摘要：
A wetness method preparation of Co/ZSM-5 catalysts for selective catalytic reduction of NO by propane is shown to be comparable to ion-exchange preparation at the optimum catalytic conversion temperature of 450 degrees C and superior to ion-exchange preparation at lower temperatures. Modification of Co/ZSM-5 catalysts with Ca2+ or Sr2+ significantly improves the catalytic activity.
