Characteristics of catalytic filter for SCR of NO by NH3 at low temperature

摘要

NOX contributes to the formation of acid rain, ground level and deterioration of water quality. Many research studies addressing removal of NOX have focused on developing a catalyst system. This study is to examine the effect of catalyst(CuxMnyOz) loading at low temperature(150~250 ??) using SCR(Selective Catalytic Reduction) to remove NOX by NH3. The experimental conditions are NO/NH3 mole ratio 1, flow rate of 1.0 m/min and catalyst loading of 250-500 g/m 2 . As a result, NO reduction increases as catalyst loading increases.
