Article Preview

A series of non-precious metal oxides catalysts were prepared for low-temperature selective catalytic reduction (SCR) of NOx with NH3 in a fixed bed reactor. The catalytic performance was evaluated by the removal efficiency of NOx and N2 selectivity which were respectively detected by flue gas analyzer and flue gas chromatograph. Furthermore, the components of gas products from the above experiments were analysed with 2010 GC-MS. The results illustrated that the MnO2 exhibited the highest NOx conversion to 95.46% and the highest selectivity of N2 to 100% at temperature of 393K, then followed ZrO2, Al2O3 and Fe2O3.
