Abstract: The concentration of active sites for catalysts of CoO—MoO_3/r-Al_2O_3,CoO—MoO_3—TiO_2/r-Al_2O_3 series were characterized by the dynamic oxygen chemisorption amounts (DOC) at ambient temperature. The directly proportional correlations between HDS activities K_(HDS)and DOC amounts were found well. The DOC Characteri zation may be considered as a practical method in the determination of HDS activities for catalysts of Co—Mo series.
