LTA catalyst with extraframework iron and / or manganese for exhaust gas treatment

机译:具有骨架铁和/或锰的LTA催化剂用于废气处理

摘要

Provided is a catalyst composition comprising a zeolite having an LTA structure with iron, manganese, or a combination thereof as an extraframework metal. The zeolite has a silica to alumina molar ratio (SAR) of 15 to 70 and may contain 0.5 to 10 weight percent iron, manganese, or combinations thereof, based on the total weight of the zeolite. Also provided are a catalyst article that includes a catalyst composition and a substrate, a system for treating exhaust gas that includes the catalyst article, and a method of treating exhaust gas. The catalyst composition provides improved catalytic performance in the selective catalytic reduction of NOx. [Selection diagram] None
