In a second embodiment, the Fischer-Tropsch catalyst is a cobalt-based catalyst with a first precious metal promoter and a second metal promoter on an aluminum oxide support, the catalyst having from about 5 wt % to about 60 wt % cobalt; from about 0.0001 wt % to about 1 wt % of the first promoter, and from about 0.01 wt % to about 5 wt % of the second promoter. The high surface area transition metal-based catalysts of the present invention are prepared in a non-acidic solution at a pH greater than about 7.0 , and starting with a non-acidic transition metal complex. The resulting product is a catalyst with a uniform distribution of metal throughout the catalyst particles, with a smooth and homogeneous surface morphology, and with slow crystallite growth upon heating.

Catalysts

A process for preparing a catalyst precursor includes forming a slurry of particles of an insoluble metal compound, where the metal of the insoluble metal compound is an active catalyst component, with particles and/or one or more bodies of a pre-shaped catalyst support in a carrier liquid. The particles of the insoluble metal compound are thus contacted with the particles and/or the one or more bodies of the pre-shaped catalyst support. A treated catalyst support is thereby produced. Carrier liquid is removed from the slurry to obtain a dried treated catalyst support, which either directly constitutes the catalyst precursor, or is optionally calcined to obtain the catalyst precursor.
