CO is hydrogenated to produce oxygenated organic compounds by using a Co (1 part) catalyst promoted with thoria (0.05-0.5 part) supported on bentonite type clay (0.5-3 parts). 75% by weight of the catalyst is smaller than 150 μ and at least 25% is smaller than 40 μ. The catalyst is in a pseudoliquid state. The reaction pressure is 200-300 p. s. i. and the temperature 350°-450° F. The preferred space velocity is 500-800 vol. total feed gas per hr. per vol. catalyst. The CO2 concentration of gaseous feed mixture is <2%. The liquid hydrocarbon fraction containing the oxygenated organic compounds C6-C7 alcohols is recycled to the reaction zone to increase the yield. A yield of oil 97-126 cc. And a yield of H2O 99-171 cc. Per m3 fresh feed gas have been obtained. 1 literature ref. And 7 United States patents cited. |
