| 摘 要： | 介绍了柴油超深度加氢脱硫（HDS）机理及氮化物对其的影响。介绍了硫化物存在形式、相对反应速率及其HDS反应路径。结果表明：非噻吩类硫化物HDS活性较高,在加氢催化剂活性中心上直接氢解生成相应的烃和H2S;催化剂的酸性在加氢精制工艺中对裂化反应有促进作用,必须考虑到脱硫率和催化剂寿命的最优化选择;碱性氮化物比非碱性氮化物对HDS的抑制作用强,不同催化剂的抗氮化物毒化能力不同,氮化物对HDS的两种路径影响不同,对加氢（HYD）路径的抑制作用强于直接氢解（DDS）路径;柴油馏分超深度HDS机理及氮化物对其抑制机理的研究,可以指导高活性、抗抑制剂催化剂的开发,从而缓和工艺条件,延长催化剂寿命。

| Abstract: | The mechanisms of diesel ultra-deep desulfurization and impact of nitrogen compounds are introduced.The forms of nitrogen compounds,the relative reaction rate and HDS reaction route are specifically studied.The results show that the non-thiophene sulfides have a higher HDS activity,which can directly be hydrogenolyzed into hydrocarbons and H2S on the active site of hydrogenation catalysts.As the acid site of catalyst has a promoting effect on cracking reaction in hydrogenation process,the desulfurization ra... |
