An investigation of the adsorption of NO on reduced Co-Mo/Al_2O_3 and Ru-Co-Mo/Al_2O_3 catalysts has been performed by using IR and MS spectros-copies, and it was found that two IR bands appeared at 1895 and 1880 cm~(-1) in the IR spectra and three peaks exhibited at 353, 423 and 473 K in the TPD-MS profiles. These are attributed to the various Co-sites on the surface of catalysts.Comparing Co-Mo/Al_2O_3 catalyst with Ru-Co-Mo/Al_2O_3 it was found that the addition of Ru in Ru-Co-Mo/Al_2O_3 markedly led to an increase of the rate and amount for NO adsorption, which may indicate that the HDS activity of Ru-Co-Mo/Al_2O_3 was much higher than that of Co-Mo/Al_2O_3 catalyst.
