Abstract:
1. A process for preparing a catalyst precursor, which process includes in a first preparation step, impregnating a particulate catalyst support with an organic cobalt or nickel compound in a carrier liquid, to form an impregnated intermediate and calcining the impregnated intermediate at a calcination temperature which is not above 400° C., to obtain a calcined intermediate; and thereafter, in a second preparation step, impregnating the calcined intermediate from the first preparation step, with an inorganic cobalt or nickel salt in a carrier liquid, to obtain an impregnated support, and calcining the impregnated support, to obtain the catalyst precursor, wherein none of the inorganic cobalt or nickel salt used in the second preparation step is present during the first preparation step.
