Investigation of combined DOC and NSRC diesel car exhaust catalysts

Popis výsledku v původním jazyce

The system of two monolithic catalytic reactors - diesel oxidation catalyst (DOC) and NOx storage and reduction catalyst (NSRC) - is studied. The catalysts are used in series for the conversion of exhaust gases from automobiles with Diesel engines (or other lean-burn engines). Several tens of catalytic reactions are considered in the description by a model based on a system of non-linear partial differential equations (mass and enthalpy ballances). A simulation study is performed to examine the effectsof parameters determining the performance of the upstream-located DOC (size and effective heat capacity of the monolith, catalytic activity in individual reaction steps) on the performance of the NSRC in the European driving cycle (NEDC). Effective numerical methods used for the solution of the resulting non-linear PDEs are described. Results of the maximization of the overall NOx conversion over the NEDC for several DOC and NSRC reactor configurations and different regeneration strategi
