采用程序升温还原法制备Ni-Mo-P/Al2O3-ZrO2催化剂.运用XRD和IR技术对催化剂和载体进行表征.考察Ni-Mo-P/Al2O3-ZrO2催化剂对噻吩加氢脱硫、吡啶加氢脱氮的催化性能.结果表明,在Al2O3表面引入少量ZrO2,可以减弱P和Al2O3的强相互作用,抑制MPO4的生成.添加适量的助剂Mo,催化剂噻吩加氢脱硫、吡啶加氢活性均有不同程度的提高.%Ni-Mo-P/Al2O3-ZrO2 catalysts were prepared by temperature-programmed reduction in a H2 flow. The supports and catalysts were characterized by XRD and IR. Hydrodesulfurization of thiophene and hydrodenitro-genation of pyridine catalyzed by Ni-Mo-P/Al2O3-ZrO2 catalysts was carried out in a high pressure fixed bed reactor. The experimental results show that the introduction of small amounts of ZrO2 on the surface of A12O3 would reduce the strong interaction of P with A12O3, and therefore, inhibites the formation of A1PO4. And the catalytic activity of thiophene hydrodesulfurization and pyridine hydrodenitrogenation over the catalyst are improved with the adding of appropriate amount of Mo.
