Scr Of Nox

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 N2selectivity 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 MnO2exhibited the highest NOx conversion to 95.46% and the highest selectivity of N2to 100% at temperature of 393K, then followed ZrO2, Al2O3and Fe2O3.

Low-temperature SCR denitration in new style PC kiln was conducted using TiO2 catalyst. First, the theoretical quantity of ammonia consumption was calculated and applied in this experiment. Maintain the volume of exhaust gas flow and ammonia consumption quantity, concentration of NOx reduced from initial 503 mg/Nm3 of 120°C to 57.5 mg/Nm3 of 170 °C after catalytic reaction. When excess ammonia was injected into SCR reactor, efficiency of the denigration increased linearly too with temperature increasing and achieving the maximum of 89.45% under conditions of 170 °C, ammonia flow rate of 4.00 SL/min. After 20h continuous operating, efficiency of the denigration fluctuated ± 1% only. Pore of TiO2 catalyst have not blocked by exhaust smoke, that is to say: Low-temperature SCR TiO2 catalyst can be long-term used in new style PC kiln.
