The activities of hydrodesulfurization(HDS)and hydrogenation(HYD)for UFPAl2O3 catalysts prepared by two methods,impregnation and supercritical fluid drying process,were determined in a continuous flow microreactor. It is shown that the catalytic properties and the dispersion of Mo species on alumina surface are greatly affected by the preparation method,as compared to that of ordinary Mo/Al2O3(prepared by impregnating ordinary γ-Al2O3 with molybdenum salt),the HDS activities of UFP-Mo/Al2O3(prepared by impl...
