摘要: NOx(尤其是NO)是极难脱除的大气主要污染物之一,研究脱除方法是目前国际上环保化学的一个重要课题.当前普遍采用的是氨选择还原NO.人们发现烃类能有效地对NO进行选择性还原,并具有一定的应用前景,其中Cu/ZSM-5催化剂具有较高的活性.

Abstract: The catalytic selective reduction of nitrogen monooxide by methane on γ-Al2O3and γAl2O3-ZSM-5 supported with Pt and Pd has been investigated.For catalysts supportedon γ-Al2O3 a higher activity and nitrogen selectivity appeared at 350~400℃, for catalystssupported on γ-Al2O3-ZSM-5 they appeared at 400~500℃.The bimetallic catalysts showedabetter catalytic activity than monometallic ones.

Key words: nitrogen monooxide, selective reduction, methane, supported platinum/palladiumcatalyst
