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 destablizing 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.
L'invention concerne un procédé pour produire des hydrocarbures en mettant en contact un courant d'alimentation contenant de l'hydrogène et du monoxyde de carbone avec un catalyseur dans une zone de réaction maintenue dans des conditions favorisant la conversion et efficaces pour produire un courant effluent contenant des hydrocarbures. L'invention est caractérisée en ce que l'on utilise un catalyseur préparé par un procédé qui consiste, premièrement, à former un gel catalytique par la déstabilisation d'un colloïde aqueux comprenant (a) au moins un métal catalytique qui convient aux réactions Fischer-Tropsch (p.ex., le fer, le cobalt, le nickel et/ou le ruthénium), (b) oxyde de cérium, oxyde de zircone, oxyde de titane et/ou oxyde d'aluminium colloïdal, plus éventuellement (c) Al(OR)¿3?, Si(OR)¿4?, Ti(OR)¿4? et/ou Zr(OR)¿4?, chaque R représentant un groupe alkyle possédant de 1 à 6 atomes de carbone; et, deuxièmement, à sécher le gel.
