NOx是主要的大气污染物之一。目前SCR（选择性催化还原脱硝技术）是最有效、发展最为成熟、应用最多的一种烟气脱硝技术。本文对以V2O5催化剂活性组分、NH3为还原剂的SCR反应进行了动力学模拟，分析了反应动力学中氨氮比、温度对反应的影响；发现了在反应进行的过程中孔道1/3处反应比较剧烈，比较适宜的反应温度为700K左右，随着氨氮比的增加，适宜的反应温度范围越来越小，适宜的氨氮比范围在1.3～1.4之间；随着反应温度的升高，选择性参数越来越小。

NOx is one of the main atmospheric pollutants. SCR (selective catalytic reduction) is the most effective, mature and most-used flue gas DeNOx technology. Simulation of SCR about reaction kinetics on V2O5 with NH3 as reductant has been studied. During the operation of SCR reaction, the influence of temperature and mole ratio of NH3/NOx of reaction has been analyzed. Results indicate that SCR react sharply in the channel 1/3, more proper temperature is about 700K, as mole ratio of NH3/NOx increases, proper temperature range becomes smaller and smaller; proper mole ratio of NH3/NOx is between 1.3 and 1.4; as the temperature rises, optional parameter becomes smaller.
