Ru/Al/sub 2/O/sub 3/ and Ru-Mo/Al/sub 2/O/sub 3/ catalysts have been prepared by impregnating respectively ..gamma..-Al/sub 2/O/sub 3/ and calcined Mo/Al/sub 2/O/sub 3/ with aqueous solutions of ruthenium (III) acetate. XPS spectra of catalysts dried at 393 K, calcined in air at 873 K, and sulfided in H/sub 2//H/sub 2/S are reported. Ru and Mo species in the catalysts, according to the respective binding energies, were ruthenium dioxide and oxomolybdenum (VI) in catalysts calcined at 873 K and a ruthenium sulfide and MoS/sub 2/ in the sulfided catalysts. Unusually low Ru binding energies were found for some catalysts. The properties of the catalysts in thiophene HDS are interpreted with the aid of the XPS results.
