Abstract
Global kinetic model for a Pt-Pd diesel oxidation catalyst (DOC) is proposed and validated. Experimental data was obtained using different concentrations of the artificial gas mixtures which were passed over a bimetallic catalyst. Previous works of Voltz [1], Pandya [2], Sola [3] and many others were used to propose a new model, which was validated using a MATLAB based solver and optimizer. A reasonable match between the experimental data and predicted values was seen for all experimental conditions except for the runs with CO, H2, C3H6 and NO. Some fundamental observations were made in this case but further investigations are necessary to improve the model.
