摘要：
The Fe-Co-Mn/MgO catalyst was prepared using co-precipitation procedure; effects of reaction conditions on the catalytic performance for Fischer-Tropsch synthesis have been investigated. Experiments were carried out under a wide range of reaction conditions including reaction temperature of 473-6731 K, pressure of 1-10 bar, H-2/CO feed molar ratio of 1-4 and space velocity of 3150-7200 h(-1). We also reported further results regarding the effect of various operational conditions on different surface reaction rates. It was found that the optimum operational conditions are H-2/CO = 2/1, GHSV = 4500 h(-1), T = 573 K and P = 1 bar. Characterization of both precursor and calcined catalysts was carried out using XRD, SEM, BET and TPR. (C) 2012 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
