Název v původním jazyce

Transient behaviour of catalytic monolith with non-uniform distribution of NOx storage capacity

Popis výsledku v původním jazyce

Periodically operated NOx storage and reduction converters represent a technology that is able to eliminate the emissions of nitrogen oxides from lean-burn engines (e.g., diesel). Laboratory experiments on transient behaviour of an NOx storage catalyst have been performed. Dependence of the NOx storage capacity on the position in the monolith has been studied. Large series of experiments have been performed with the catalyst samples, focused on the temperature dependence of the NOx and oxygen storage capacities, the light-off temperatures of CO, H2 and C3H6 oxidation, NO/NO2 transformation, water gas shift, steam reforming, and NO reduction, including the effects of the reductants (CO, H2 and C3H6) concentration and duration of the enrichment phase. Aheterogeneous, spatially distributed mathematical model of the converter has been developed and the reaction-kinetic parameters have been evaluated from the experiments.
