钒系脱硝催化剂的研究现状及发展趋势

摘要

The fundamental principle of the SCR De-NOx was introduced. Current research and development situation of V2O5/TiO2,V2O5/SiO2,V2O5/activated coke SCR catalyst were elaborated,the reaction mechanism of V2O5 SCR De-NOx was discussed. In the end,the research direction and future development trend of vanadium catalysts for De-NOx were prospected,such as increasing activity and selectivity of low temperature,developing new type V2O5 catalyst with high activity and better anti-poisoning ability ,and so on.%概述了选择性催化还原(SCR)脱硝的技术原理。重点综述了V2O5/TiO2、V2O5/SiO2、V2O5/AC等钒系脱硝催化剂的研究现状，探讨了钒系SCR催化剂脱硝的作用机理。最后展望了钒系脱硝催化材料的发展趋势，主要是提高低温活性和选择性、研制抗中毒能力强的催化剂和开发新型高效钒催化剂等。
