Selective catalytic reduction of NO by ammonia over Fe-ZSM-5 catalysts

Abstract

In the selective catalytic reduction (SCR) of NO by ammonia, over-exchanged Fe-ZSM-5 prepared by sublimation of FeCl3 into H-ZSM-5, shows superior catalytic activity and stability in a wide temperature range; its activity is promoted by the presence of water in the feed while SO2 is a weak poison at low but a promoter at high temperatures; its remarkable durability towards H2O and SO2 makes this zeolite catalyst a potential choice in Denox applications for stationary sources and heavy Diesel engines with ammonia or urea reductants.
