Modeling the transient cyclic operation of a commercial NSR catalyst
چکیده انگلیسی
During cyclic operation starting with a completely regenerated catalyst, model predictions for the NOx concentration profiles are in a good agreement with the experimental data during both the transient and steady cycle-to-cycle regimes. It is also shown that with limited amount of reductant, the regeneration of storage sites takes place only in the front portion of the catalyst up to a certain length and the remaining part of the catalyst is only involved in the storage reactions. After a certain number of cycles, the back of the catalyst reaches its saturation limit for storing NOx and from then on, only the amount of catalyst being regenerated in the front part of the catalyst during the rich phase participates in storage.
