摘　　要：综述了酸精制、溶剂萃取精制、氧化法、离子液体、络合萃取、吸附精制、生物法及组合工艺等多种非加氢脱氮工艺,并分析了各种工艺的优劣及未来发展的方向。酸精制、溶剂萃取、氧化精制工艺因污染大、选择性差及工序复杂等原因,单独应用前景相对较差;离子液体、络合萃取、吸附精制、生物法均在脱氮领域具有各自的优势,多种工艺有机组合使用是非加氢脱氮工艺未来发展的必然趋势。A variety of non-hydrogenation denitrification processes such as acid refining,solvent extraction refining,oxidation,ionic liquids,complex extraction,adsorption refining,biological methods and combined processes are reviewed,the advantages and disadvantages of each process and the future development direction are analyzed.As for acid refining,solvent extraction refining,oxidation non-hydrogenation denitrification process due to high pollution,poor selectivity and complex process,the prospect of single application is relatively poor.Ionic liquid,complex extraction,adsorption refining,biological process non-hydrogenation denitrification process have their own advantages,the combination of various processes is an inevitable trend.
