摘要 随着全球碳中和行动陆续推进,氨以其优异的综合性能成为实现“碳中和”过程中最具优势的零碳燃料之一。氨在实际燃烧过程中会产生一定数量的污染物(NO_(x)、N_(2)O和NH_(3)等),需对尾气进行处理后排放,氨燃烧尾气排放特性及相关污染物脱除方法是其尾气处理技术开发的关键依据。通过对国内外文献资料的梳理总结,介绍氨燃烧反应原理,对当前氨燃烧尾气排放特性的研究进行分析,针对污染物NO_(x)和N_(2)O分别综述了其脱除方法及对应的高效催化剂,最后对氨燃烧尾气处理方案进行概述。 With the advance of global carbon neutrality,ammonia has become one of the most advantageous zero-carbon fuels in the process of"carbon neutrality"due to its excellent comprehensive performance.A certain amount of pollutants(NO_(x),N_(2)O and NH_(3),etc.)will be produced in the actual combustion process of ammonia,which should be treated and discharged.The exhaust gas emission characteristics of ammonia combustion and the removal method of related pollutants are the basis for the development of its exhaust gas treatment technology.Through the review and summary of domestic and foreign literature,the principle of ammonia combustion reaction is introduced,the current researches on the emission characteristics of ammonia combustion are analyzed,the reduction methods of NO_(x)and N_(2)O and the corresponding efficient catalysts are overviewed respectively,and the treatment schemes of ammonia combustion exhaust gas are summarized.
