Co/ZrO₂-Al₂O₃ Catalysts with Bimodal Pore Distribution for Fischer-Tropsch Synthesis

Abstract:

The Co/ZrO2-Al2O3 catalysts were prepared by impregnation method, and characterized via quantitative XRD, H2-TPR, and N2 adsorption-desorption techniques. The study showed that the addition of ZrO2 increased the interaction between active component and support, decreased the average crystallite size of Co3O4 and improved its dispersion. The performance tests presented that the Co/ZrO2-Al2O3 catalysts with bimodal pore distribution had high CO conversion and were more selective towards the gasoline fraction (C5-C10) and diesel fraction (C11-C18).
