 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.
