Selective catalytic reduction (SCR) is an effective technique to reduce nitrogen oxides (NOx) from diesel engine emissions. In this study, a simple reaction model for predicting DeNOx performance deactivation and NH3 slip on a vanadia-based commercial catalyst is developed to evaluate the effects of the gas component and temperature, and NH3/NO feed ratio. This model predicted that NOx conversion rate does not depend on the catalyst temperature when the feed ratio becomes small. The calculation results at 250 deg. indicated that high excess air ratios and low NO and SO2 concentrations suppress the DeNOx performance deactivation. It was also shown that keeping the NH3/NO feed ratio small is necessary to avoid NH3 slip.
