This article summarises the abatement of NO(x) pollution by using sorbing catalytic materials with special relevance to the challenge presented in fixed installations sources. A general vision of the origins of the different pollutants, with emphasis on nitrogen oxides formation, is presented as introduction. The impact of NO(x) pollution comprises additionally a quick view of its toxicity and environmental effects. Actual solutions are presented especially the case of the selective catalytic reduction (SCR) process with its advantages and difficulties. The new concepts for NO(x) abatement are also analysed. In such a way, updated information on solid sorbents for NO(x) removal is provided by including metal oxides, spinelles, perovskites, double-layered cuprates, zeolites, carbonaceous materials, heteropolyacids (HPAs), and supported heteropolyacids. The possibility of reducing those sorbed NO(x) is also underlined. Sorption mechanisms are analysed and clarified by emphasising convergence and disagreement points.
本文总结了使用吸附催化材料减少氮氧化物(NO(x))污染的情况,特别涉及固定装置源所面临的挑战。作为引言,介绍了不同污染物的来源概况,重点是氮氧化物的形成。此外,还简要介绍了NO(x)污染的影响,包括其毒性和环境效应。文中介绍了实际的解决方案,特别是选择性催化还原(SCR)工艺的情况及其优缺点。还分析了减少NO(x)的新概念。通过纳入金属氧化物、尖晶石、钙钛矿、双层铜酸盐、沸石、碳质材料、杂多酸(HPA)和负载型杂多酸,提供了关于用于去除NO(x)的固体吸附剂的最新信息。还强调了还原那些吸附的NO(x)的可能性。通过强调共同点和分歧点,对吸附机理进行了分析和阐明。
