Modelling of the soot oxidation on Fe2O3 catalyst in diesel exhaust
Introduction Diesel particulate filters (DPF) represent a state-of-the-art technology for the removal of soot from diesel exhaust. However, the continuous regeneration of these filter systems remains a considerable challenge, as the trapped soot causes backpressure effects potentially decreasing the engine efficiency 1. While the so-called CRT technique using NO2 is already established for heavy duty vehicles, the catalytic soot oxidation by O2 is considered to be a promising procedure for passenger cars, ships and work machines. Therefore, the present paper aims to provide a fundamental understanding of the oxidation of soot employing an effective Fe2O3 model catalyst 2,3. For this purpose, we report on mechanistic and kinetic investigations as well as on a resulting global-kinetic model implemented into computational fluid dynamics (CFD).
