A sulfided Mo/γ-Al_2O_3 catalyst was characterized by low-temperature FTIR spectroscopy of adsorbed carbon monoxide, with its HDS activity being investigated with thiophene as a mold substrate. On the basis of the results here, the conclusion may be obtained that the sites for CO adsorption should be the active reaction centers of thiophene HDS.
