|Title:||Effect of supports on HDS activity of Au-Pd catalysts|
|Series/Report no.:||Int. Cl. ⁸ B01J23/44; B01J23/52; C10G25/05|
|Abstract:||The Au-Pd catalysts have been used successfully for thiophene hydrodesulfurization (HDS). The effects of Al₂O₃, TiO₂-Al₂O₃, ZrO₂-Al₂O₃ and CeO2-Al₂O₃ supports on HDS activities of Au-Pd catalysts have been investigated. The results show that Au-Pd catalysts supported on mixed oxide exhibit much higher HDS activity and stability than that of the Au-Pd/Al₂O₃ catalyst. TiO2-Al₂O₃ is the best support among these mixed oxides. As compared with Au-Pd/Al₂O₃ catalyst, Au-Pd/TiO₂-Al₂O₃ catalyst has higher acid density and acid strength, and active surface area to absorb higher amounts of H₂ and CO.|
