Abstract
A process is disclosed for producing hydrocarbons. The process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons. In accordance with this invention, the catalyst used in the process includes at least cobalt, rhenium, and a promoter selected from the group including boron, phosphorus, potassium, manganese, and vanadium. The catalyst may also comprise a support material selected from the group including silica, titania, titania/alumina, zirconia, alumina, aluminum fluoride, and fluorided aluminas.

A Fischer-Tropsch catalyst comprising cobalt, rhenium, a promoter comprising at least one element selected from the group consisting of boron and phosphorus and a support material selected from the group consisting of aluminum fluoride and fluorided aluminas.
A method of preparing a Fischer-Tropsch catalyst comprising dissolving a rhenium compound and a promoter containing compound, adding a cobalt compound, slurrying a support material into the mixture, and drying the mixture, wherein the support is selected from the group consisting of aluminum fluoride and fluorided aluminas.
A method of preparing a Fischcr-Tropsch catalyst comprising dissolving a rhenium compound and a promoter containing compound, adding a cobalt compound, slurrying a support material into the mixture, drying the mixture, and reducing the dried mixture in the presence of a hydrogen containing gas, wherein the promoter is selected from the group consisting of boron, phosphorus, potassium, manganese, and vanadium and wherein the support material is selected from the group consisting of fluorided alumina and aluminum fluoride.
