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．
The selective catalytic reduction of NO over propylene in the presence of excess oxygen was investigated on a CuCl / ZSM-5 zeolite catalyst prepared by the dispersion method. It was found that this method enabled the active component to be highly dispersed on the support and the prepared high loading CuCl / H-ZSM-5 has higher reactivity at lower reaction temperature than Cu-ZSM-5 prepared by ion exchange method.
