A pilot plant study for selective catalytic reduction of NO by NH3 over mordenite-type zeolite catalysts

Abstract

The copper-ion-exchanged synthetic mordenite and natural zeolite catalysts washcoated on a honeycomb reactor have been examined in a pilot plant for the selective catalytic reduction of NO by NH3. The catalyst life and the cause of the catalyst deactivation were mainly investigated for the design of the commercial reactor to remove NOx from a sintering plant at the steel mill.
