Simulation of a Diesel Oxidation Catalyst Used in a NOx Storage and Reduction system for Heavy Duty Trucks

Abstract
This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account.



Experimental data has been determined on a monolithic oxidation catalyst mounted after a heavy duty diesel engine in a rig. The conversion of hydrocarbons is predicted fairly well. The temperature increase determined experimentally cannot be simulated. This leads us to believe that there must be an extra highly exothermic reaction taking place. This could be the combustion of the volatile part of diesel soot.
