The catalysts most often used for hydrodesulfurization (HDS) of petroleum fractions are derived from oxides of Co and Mo supported on ..gamma..-Al/sub 2/O/sub 3/, and their surfaces are sulfided prior to operation. The hydrodesulfurization kinetics data reported here were measured to characterize the catalyst operating at about 100 atm and 300/sup 0/C; the reactant stream contained dibenzothiophene (DBT) and hydrogen dissolved in n-hexadecane carrier oil. The results provide an indication of structural variations in the Co-Mo/..gamma..-Al/sub 2/O/sub 3/ catalyst brought about by changes in the reaction environment.
