Progress in collaborative purification technology for reduction of N2O and other pollutants in chemical exhausts
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 N2O produced in chemical production(such as nitric acid and adipic acid)and other accompanying gas pollutants(NH3,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 N2O 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.
