, 1939, p. 4761.

        Experiments carried out with a catalyst containing Fe+125% kieselguhr +3% K₂CO₃ (% based on weight of Fe) to which various amounts of Cu were added show that best gasoline yields were obtained by addition of Cu in amounts of 20-40% of the weight of Fe.  The addition of 2-3% of alkali carbonate (K₂CO₃) to catalysts of composition Fe+25% Cu+125% kieselguhr, and Fe+5% Ni+25% Cu+125% kieselguhr increases the yield for CO:H₂ ratios both of 1:1 and 1:2.  In general, however, the larger the CO content of the gases the smaller should be the addition of alkali.  Degree of unsaturation increases with increasing amounts of alkali.
