 1860.    ---------------.  [TSUNEOKA, S., AND MURATA, Y.]  Benzine Synthesis From Carbon Monoxide and Hydrogen at Ordinary Pressure.  XXIV.  The Influence of the Particle Size and the Hydrogen Treatment or Oxidation Conditions of the Alloy Catalysts.  Jour. Soc. Chem. Ind. (Japan), vol. 38, suppl., 1935, pp. 206-212; Sci. Papers Inst. Phys. Chem. Research (Tokyo), vol. 27, 1935, pp. 23-31; Chem. Abs., vol. 29, 1935, p. 4551.

        Activity of the catalyst became less with a decrease in particle size.  The H₂ pretreatment of the Ni-Co-Si alloy catalyst is unimportant, almost no increase in activity being obtained by H₂ pretreatment at 220°.  A H₂ treatment at 350°-450° is detrimental and at 450° it results in complete inactivation of the catalyst.  Oxidation of the catalyst before and after H₂ treatment is likewise considered unfavorable.
