1875. TSUNEOKA, S., AND MURATA, Y. Benzine Synthesis From Carbon Monoxide and Hydrogen at Ordinary Pressure. XXXIX. Properties of a Precipitated Nickel-Cobalt Catalyst. Jour. Soc. Chem. Ind. (Japan), vol. 41, suppl., 1938, pp. 52-57; Sci. Papers Inst. Phys. Chem. Research (Tokyo), vol. 34, 1938, pp. 280-294; Chem. Abs., vol. 32, 1938, p. 3945.

Precipitated Ni-Co catalyst (I), without the addition of an accelerator, is useless for the production of benzine. with ThO₂ (II), Al₂O₃ or Cr₂O₃ as accelerators the optimum temperature of reaction is comparable to that of U₃O₈ (III). (II) and (III) are excellent accelerators while Mn is not very effective. With (I) the optimum amount of Mn is 15-20%. the optimum reduction temperature of a Ni-Co-Mn catalyst is at 350°, while if (II) or (III) is added, the reduction is more successful at 400°. The most suitable mixing proportions of Co and Ni are 1:1.
