Abstract
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.关键词
