Abstract
A particulate catalyst comprises an intimate mixture of cobalt and aluminum compounds at an atomic ratio in the range 10:1 to 2:1 (Co:Al), which when reduced at 425° C., has a cobalt surface area as measured by hydrogen chemisorption at 150° C. of at least 30 m2/g of catalyst. The catalyst is prepared by sequential precipitation of cobalt with aluminum ions in the presence of an alkaline precipitation agent. The catalyst may be used for the hydrogenation of unsaturated compounds or the Fischer-Tropsch synthesis of hydrocarbons.
