Abstract: 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.

Key words: coal-tar, hydrodenitrogenation, reaction network, catalysts
