Summary:

A one-dimensional two-phase model of an adsorptive catalytic monolith reactor (used as Lean NOx Trap, LNT) is developed and analyzed. The model simulates the features of NOx storage and reduction (NSR), a periodic process involving the sequential trapping on a storage component and conversion of NOx to nitrogen under lean conditions found in the exhaust of lean burn and diesel vehicles. The effect of design and operating parameters, such as the lean and rich times and feed temperature, on NO2 conversion is examined. Using a relatively simple kinetic model and without any attempt to fit data, the LNT model predicts the dependencies of NO2 conversion on several feed parameters that are in good agreement with experimental observations
