Effect of Cobalt and Zinc Precursor Loading on the Catalyst Activity of Fischertropsch Synthesis

Five samples of Co-Zn/SBA-15 catalysts were prepared using wet impregnation method with different composition of cobalt loading (5, 10 and 15 wt % Co) and zinc loading (5, 10 and 15 wt % Zn) and were investigated with respect to physical and chemical properties as well influence on activity and sele...
