Abstract
Abstract A catalyst useful in the conversion of synthesis gas to diesel fuel in a fluidized bed is prepared by contacting finely divided alumina with an aqueous impregnation solution of a cobalt salt, drying the impregnated support and thereafter contacting the support with a nonaqueous, organic impregnation solution of salts of ruthenium and a Group IIIB or IVB metal.
