Abstract

Selective catalytic reduction (SCR) is emerging as the most promising technology for the abatement of NO_x emissions from diesel vehicles. Given the high NO_x conversion efficiency requirements and the need for shorter development cycles and cost reduction, the use of numerical simulation is nowadays well established. In this work, the fundamentals of flow-through and wall-flow SCR converters are presented. The model parameter calibration, the development of SCR kinetic models from small-scale reactors, and their applicability to real-world full-scale applications are discussed. Since modern exhaust systems usually consist of more than one aftertreatment device, the last part is dedicated to the modeling of combined SCR-DPF systems, either in-series or as a multilayered catalyst.
