A catalyst useful for the production of hydrocarbons from synthesis gas, in the Fischer-Tropsch reaction, is disclosed. The catalyst includes cobalt and rhenium and may be supported on an alumina support. The catalyst further includes a promoter selected from among boron, manganese, vanandium, phosphorous, and the alkali metals. The promoter preferably improves the activity for the production of hydrocarbons by at least about 5%. The improved activity may be an increased productivity, increased CO conversion, and the like. The hydrocarbons may have a weight range useful for making diesel fuel, (e.g. C11+ hydrocarbons). Alternately, the hydrocarbons may have a weight range useful for making gasoline (e.g. C5+ hydrocarbons). The catalyst may be made by co-dispersing the promoter with the cobalt or by layering the promoter over the cobalt.
