Abstract

The influence of pore regularity in Fischer–Tropsch synthesis over Co/SiO2 catalysts was investigated by using two series of silica with comparable pore sizes: mesoporous silica (SBA-15) and amorphous silica. It was found that cobalt dispersion was largely influenced by the support porous structure. The cobalt particles on mesoporous silica showed much more homogeneous size distribution and the increase of cobalt loadings did not result in a noticeable increase of Co3O4 particle size on SBA-15, while most of those on amorphous silica agglomerated into clusters. As a result, SBA-15 supported Co catalysts showed higher cobalt-time yield and C5+ selectivity in Fischer–Tropsch synthesis, particularly higher C12–18 fraction. However, the average particle size of Co3O4 supported on amorphous silica increased with the cobalt loadings, which led to lower cobalt-time yield and higher CH4 selectivity.
