摘要

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NiS_x//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 NiS_x 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.
