제목 Studies on Fischer-Tropsch synthesis over cobalt based supported catalysts
초록 Recently, gas to liquid (GTL) process has been received much attentions because of high oil prices and global warning. Cobalt based catalysts are receiving widespread attention as the preferred Fischer-Tropsch synthesis (FTS) catalysts for GTL process. The cobalt-based catalysts supported on Al2O3 and modified Al2O3 were prepared by impregnation method and characterized by N2-adsorption, XRD, SEM, TEM, and TPR techniques. The broadening of XRD peak revealed nanosized Co3O4 crystallites less than 7nm. TEM data showed the nanosized particles (<5nm) of Co3O4 crystallites. The performance of these catalysts for FTS were tested in a fixed bed reactor under the conditions 240oC, 2.5MPa, H2/CO feed molar ratio of 2.0 for 40h. The dependence of crysrallite size and reducibility of Co3O4 on the supports were investigated with FTS activity, CO conversion and product distribution in a fixed bed reactor system.
