Processes and catalysts for conducting Fischer-Tropsch synthesis in a slurry bubble column reactor (SBCR). One aspect of the invention involves the use of cobalt catalysts without noble metal promotion in an SBCR. Another aspect involves using palladium promoted cobalt catalysts in an SBCR. Methods for preparing noble metal promoted catalysts via totally aqueous impregnation and procedures for producing attrition resistant catalysts are also provided.

[ What is claimed is:] [1.] A process for preparing a supported, ruthenium-promoted, cobalt catalyst comprising the steps of:(a) calcining a support having a porous structure;(b) co-impregnating said support with an amount of an aqueous solution consisting essentially of water, cobalt nitrate, and at least one water soluble promoter compound, wherein said one water soluble promoter compound is a water soluble ruthenium compound, to obtain a catalyst precursor, said amount of said aqueous solution being not substantially more than an amount effective to achieve incipient wetness with a desired loading of cobalt and ruthenium and to obtain a uniform distribution of both said cobalt and said ruthenium within said porous structure,(c) drying said catalyst precursor to obtain a dried catalyst precursor;(d) calcining said dried catalyst precursor by slowly raising its temperature over time to obtain a calcined catalyst precursor; and(e) reducing said calcined catalyst precursor in a suitable reducing gas to obtain a final catalyst composition, rein said process is a totally aqueous impregnation process and said water soluble ruthenium compound is of a type sufficiently soluble in water in the presence of said cobalt nitrate to make said ruthenium compound effective for totally aqueous, incipient wetness impregnation.
