Abstract
The catalytic activity of ion-exchanged saponites for NO reduction wit h hydrocarbons in the presence of oxygen was investigated. Silver ion- exchanged saponite (Ag-saponite) showed excellent catalytic activity f or NO reduction with propene. The highest activity was obtained for Ag -saponite with a silver loading of 7-8 wt%, on which the addition of w ater vapor to the feed gas promoted NO reduction at temperatures below 400 degrees C. 2-Propanol and acetone served as more efficient reduci ng agents in the presence of water vapor.
