Abstract: A process for preparing a cobalt-based Fischer-Tropsch synthesis catalyst includes introducing a soluble modifying component precursor of the formula Mc(OR)x, where Mc is a modifying component selected from the group comprising Si, Ti, Cu, Zn, Zr, Mn, Ba, Ni, Na, K, Ca, Sn, Cr, Fe, Li, Tl, Sr, Ga, Sb, V, Hf, Th, Ce, Ge, U, Nb, Ta, W or La, R is an alkyl or acyl group, and x is an integer having a value of from 1 to 5, onto and/or into a cobalt-based Fischer-Tropsch synthesis catalyst precursor, which comprises a porous pre-shaped catalyst support supporting cobalt in an oxidized form. The resultant modified cobalt-based Fischer-Tropsch synthesis catalyst precursor is reduced to obtain a cobalt-based Fischer-Tropsch synthesis catalyst.

Abstract: This invention relates to methods of minimizing catalyst degradation during the handling of a catalyst used in a slurry phase reactor. The methods include catalyst handling steps such as catalyst loading into a slurry phase reactor, slurry phase reactor start-up, slurry phase reactor shut-down, and slurry phase reactor unloading when catalyst reloading is envisaged. In the method of loading the slurry phase reactor, a slurry of wax and catalyst is formed in a loading vessel. Clean molten wax is formed in the reactor, syngas is pumped through the clean molten wax in the reactor, and the slurry from the loading vessel is transferred to the reactor.
