ni2p和mos2催化剂在喹啉加氢脱氮反应中的协同效应
, PP. 698-702
Keywords: 氢溢流,协同效应,加氢脱氮,mos2,ni2p,喹啉
Abstract:
？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。
