摘要：

The influence of the Co/SBA-15 catalyst texture, such as pore size and pore length on Fischer-Tropsch (FT) Synthesis, was investigated in this paper. The morphology, structure, and microstructures of Co/SBA-15 catalysts were characterized by SEM, Brunauer-Emmett-Teller (BET), TPR, HRTEM, and XRD. The experimental results indicated that the increase of pore size could improve the activity of the Co/SBA-15 catalyst, and the further increase of pore size could not significantly promote the activity. Moreover, it was also found that the pore length of the Co/SBA-15 catalyst played a key role in the catalytic activity. CO2 and C4+ selectivity were 2.0% and 74% during the simulated syngas (64% H-2: 32% CO: balanced N-2) FT over the Co/SBA-15 catalysts, and CO conversion rate and CH4 selectivity were 10.8% and 15.7% after 100 h time on stream.
