Development of Catalyst for Industrial Flue Gas Denitration at Low Temperature

Abstract:

The most effective technology currently for flue gas denitrition is selective catalytic reduction (SCR). And the major problem against spreading SCR technology is the high cost and low efficiency of the catalyst for SCR. Al₂O₃ supported Mn-Fe oxide precursor was prepared through water/ethanol coprecipitation and then nitridized through NH₃-TPD. Thus the inexpensive and efficient Mn-Fe-O-N/Al₂O₃ catalyst was obtained. The catalyst with a Mn/Al molar ratio of 0.4 and a Fe loading of 6.0 wt.% was testified to have the best performance for denitrition. The NO_x conversion reached 95% at low temperature (150~200°C).
