摘　　要：烟气脱硫脱硝反应动力学模型分为经验速率模型和机理模型两大类,经验速率模型建立相对简单,但无法深入描述反应机理,机理模型能够深入描述反应路径,但计算较复杂,二者皆有利弊,目前仍有大量学者应用反应动力学模型或将其作为辅助阐释反应机理。介绍了烟气脱硫脱硝反应动力学相关模型的建立原理,综述了吸附材料(活性炭、沸石等)在脱硫脱硝中的应用,分析了两种模型的优缺点,并提出未来需结合多模型与检测技术,以明晰复杂烟气中多组分反应机制,为技术优化提供理论支撑。The reaction kinetics model of flue gas desulfurization and denitrification is divided into two categories:empirical rate model and mechanism model,the empirical rate model is relatively simple to establish but cannot describe the reaction mechanism in depth,and the mechanism model can describe the reaction path in depth but the calculation is more complex,both of which have advantages and disadvantages,therefore,there are still a large number of scholars who use the reaction kinetic model or use it as an auxiliary to explain the reaction mechanism.The principle of establishing the kinetic correlation model of flue gas desulfurization and denitrification reaction is introduced,the application of adsorbent materials(such as activated carbon and zeolites)in desulfurization and denitrification is summarized,the advantages and disadvantages of two models are analyzed,and it is proposed that future efforts should combine multiple models and detection technologies to clarify the multi-component reaction mechanisms in complex flue gas.
