982. ------. [HEMMINGER, C. E.] (Standard Oil Development Co.). Processing of Hydrocarbon Synthesis Products. United States Patent 2,516,699, July 25, 1950; appl. filed Jan. 15, 1947, Serial No. 722,275; 1 claim (Cl. 260-450). Chem. Abs., vol. 45, 1951, p. 848.

Gasoline heart cut, C₆ to 350º F. cut, from Fischer-Tropsch synthesis, is subjected to a severe catalytic treatment, the heavy naphtha gas oil cut, 350º F. and above, is subjected to a milder catalytic treatment, and the C₂-C₃ olefins are polymerized. Bauxite to a silica-alumina (10-25 wt. % alumina) may be used. A solid phosphoric acid catalyst is used for treating the lighter fractions. Any continuous treating unit may be used, but a fluid reactor and regenerator system is preferred. Oil product is nondestructively hydrogenated and superior diesel and heating oil are recovered. 1 literature ref., 2 foreign patents, and 9 United States patents cited.
