Patent ID: 8084387

Claim:
A cobalt/phosphorus-alumina catalyst for a Fischer-Tropsch reaction in which cobalt is supported on a support as an active component, the catalyst including cobalt (Co) supported on a phosphorus-alumina support in which the phosphorus (P) is supported on an alumina surface, the phosphorus having 0.05 to 20 wt % per 100 wt % of the alumina and the cobalt having 5 to 40 wt % per 100 wt % of the phosphorus-alumina support, and the catalyst having a bimodal pore structure with pores of a relatively smaller size PS 1 and pores of a larger size PS 2 , wherein the pore sizes PS 1 and PS 2 are; 1 nm ≦PS 1 ≦25 nm; and 25 nm <PS 2 ≦150 nm.
