3460. ----- [STANDARD OIL CO.]  Catalyst for Fischer-Tropsch Synthesis.  British Patent 641,266, Aug. 9, 1950.  Chem. Abs., vol. 44, 1950, p. 11,067.

Hydrocarbon synthesis catalyst is prepared by mixing 5% K₄Sb₂O₇ with 95% Fe₃O₄ as follows:  The mixture is slurried in EtOH, dried, ground, and calcined in air at 1,000° F. for 4.5 hr.  The catalyst is reduced before use.  High yields of hydrocarbons and oxygenated compounds are found when equimolar H₂+CO synthesis gas is passed over this catalyst at 550° F. and 150 p. s. i.  with space velocity of 200 vol. per vol. catalyst per hr.
