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),andcharacterized byN2physisorption, CO chemisorption, TPR, TPD, XRD and SEM techniques. The performance of catalysts was tested in a fixed bed reactor system under the conditions of 240°C, 2.5MPa, H2/CO feed molar ratio of 2.0 for 100 h, and compared with those of Co/SiO2 catalyst.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 catlyst can be used as FT catalyst for GTL process applications.
