摘    要:研究了Al_2O_3,TiO_2-Al_2O_3等载体对Au-Pd双金属催化剂的噻吩加氢脱硫性能的影响,并运用XRD,TPD,BET,TPR等手段对Au-Pd双金属催化剂进行了表征.结果表明,Au-Pd/TiO_2-Al_2O_3催化剂有较好的噻吩加氢脱硫反应活性和稳定性,与Au-Pd/Al_2O_3催化剂相比,Au-Pd/TiO_2-Al_2O_3催化剂有较高的酸密度和酸强度、活性表面积、H_2及CO的吸附量.

关 键 词:Au-Pd  TiO_2-Al_2O_3  载体  加氢脱硫

Abstract:The gold catalyst can be used in the thiophene hydrodesulfurization reaction. The effects of Al_2O_3,TiO_2-Al_2 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.
Keywords:Au-Pd Catalyst  TiO_2-Al_2O_3  Supports  HDS
