ABSTRACT:
A process for preparing a cobalt based catalyst precursor includes, in a support impregnation stage, impregnating a coated catalyst support comprising porous catalyst support particles coated with carbon, with a cobalt salt, and partially drying the impregnated support. Thereafter, in a calcination stage, the partially dried impregnated support is calcined, to obtain the cobalt based catalyst precursor. The cobalt based catalyst precursor can then, in a reduction stage, be reduced to obtain a cobalt based Fischer-Tropsch catalyst.
