Abstract
A hydrogen regenerable hydrocarbon synthesis catalyst useful for preparing higher hydrocarbons from synthesis gas is prepared by depositing cobalt and ruthenium on a refractory carrier and oxidizing and reducing the catalytic metals to form a catalyst in which the cobalt and ruthenium are in intimate contact.
Claims10
A hydrocarbon synthesis catalyst prepared by a process comprising impregnating a refractory support comprising titania with solutions of catalytically active amounts of cobalt and ruthenium salts, drying the impregnated support, reducing the cobalt and ruthenium, treating the reduced metals with an oxygen containing stream at conditions sufficient to form oxides of cobalt and oxides of ruthenium and reducing the cobalt and ruthenium oxides.
