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 a Fischer-Tropsch metal and boron. The Fischer-Tropsch metal preferably includes cobalt and optionally ruthenium or platinum. 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 process for producing hydrocarbons, comprising 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;
A Fischer-Tropsch catalyst comprising a catalytically effective amount of a Fischer-Tropsch metal and boron, wherein the Fischer-Tropsch metal comprises a reduction promoter selected from the group consisting of ruthenium and boron.
A method of preparing a Fischer-Tropsch catalyst comprising dissolving a boron compound, adding a cobalt compound, slurrying a support material into the mixture, and drying the mixture, wherein the boron is added in an amount sufficient to improve at least one of the stability, activity, productivity, or selectivity of the catalyst.
The method of claim 37 wherein the weight ratio of elemental boron to elemental cobalt is from about 0.0005 to 1 to about 0.01 to 1 on a dry basis.
