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 .gamma.-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.

[ What is claimed is:] [1.]1. A method of Fischer-Tropsch hydrocarbon synthesis comprising the step of reacting a synthesis gas in a Fischer-Tropsch reaction system in the presence of a catalyst comprising:a .gamma.-alumina support having an internal structure comprising .gamma.-alumina and a controlled amount of a dopant selected from the group consisting of a lanthanum dopant, a barium dopant, and combinations thereof andan amount of cobalt, on said .gamma.-alumina support, effective for said Fischer-Tropsch hydrocarbon synthesis in said Fischer-Tropsch reaction system,wherein said controlled amount of said dopant is an amount effective for increasing the thermal stability of said catalyst for use in said Fischer-Tropsch reaction system without reducing the activity of said catalyst for said Fischer-Tropsch hydrocarbon synthesis.
