A process for the conversion of synthesis gas to a product containing liquid hydrocarbons with an, activated, supported catalyst prepared by the steps, in sequence, of (A) impregnating an alumina or silica support with a cobalt carbonyl, (B) subjecting said cobalt carbonyl-impregnated alumina or silica support to an activation procedure comprising the steps of, in sequence, (i) reduction in hydrogen, (ii) oxidation with an oxygen-containing gas, and (iii) reduction in hydrogen, said activation procedure being conducted at a temperature below about 450°C., to produce an, activated catalyst having an activity after said step (iii) that is greater than the activity of the catalyst after said step (i), and contacting a synthesis gas comprising hydrogen and carbon monoxide under synthesis conversion conditions with said, activated catalyst to form a product containing liquid hydrocarbons.
