Abstract:

The paper presents a simulation studies of nitrogen oxide catalytic reduction. Analysis shows the effect of temperature on emission of NOx & CO & C3H6. Monolithic three-way catalysts are applied to reduce the emission of combustion engines. The design of such a catalytic converter is a complex process involving the optimization of different physical and chemical parameters. Numerical simulation can be used as an effective tool for the investigation of the catalytic properties of a catalytic converter and for the prediction of the performance of the catalyst. To attain this goal, a two-dimensional flow field description is coupled with a detailed surface reaction model. This surface reaction mechanism (with C3H6 taken as representative of unburnt hydrocarbons) was developed using sub-mechanisms recently developed for hydrogen, carbon monoxide and methane oxidation, literature values for C3H6 oxidation, and estimates for the remaining unknown reactions. The analysis is CFD analysis with validation of experimental analysis of reference paper [10]. Given Analysis is based on Change of Proportion of Precious Metal (Pt/Rh) and observed its effect on emission of pollutant with respect to temperature.
