摘要

为有效解决大气污染物之一NOx,对比了NH3-SCR脱除技术和非氨法脱除技术,阐述并归纳了低温NH3-SCR技术的反应机理和技术特点,介绍了低温NH3-SCR技术耦合不同催化剂时脱除氮氧化物的研究进展,并分析其优缺点,对低温NH3-SCR脱除大气中氮氧化物技术的发展方向进行展望.

Abstract

In order to effectively solve one of the air pollutants,NOx,the NH3-SCR removal technology and non-ammonia removal technology were compared,the reaction mechanism and technical characteristics of low temperature NH3-SCR technology were expounded and summarized,the research progress of nitrogen oxide removal by low temperature NH3-SCR technology coupled with different catalysts was introduced,and its advantages and disadvantages were analyzed.The development direction of low temperature NH3-SCR for removal of nitrogen oxides in the atmosphere was prospected.
