An SCR using bimetallic Fe-Cu-ZSM-5 catalyst is studied. The effects of major flow parameters such as compositions of the catalyst, temperature, the gaseous flow rate at the inlet and the thickness of the catalyst on performance of the SCR at low temperature is studied. The chemical kinetics models are taken from the literature to model the chemical reactions in the device. Now, the catalysts with different compositions are modelled as if they are different monometallic catalyst, each with a calibrated set of chemical kinetics parameters. Due to special filters in the converters we use, we assume that the chemical reactions in the simulation are volumetric reactions.
