Patent ID: 11865523

Abstract:
A cobalt catalyst precursor is described comprising cobalt oxide crystallites disposed within pores of a titania support, wherein the cobalt oxide crystallites have an average size as determined by XRD in the range 6 to 18 nm, and the titania support is a spherical titania support with a particle size in the range 100 to 1000 μm, wherein the catalyst precursor has a pore volume of 0.2 to 0.6 cm3/g and an average pore diameter in the range 30 to 60 nm, and wherein the catalyst precursor has a ratio of the average cobalt oxide crystallite size to the average pore diameter in the range 0.1:1 to 0.6:1. The catalyst precursor may be reduced to provide catalysts suitable for use in Fisher-Tropsch reactions.
