3362.   ------.  [SMITH, W. M.]  (Standard Oil Development Co.).  Hydrogenation Process.  United States Patent 2,574,355, Nov. 6, 1951; appl. filed Aug. 13, 1948, Serial No. 44,219; 3 claims (Cl. 260-450).

Oxygenated compounds contained in a hydrocarbon synthesis product formed by the hydrogenation of an oxide of C are reduced, without substantial hydrogenation of olefins and aromatics contained therein, by treating the synthesis product with H₂ at elevated temperatures and pressures (700° F. and 100 p.s.i.) in the presence of a catalyst consisting essentially of 1 of the class consisting of Co and Ni chemically combined with a metal oxide of group VI on active Al₂O₃.  A suitable catalyst comprises a mixture of Co molybdate (CoMoO₄) and Mo trioxide on Al₂O₃.  Gives directions for preparing the catalyst.  The object of the process is to improve the quality of the synthetic oil and thereby the gasoline made therefrom.
