摘　　要：S、N的脱除是煤直接液化油加工的重要方面,为了更好的对煤液化油进行加工利用,系统分析了目前煤液化油加氢脱硫脱氮的研究。主要从油品组分、实验室反应条件和工艺以及动力学4个方面进行了介绍。结果发现:石油行业中关于含硫氮化合物的分析手段(如GC-AED、GC-PFPD)可以进一步与煤液化油的脱硫脱氮实验研究结合起来,这有利于液化油中S、N的脱除;目前关于液化油加氢工艺条件的研究数据公开不多,反应动力学方面的研究缺乏充足的数据支持,由于催化剂对工艺的影响研究较少,但催化剂技术已有了很大发展,可以考虑将新型催化剂引入反应中。HDS （desulfuration） and NDN （denitrification） are the most important process of coal direct liquification oil treatment. In order to better process and utilize the coal direct liquifieation oil, introduce the former relevant studies from the aspects of oil quality analysis, reaction conditions and technological process in laboratory, dynamics. The analysis show that the analysis methods of sulphur and nitrogen （such as GC-AED, GC-PFPD） applied to oil industry can be furthur combined with experimental study, which is more favorable for HDS and NDN. The research about catalytic HDS and NDN of coal direct liquefaction oil are so inadequate that the reaction dynamics lacks adequate data. The catalyst technology has made great progress, but its application in HDS and NDN is less. So further study on this field with the new catalysts would has broad prospect.
