Abstract

Abstract

A series of M/REY(M=Cu, Mn, Fe, Ce) catalysts were prepared by impregnation method. The catalysts were characterized by XRD, NH₃-TPD, NO-TPD and H₂-TPR, and XPS. The catalytic activity of the catalysts was evaluated in the fixed-bed reactor for the selective catalytic reduction of NO with NH₃ in the presence of SO₂. The results show that the performance of catalysts was affected by the type and load of active component. The Cu(3)/REY catalyst exhibited good activity at low temperature in presence of SO₂. The NO conversion is over 95% at the temperature range of 254~390℃. The catalytic activity of Cu(3)/REY catalyst is related with its excellent redox properties and the performance of NO adsorption-desorption.
