The diesel dual fuel engine emits CH₄ in the exhaust gas. This makes the exhaust gas more difficult to treat comparing to the exhaust gas from the conventional engine since CH₄ requires high exhaust temperature to oxidize. In addition, another parameter such as exhaust flow rate, specie concentrations, especially CO, C₃H₈, and H₂O have tremendous impact on Diesel Oxidation Catalyst performance on reducing CH₄.

This research is aimed to propose a kinetic model based on Langmuir Hinshelwood mechanisms that includes several terms such as CH₄, C₃H₈, CO, O₂, and H₂O concentrations in order to gain a better understanding on the catalytic reaction and to provide a simulation with an accurate prediction. The model’s kinetic parameters are determined from the experiment by using synthetic gas. The composition of synthetic gas is simulated to be similar to the real exhaust gas from diesel dual fuel engines. By comparing the simulation to the experiment, this kinetic model can give accurate results with the kinetic model that can be used to predict the conversion rate of the exhaust gas in diesel oxidation catalyst.
