Effect of process conditions on the surface reaction rates and catalytic performance of MgO supported Fe-Co-Mn catalyst for CO hydrogenation
E-mail:
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 473.673 K, pressure of 1-10 bar, H2/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 H2/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.
