Selective Catalytic Reduction of NO with C3H6 on CuCl/MCM-41 Prepared by Disperse Method

Abstract

Abstract: The selective catalytic reduction (SCR) of NOwith propene over CuCl/AlMCM-41 and CuCl/ AlMCM-41 catalysts prepared by dispersion method was studied.It was found that CuCl/AlMCM-41 exhibits a substantially higher catalytic activity over CuCl/SiMCM-41.And the function of copper species in these catalysts was also investigated by means of H₂-TPR, IRand ESR.The results show that the copper ions (Cu²⁺and Cu⁺ ) coordinated with framework aluminium are a main active centre for SCRof NOover CuCl/AlMCM-41 catalyst, whereas in CuCl/SiMCM41 catalyst these kinds of copper ions could not been found.

Key words: CuCl/MCM- 41, NO, Selective catalytic reduction
