| 摘 要： | 选择性催化还原NOx是处理工业废气和稀燃汽车尾气NOx的有效方法。由于还原剂甲烷廉价易得，甲烷选择性催化还原NOx（简称CH4-SCR）已成为近年来的研究热点，而分子筛类催化剂因催化活性高而得到广泛研究。本文综述了CH4-SCR脱除NOx体系中不同金属负载的分子筛催化剂及反应机理方面的研究进展，包括Co系、Pd系、In系等分子筛催化剂在催化性能、反应机理及掺杂改性等方面的研究现状，并提出了分子筛类催化剂用于CH4-SCR的研究方向。

| Abstract: | Selective catalytic reduction of NOx is an efficient technique to remove NOx in the presence of excess oxygen for both stationary and mobile sources.Selective catalytic reduction of NO with methane(CH4-SCR)has received considerable attention because methane is low cost and easily obtained.Characterized with high catalytic activity,zeolite-based catalysts have been widely studied.In this paper,the advances in zeolite-based catalysts for CH4-SCR are reviewed,with focus on catalytic activity,reaction mechanism... |
