摘要/Abstract

摘要： 氮氧化物(NO_x )严重威胁人体健康和生态环境。随着火电行业烟气NO_x 初步实现超低排放，非电行业烟气NO_x 排放控制成为重中之重。NH₃ 选择性催化还原NO_x 是最有效的NO_x 控制技术。非电行业烟气含有SO₂ 、碱性物质以及重金属等杂质，易导致催化剂中毒失活。针对NO_x 净化催化剂低温活性不足、SO₂中毒、碱金属中毒以及复合中毒等关键难题，文章综述了各类低温抗中毒NOx 净化催化剂的研究进展，总结了提高催化剂的低温活性、抗SO₂ 中毒、抗碱金属中毒以及抗复合中毒的策略。文章为开发低温抗中毒NOx 净化催化剂提供了研究思路，为推进NO_x 净化催化剂在非电行业烟气NOx 净化中的实际应用提供理论指导。

Abstract: Nitrogen oxides (NO_x) threaten to the human health and ecological environment. As the gradual realization of ultra-low
emission of NO_x in thermal power industries, the emission reduction of NO_xin non-electrical industries becomes urgent. Selective
catalytic reduction of NO_x by NH₃ is the most effective NO_x control technology. The flue gas of non-electrical industries generally
contains SO₂ , alkali and heavy metals that easily lead to the catalyst inactivation. In view of the key problems of NO_x reduction
catalysts such as the poor low-temperature activity, SO₂ -poisoning, alkali-poisoning, and the multiple poisonings, this paper reviews
the research progress of various low-temperature poisoning-resistant NO_x reduction catalysts, and summarizes the strategies for
improving the low-temperature activity, SO₂ -resistance, alkali-resistance, and multiple resistance of catalysts. This paper proposes
research strategies for developing low-temperature poisoning-resistant NO_x reduction catalysts, and provides imperative guidance for
the practical application of NO_xreduction catalyst in non-electrical industries.
