摘　　要：在“双碳”背景下,以硝酸、己二酸为代表的化工生产环节中产生的温室气体N_(2)O及随之一起排放的NH_(3)、NOx、VOCs等气体污染物的减污降碳协同净化技术备受关注。本文总结了近年来化工尾气中上述单一气体污染物净化技术以及N_(2)O与其他气体污染物协同净化技术的研究成果,探讨了其工业化应用实绩,并对该领域未来的研究方向进行了展望。指出,未来应致力于提高该技术催化剂的低温活性和抗毒性,构建分子筛催化剂结构与催化活性之间的关系,以及不断推进该技术的工业化应用进程。Under the background of“carbon peaking and carbon neutrality goals”,significant attention was drawn to the collaborative purification technology for the reduction of greenhouse gas N_(2)O produced in chemical production(such as nitric acid and adipic acid)and other accompanying gas pollutants(NH_(3),NOx,VOCs).This study summarized the latest research progress in the purification technology of the aforementioned single-component exhaust gas and collaborative purification technology for the reduction of N_(2)O and pollutants in chemical exhausts.The industrialization performance was also discussed.Prospects were envisioned for future research directions in this field.It was pointed out that future focus should be put on improving the low-temperature activity and anti-toxicity of the catalysts in this fieldand establishing a relationship between the structure of zeolite catalysts and their catalytic activity.Furthermore,the industrial application process of this technology should be continuously advanced.
