Modelling of Selective Catalytic Reduction of NO_x with NH₃ over the Fe-Cu/ZSM-5 Catalyst

Abstract

The selective catalytic reduction (SCR) of NO x with NH 3 is currently the most effective technology established for the abatement of NO x emissions from stationary sources [1]. In the flue gas, NO x (about 95% NO) react with O 2 and injected NH 3 according to the following equation:Commercial catalysts, in the form of honeycomb monoliths, are composed of an anatase TiO 2 carrier supporting the active components, namely, V 2 O 5 and WO 3 (or MoO 3 ) for the flue gas at a temperature of 300 to 400ºC [2,3].However, due to the biological toxicity of V 2 O 5 to humans and the environment, the narrow operation temperature window (300-400ºC), and the undesired
