Abstract:
1. A process for producing a supported cobalt-based Fischer-Tropsch synthesis catalyst, which process includes in a first activation stage, treating a particulate supported cobalt-based Fischer-Tropsch synthesis catalyst precursor comprising a catalyst support impregnated with cobalt and containing cobalt oxide, with a hydrogen-containing reducing gas or a nitrogen-containing gas, at a first heating rate, HR1, until the precursor has reached a temperature, T in a second activation stage, treating the partially treated catalyst precursor with a hydrogen-containing reducing gas, at a second heating rate, HR2, where 0≦HR2<HR1, for a time, t in a third activation stage, treating the partially reduced catalyst precursor with a hydrogen-containing reducing gas, at a third heating rate, HR3, where HR3>HR2 until the partially reduced catalyst precursor reaches a temperature, T
