      189.            BLACK, J. F.  (Standard Oil Development Co.).  Hydrocarbons From Carbon Monoxide and Hydrogen.  United States Patent 2,435,551, Feb. 3, 1948.  Chem. Abs., vol. 42, 1948, p. 2419.

CO and H₂ are reacted at 300°-450° F. in the presence of a fluidized catalyst comprising Ni chromite prepared by combining at elevated temperature and under agitation an aqueous solution of a Ni salt with an ammoniacal solution of NH₄ chromate and separating, drying, and calcining the precipitate formed.  The use of the novel catalyst makes unnecessary the otherwise required accurate temperature control of the Fischer-Tropsch process.
