Following our work on modeling of monolith catalysts, we herein focus on developing a fixed-bed reactor model in the AMESim modeling platform. A kinetic model for NO oxidn. and NOx storage over Pt/Ba/Al2O3 recently developed in the literature was successfully implemented and validated against the exptl. data available in the previous work of Scotti et al.. The oxidn.-storage model is capable of predicting NO and NO2 exptl. profiles. After validating, the model was used for sensitivity studies that revealed the important step in the oxidn.-storage mechanism. [on SciFinder(R)]
