Abstract

Fe/ZSM-5 and Cu-ZSM-5 were investigated for selective catalytic reduction of NO_x with ammonia. The Fe/ZSM-5 catalyst showed over 90% NO conversion from 350 to 500 °C and Cu-ZSM-5 showed over 90% NO conversion from 250 to 350 °C. After pretreatment in 10% H₂O at 700 °C, the Fe/ZSM-5 still exhibited high activities and stability. On the basis of the experiments, Fe/ZSM-5 and Cu-ZSM-5 seem to be promising candidates for diesel-engine NO_x emission control.
