A process is disclosed for producing hydrocarbons by 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. The process is characterized by using a catalyst prepared by a method involving (1) forming a catalyst gel by destabilizing an aqueous colloid comprising (a) at least one catalytic metal for Fischer-Tropsch reactions (e.g., iron, cobalt, nickel and/or ruthenium), (b) colloidal cerium oxide, zirconium oxide, titanium oxide and/or aluminum oxide, and optionally (c) Al(OR)3, Si(OR)4, Ti(OR)4 and/or Zr(OR)4 where each R is an alkyl group having from 1 to 6 carbon atoms; and (2) drying the gel.
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, wherein the catalyst comprises a catalytically active metal selected from the group consisting of iron, cobalt, nickel, ruthenium, and combinations thereof dispersed in a matrix material comprising a derivative of a destabilized aquasol comprising a colloidal oxide of a matrix metal selected from the group consisting of cerium, zirconium, titanium, aluminum, silicon, and combinations thereof.
