摘要
CH_(4)选择性催化还原氮氧化物(CH_(4)-SCR)是一种潜在的新型脱硝技术。综述了近10年来CH_(4)-SCR脱除NOx体系中不同金属/分子筛催化剂及反应机理方面的研究进展,包括对催化剂反应活性位点、关键活性中间体和反应动力学的新认识,以及分子筛类型、负载金属类型和反应条件等关键因素对CH_(4)-SCR催化性能的影响,并提出了金属/分子筛类催化剂用于CH_(4)-SCR反应的研究展望。
CH_(4) selective catalytic reduction of NOx(CH_(4)-SCR)is a potential technique to remove NOx.In this paper,the research progress of different metal/zeolite catalysts and reaction mechanisms in CH_(4)-SCR in the past ten years was reviewed.The influence factors of CH_(4)-SCR over metal/zeolite catalysts were discussed,including new understandings of catalytic active sites,key active intermediates,reaction kinetics,molecular sieve type,supported metal type and reaction conditions.The application and further research direction on metal/zeolite catalysts of CH_(4)-SCR were proposed.
