Abstract:
1. A process for preparing a cobalt based Fischer-Tropsch synthesis catalyst precursor, which process includes introducing a multi-functional carboxylic acid having the general formula (I) or a precursor thereof, where C* in each of C*R 1 and C*R 2 is a sp 2 carbon, and R 1 and R 2 are the same or different, and are each selected from the group consisting of hydrogen and an organic group, into and/or onto a particulate catalyst support, with the ratio of the quantity of multi-functional carboxylic acid used relative to the support surface area being at least 0.3 μmol carboxylic acid/m 2 of support surface area; simultaneously with the introduction of the carboxylic acid into and/or onto the catalyst support, or subsequent thereto, introducing a cobalt compound into and/or onto the catalyst support; and calcining the impregnated support to obtain the cobalt based Fischer-Tropsch synthesis catalyst precursor.
