 1885.    ---------------.  [MURATA, Y., MAKINO, S., AND TSUNEOKA, S.]  Synthesis of Benzine From Carbon Monoxide and Hydrogen at Ordinary Pressure.  XLIX.  Influence of Various Metals, Metal Oxides and Precipitants on Fe-Cu-Kieselguhr Catalysts.  Jour. Soc. Chem. Ind. (Japan), vol. 42, suppl., 1939, pp. 107-112; Sci. Papers Inst. Phys. Chem. Research (Tokyo), vol. 35, 1939, pp. 356-364; Chem. Abs., vol. 33, 1939, p. 4762.

        Addition of U₃O₈, ThO₂, Al₂O₃ and Cr₂O₃ to Fe-Cu-kieselguhr catalysts brings about very poor gasoline yields, especially with the last 2 oxides.  The addition of 2% Mn or MgO to a catalyst consisting of Fe+25% Cu+125% kieselguhr+2% K₂CO₃ produces a yield of 88 cc. per m.³  The presence of Ni accelerates the reaction provided the CO:H₂ is 1:2.  Co is less harmful than Ni.  H₂O formation is noticed if the catalyst contains more than 2.5% Ni.  Gasolines produced with Ni catalysts also have a low I number.  Addition of ThO₂, U₃O₈, etc., to an Fe catalyst containing 10% Ni proved ineffectual.  Na₂CO₃ is the most suitable precipitant for producing the catalyst.  Replacing the carbonate with caustic soda proved damaging.
