  • Construction of model for estimating rate constant of SCR reaction over hydrothermally aged Cu-CHA catalyst

説明

<p>Based on the changes of catalyst properties, a model was constructed to estimate the rate constants of Standard-SCR, NH3 oxidation, and NO oxidation reactions over hydrothermally aged Cu-CHA catalyst. Moreover, the rate constants obtained by the constructed model were applied to the model for estimating NOx conversion over fresh catalyst constructed in previous studies, and the NOx conversion over hydrothermally aged catalyst was estimated. As a result, the calculated NOx conversion over hydrothermally aged Cu-CHA catalyst was in good agreement with the experimental results.</p>
