| Using data from artificial gas mixtures, global kinetic models for a platinum diesel oxidation catalyst are developed. The modelling of CO and C3H6 was inspired by the classical work of Voltz et al., while the modelling of NO and C3H6 was based on the earlier work of Pandya, Mulla et al., Bhatia et al. and Hauff et al. The creation of the model was performed piecewise, starting from experiments on single reactants. A new model is proposed to account for the formation of N2O. A global model is developed that is able to correlate with reasonable accuracy the results from the complete gas mixture. The model is not, however, able to correlate all of the data from feeds containing the complete set of reactants and those with single or dual reactants present. |
