Catalytic Performances of Alumina-Supported CoMo Catalysts in HDS of FCC Diesel: Comparison Between Gamma, Delta and Theta-Alumina

Different transitional alumina including gamma, delta and theta-alumina have been used as  the supports of  HDS catalysts ,which were rarely reported.The effect of the nature of alumina supports on metal–support interaction and activity of the corresponding CoMo catalysts were studied systematically.
