A cobalt containing catalyst supported on a metal oxide suitable for performing a Fischer-Tropsch reaction. A pore volume of a metal oxide support, before loading of cobalt thereon, is within the range of 0.35 to 0.6 cc/g. The support has an average pore diameter before the cobalt loading and reduction such that the effective average pore diameter after cobalt loading and reduction is 14 nanometers or higher. A cobalt loading of 11 weight % or higher is also provided. An alpha value higher than 0.89 in a diesel to wax weight ratio below 1.07 is provided.
