Abstract: Novel cobalt catalysts supported on MSU-1 and SBA-12 are developed for F-Tsynthesis in a fixed bed reactor, and the reactivity of Co/MSU-1 and Co/SBA-12 is compared with that of Co/HMS. It is found that the selectivity of C19+ hydrcarbon product for Co/MSU-1 and Co/SBA-12 is higher than that of Co/HMS and the chain propagation ability of Co/MSU-1 and Co/SBA-12 is higher than that of Co/HMS. The results of XRDand N2 adsorption-desorption show that the mesoporous structure of Co/HMS collapses after F-Tsynthesis, but that of Co/MSU-1 and Co/SBA-12 is partly kept, the relative stable mesostructure may be benificial to the product chain propagation.

Key words: MSU-1, SBA-12, Fischer-Tropsch synthesis, Cobalt based catalyst, Hydrocarbon distribution
