PROMOTED CATALYSTS AND FISCHER-TROPSCH PROCESSES

摘要

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 a promoter selected from the group consisting of molybdenum, tin, gallium, and zinc. The Fischer-Tropsch metal preferably includes cobalt. The catalyst may also include a support material selected from the group including silica, titania, titania/alumina, zirconia, alumina, silica-alumina, aluminum fluoride, and fluorided aluminas.
