摘　　要：NOx和SO2是环境污染的主要污染源,但国内外对NOx的治理还比较落后,仍然没有找到技术上合理、经济上可行的治理方案。NO是NOx的主要成分。随着人们对环保的重视和对环境质量要求的提高,NO的治理也愈来愈受到重视。研究了以Al2O3为载体,Cu做活性组分用烃类气体(C3H6)选择性地催化还原NO。通过NO的转化率说明了在各种条件下催化剂的活性。并且利用了SEM、XRD等先进的表征手段对Cu/Al2O3催化剂的作用效果进一步作了分析和论证。说明了在Cu/Al2O3催化剂上用烃类气体选择性催化还原NO是可行的。At present, NOx and SO2 are the primary resource in environmental pollution. SO2＇ s control and treat techniques have been matured in all over the world, but the treatment of NOx is still behindhand. NO is NOx. the primary ingredient. With the development of the society, people pay more attention to environment protect and its quality and treat NO. Being as carrier and active component, respectively Al2O3 and Cu were used to selectively catalyze the reduction of NO in this paper. The catalyst was characterized by SEM and XRD. This research indicated that it was feasible to use hydrocarbon to selective catalytic reduction NO.
