 1488.    HOOVER, C. R., DORCAS, M. J., LANGLEY, W. D., AND MICKELSON, H. G.  Catalytic Preparation of Unsaturated Hydrocarbons From Carbon Monoxide and Hydrogen.  Jour. Am. Chem. Soc., vol. 49, 1927, pp. 796-805; Chem. Abs., vol. 21, 1927, p. 1444.

       Mixture of approximate equal parts of CO and H2 with a trace of O2, when passed at a space velocity of 1,500-2,000 over a Ni-Pd catalyst supported on Al or pumice stone, produced 1-3% of C2H4 at temperatures in the neighborhood of 100°; the catalyst lost 0.5% of its efficiency in 30 hr.  Other catalysts in order of decreasing activity were Ni-Cu-Pd, Fe-Ni-Pd, Ni-Pt, Cu-Co-Fe, Cu-Pd, Cu-Co-Ni, C-Pd, Ni-Cu, Cu-Co.  While saturated hydrocarbons were not specially sought, Ni and Ni-Pd catalysts yielded from 20-25% CH4 at temperatures in the neighborhood of 250°.  The catalysts showed little decrease in activity after several days’ use.
