摘要: 研究了由分散法制备的CuCl/ZSM-5分子筛催化剂上丙烯在过量氧存在下选择催化还原NO反应,发现该法能使活性组份高度分散于载体上,且所制备的高负载量CuCl/H-ZSM-5与离子交换法制备的Cu-ZSM-5相比在较低反应温度下具有更高的反应活性.

Abstract: 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 amount>4%) was higher than that of ion-exchanged Cu-ZSM-5 zeolites at 573K.

Key words: CuCl/ZSM-5 zeolite, Nitrogen monooxide, Selective catalytic reduction
