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 is prepared by a method including at least (1) forming a catalyst gel by mixing (a) at least one dissolved compound of a catalytic metal for Fischer-Tropsch reactions (e.g., iron, cobalt, nickel and/or ruthenium compound(s) dissolved in water and/or ethanol); (b) (i) at least one dissolved alkoxide of titanium, zirconium and/or tantalum, and optionally (ii) at least one dissolved aluminum compound (the alkoxide and aluminum components (i) and (ii) being dissolved in a non-aqueous solvent; and at least when necessary to hydrolyze the alkoxide component (i) and aluminum compound component (ii), (c) water supplement; and (2) drying the gel. |
