The selective catalytic reduction of nitrogen monooxide with propene in the presence of oxygen has been studied over CuCl/ZSM 5 prepared by the disperse method. It was found that the catalytic properties were changed obviously with the change of the type of parent zeolite, and the conversion of NO on CuCl/H ZSM 5 was much higher than that on Cu/Na ZSM 5. For CuCl/H ZSM 5, the activity was increased with the increasing of copper amount. The activity of CuCl/H ZSM 5(Cu amount4%) was higher than that of ion exchanged Cu ZSM 5 zeolites at 573K.
