Comparative study of Cu-ZSM-5 and FE-ZSM-5 in the SCR of NOx with i-C4H10
Catalytic activity tests were carried out on Cu-ZSM-5 and Fe-ZSM-5 catalysts for the reduction of NOx with i-C4H10. Formation of CO was the major drawback of Fe-ZSM-5 catalyst, which was attributed to the presence of iron oxide particles. Increasing the Si/Al ratio appeared to slightly strengthen Cu-ZSM-5 catalyst in the presence of water vapor.
