In this work, a kinetic study of the selective catalytic reduction of NO with NH3 has been carried out. After proving the operating condition that the effect of intraphase diffusion and interphase mass-transfer processes can be ignored, the selective catalytic reduction of NO with NH3 on the catalytic activity of V2O5-WO3/TiO2 has been carried out with fixing the feed gas flow rate and composition ( NO, NH3, O2 ) while varying the catalyst loading. Based on the experimental results of NO removal efficiency, the empirical catalytic reaction rate equation of NO with NH3 has been obtained using differential analysis. The experimental result is further proved by the graphic integral method at the temperature from 320℃to 400 ℃ The reaction order is 1 to NO and zero to NH3. The reaction follows the Eley-Rideal mechanism model.  相似文献
