    摘要
  • 摘要: Co-Ni/Al2O3 catalyst was prepared by the fusion method and used in Fischer-Tropsch synthesis（FTS）. The catalysts were characterized by means of nitrogen sorption and scanning electron microscopy. The effect of some reaction conditions such as temperature，pressure and H2/CO feed ratio on the catalytic performance of Co-Ni/Al2O3 in CO hydrogenation was investigated in a fixed-bed reactor. The results indicate that the optimum reaction conditions are 250 ℃，0.3 MPa，H2/CO feed ratio of 2.0，and GHSV of 3 000 h-1. Kinetically，the reaction rate was correlated with the Langmuir-Hinshelwood-Hougen-Watson type models. The activation energy for the best fitted model is 88.41 kJ/mol，suggesting that the intra-particle mass transport is not significant.
