摘　　要：煤焦油加氢精制生产车用燃料是提高煤焦油附加值及煤焦油清洁利用的有效手段,煤焦油中含氮化合物复杂多样,如何高效脱出含氮化合物中的氮原子是开发煤焦油加氢脱氮催化剂的研究重点。本文简述了煤焦油中含氮化合物的分布情况及特点,综述了煤焦油中吡啶、喹啉、吲哚等典型含氮化合物的加氢脱氮反应网络的研究现状;加氢脱氮催化剂的研究现状从加氢脱氮反应机理、活性组分、载体、助剂4个方面进行了论述。最后针对煤焦油中含氮组分复杂多样的特性提出了研发高效煤焦油加氢脱氮催化剂的一些新方向。Coal-tar hydrogenation for refining motor fuel is an effective method to improve its additional value and clean utilization. As nitrogen compounds in coal-tar are complex, how to effectively remove N atom in nitrogen compounds is the research focus on the development of coal-tar hydrodenitrogenation（HDN） catalyst. The distribution and characteristics of nitrogen compounds in coal-tar are introduced, and the reaction network of typical coal-tar nitrogen compounds are discussed, including pyridine, quinoline, and indole. The research status of HDN catalyst is summarized from four aspects, which are HDN reaction mechanism, active components, carriers and promoters. Then, suggestions on the R＆D of highly efficient HDN catalyst in coal-tar are proposed.
