| 摘 要： | 设计实验证明了Ni2P和MoS2催化剂在喹啉加氢脱氮反应中存在协同效应,该协同效应能够用氢溢流遥控模型理论解释。Ni2P//MoS2的协同因子随反应温度升高而减小,并且略微大于相同反应条件下NiSx//MoS2的协同因子。Ni2P产生的溢流氢能够提高MoS2催化剂上加氢活性位的数量,促使Ni2P//MoS2催化体系增加1,2,3,4-四氢喹啉和5,6,7,8-四氢喹啉加氢生成十氢喹啉的速率,提高其脱氮活性;因此,Ni2P对MoS2催化剂是很好的助剂。

| Abstract: | The synergetic effect between Ni2P/Al2O3 and MoS2/Al2O3 catalysts on their performance in the hydrodenitrogenation of quinoline was proved by a simplified experimental design and explained by the remote control model through a migration of hydrogen spillover. The results indicated that the synergism factor of Ni2P and MoS2 is slightly higher than that of NiSx and MoS2; it decreases with the increase of reaction temperature. Since the spillover hydrogen with Ni2P can increase the amount of hydrogenation active sites of MoS2, the hydrogenation rate of 1,2,3,4-tetrahydroquinoline and 5,6,7,8-tetrahydroquinoline to decahydroquinoline over the Ni2P/Al2O3 and MoS2/Al2O3 catalyst system is then greatly enhanced; as a result, Ni2P is a superior promoter for MoS2 catalyst for hydrodenitrogenation. |
