摘要
本文以喹啉为模型化合物,考察了钛的不同引入量对Ni2P催化剂加氢脱氮(HDN)性能影响,通过表征发现少量钛的引入影响了Ni2P前体的还原性能。同时,钛的引入也提高了Ni2P催化剂的加氢脱氮性能.随着钛引入量的增加,加氢脱氮活性出现先增加后降低的趋势,当Ti/Ni摩尔比为0.02时,Ti0.03Ni_2P表现出最高的加氢脱氮活性。
Based on quinoline as model compounds,hydrodenitrogeneration(HDN)performance was investigated on Ni_2P catalyst with the different amount of titanium.The results indicatedthe Ni_2P reduction performance was significantly influenced and hydrodenitrogeneration performance was improved by a small amount of titaniumadded.HDNactivity is decreasesafter increasing with the increasing amount of titanium.When the Ti/Ni molar ratio is 0.03,Ti0.03Ni2Pexhibit the highestHDN activity.
