摘要：
Based on a model of progressive shell poisoning for a single catalyst particle and Eley-Rideal mechanism of selective catalytic reduction (SCR) reaction, the K-poisoning kinetics of granular V2O5/TiO2 catalysts was studied and their K-poisoning kinetic equation was established. Combining the retention activity of the catalysts from the model simulation with that from the experiments, the relation between K loadings over the catalysts and reaction time was established. The combined effect of K concentration in flue gas and K-poisoning reaction rate constant of the catalysts on the retention activity of the catalysts was simulated based on the established model. The simulated results are in good agreement with the reported operating results of catalysts. This indicates that the established kinetic model on K-poisoning for V2O5/TiO2 catalysts is rational. © 2014 Chinese Society for Electrical Engineering.
