907. GUYER, J. A. (Phillips Petroleum Co.). Combined Hydrocarbon Conversion-Hydrocarbon Synthesis Process. United States Patent 2,518,775, Aug. 15, 1950; appl. filed Aug. 29, 1947, Serial No. 771,332; 3 claims (Cl. 260-449.6).

Contaminated used catalyst from hydrocarbon conversion is treated with steam and O₃ in a regeneration zone at 1,000º-1,800º F., pressure up to 25 atm. absolute. The regeneration gas has a steam: O₂ ratio in range of 9 : 1-1 : 4 vol. The regeneration effluent gas is suitable synthesis gas for Fischer-Tropsch synthesis. The ratio of CO₂ : CO in volume % is 56 : 44. CO₂ and H₂O are removed. The synthesis gas is contacted with a Fischer-Tropsch catalyst at 340º-700º F. and a pressure 1-20 atm. The effluent is separated into gasoline and heavier oil fractions. The heavier fraction is recycled to the cracking step. 8 United States patents cited.
