摘要：
The effect of co existing organics on the selective reduction of NO using ammonia as a reducing agent was investigated over Cu/ZSM-5 catalysts Addition of organics in the feed gas resulted in deactivation of the catalysts NH3-SCR activity at 200 degrees C decreased in the following order acetaldehyde>n decane>methyl decanoate, p-xylene>m-xylene After oxidation of the deactivated catalysts in an oxygen flow at 500 C, the activity of the catalyst was recovered Hence, the cause of the deactivation was considered to be a carbonaceous material deposited over the catalyst
