3747.  THOMAS, C.L. (Universal Oil Products Co.).  Hydrogenation-Isomerization Catalyst.  United States Patent 2,406,864, Sept. 3, 1946; appl. filed May 31, 1939, Serial No. 276,553; 14 claims (Cl. 260-449.6).  Chem. Abs., vol. 40, 1946, p. 7574.

In the synthesis of hydrocarbons of gasoline and higher boiling range from CO and H₂, a motor fuel with improved octane qualities may be produced directly by using catalyst that has in addition to the hydrogenation component a second catalytic component known to function as an isomerizating and cracking agent.  In the preferred method the hydrogenation component is prepared by precipitating the hydroxides of the metals on kieselguhr.  The isomerization cracking component is prepared in powdered form in a separate operation and the two components are mixed and shaped into pellets.  The catalyst contains thoria and at least one of the metals of group VIII associated with a major proportion of silica and a minor proportion of at least one of the compounds, alumina and zirconia.
