Abstract
A method of conducting hydrocarbon synthesis and a highly stable cobalt on alumina catalyst therefor. The inventive method comprises the step of reacting a synthesis gas in a slurry bubble column reactor in the presence of the catalyst. The catalyst comprises a &ggr;-alumina support doped with an amount of lanthana oxide, barium oxide, or a combination thereof effective for increasing the thermal stability of the catalyst in the slurry bubble column reacting system while maintaining or increasing the activity of the catalyst.
