通过使用少量丙烷作为氧化铝、二氧化硅-氧化铝、二氧化钛和氧化锆催化剂上的还原剂，在富氧气氛中将氮氧化物高度选择性还原成二氮。从一系列硅铝催化剂的活性和氨TPD测定数据来看，酸性是决定催化剂活性的主要因素之一。
Highly selective reduction of nitrogen oxides to dinitrogen occurs to a high level in oxygen-rich atmospheres by using a small amount of propane as a reducing agent over alumina, silica-alumina, titania and zirconia catalyst. Judging from the data of activity and ammonia TPD measurement on a series of silica-alumina catalysts, acidity is suggested to be one of the main factors that determine catalytic activity.
