| 摘 要： | 对分层装填的Ni2P//MoS2催化剂上的二苯并噻吩加氢脱硫反应进行了研究。结果表明,分层装填的Ni2P/Al2O3和MoS2/Al2O3催化剂在二苯并噻吩加氢脱硫反应中存在氢溢流效应,氢溢流有助于提高MoS2催化剂的活性位密度和加氢脱硫反应速率。由于Ni2P比NiSx具有更强的氢分子解离能力,Ni2P//MoS2催化体系的氢溢流因子略高于NiSx//MoS2;相对于NiSx,Ni2P对MoS2催化剂是更好的助剂。

| Abstract: | The hydrodesulfurization of dibenzothiophene over physically separated Ni2P//MoS2 catalyst beds was investigated.The results indicated that the hydrogen spillover effect appears between the Ni2P/Al2O3 and MoS2/Al2O3 catalysts in the hydrodesulfurization reaction, which can significantly enhance the concentration of active sites and the hydrodesulfurization rate over the MoS2 catalyst. The spillover factor on Ni2P//MoS2is slightly higher than that on NiSx//MoS2, due to the higher hydrogen dissociation activity of Ni2P; as a result, Ni2P is a superior promoter to NiSx for the MoS2 catalyst. |
