【Abstract】 The gold catalyst can be used in the thiophene hydrodesulfurization reaction. The effects of Al₂O₃,TiO₂-Al₂ O 3 etc supports on HDS activity of Au-Pd catalysts were studied, and also characterized with XRD, TPD, BET, and TPR. The results indicate that Au-Pd/TiO 2 -Al 2 O 3 catalyst has better hydrodesulfurization activity and stability than those of Au-Pd/Al 2 O 3 catalyst. Compare with Au-Pd/Al 2 O 3 catalyst, Au-Pd/TiO 2 -Al 2 O 3 catalyst has higher acid site density and acid strength, active surface area and absorbing amount of H 2 and CO.更多还原
