2840. Rubin, L. C., Riblett, E. W., and McGrath, H. G. (M. W. Kellogg Co.). Liquid Hydrocarbons, United States Patent 2,615,025, Oct. 21, 1952. Chem. Abs., vol. 47, 1953, p. 2966.

Liquid hydrocarbons are formed at least in 50% yield by passing H₂ and CO in molar ratios of 205 : 1 upward in a reaction zone through a Co-containing catalyst in suspension at 440º-500º F. and at 45 p.s.i.g. pressure or less. The product is suitable for diesel fuel. In an example, gas containing CO 30.9%, H₂ 61.4%, and inerts 7.7% is introduced at a rate of about 40 cu. ft. per hr. per lb. of Co catalyst at an average temperature of 440º F. Of the CO charged, 47.5% was converted to liquid hydrocarbons containing >3 C atoms per molecule and end b.p. 670º F.; 11% was converted to liquid hydrocarbons containing 1-2 C atoms per molecule: and 6% to CO₂. Liquid product was 131 cc. per m.³ gas charged.
