Abstract
For increasing the hydrothermal stability and acidity, the Cobalt catalyst supported on mesoporous silica hollow sphere (Co/SHS) was prepared for Fischer-Tropsch Synthesis (FTS), and characterized by N2 physisorption, CO chemisorption, TPR, TPD, XRD and SEM. The performance of these catalysts for FTS were tested in a fixed bed reactor under the conditions of 240℃, 2.5MPa, H2/CO feed molar ratio of 2.0 for 100 h, and compared with those of Co/SiO2 catalyt. The dependence of crysrallite size and reducibility of Co3O4 on the supports were investigated with conversions of CO and H2, liquid fuel selectivity and product distribution in a fixed bed reactor system. The Co/SHS catalyst showed higher FTS activity and liquid fuel productivity for the middle distlilate than Co/SiO2 catalyst. The results suggest that the Co/SHS catalyst can be used as FT catalyst for GTL Process applications.
