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. |
