Abstract

The effects of hydrothermal treatment on the performance of Cu, Co, and Mn exchanged MFI zeolite catalysts for the selective reduction of NO with hydrocarbons has been investigated. It is shown that the deterioration of catalyst activity on exposure to steam is due to dealumination of the zeolite framework, causing loss of cation exchange capacity and residual Bronsted acidity, and in the case of Cu resultant aggregation of the transition metal component on the external surface of the zeolite.
