Abstract: A process for converting synthesis gas composed of hydrogen and carbon monoxide to hydrocarbons. The process includes the step of contacting at reaction conditions a synthesis gas feed to a catalyst which includes cobalt in catalytically active amounts up to about 60 wt % of the catalyst and rhenium in catalytically active amounts of about 0.5 to 50 wt % of the cobalt content of the catalyst supported on alumina. A metal oxide promoter may be added.
