Zeolite Catalyst With Improved NOx Reduction in SCR

摘要

The present invention is directed to a novel metal-promoted zeolite catalyst, a method of producing the catalyst and a method of sing the catalyst for the selective catalytic reduction of NO_x with improved hydrothermal durability. The novel metal-promoted zeolite is formed from a low sodium zeolite and is hydrothermally treated after metal ion-exchange.
