In this study kinetic parameters were fitted to measurement data taken from an engine test rig  by using a dynamic catalyst monolith model. Analysis of mass and heat transfer parameter sensitivities together with model based design of experiments were applied to facilitate faster re-fitting of kinetic parameters to new catalysts.
