Abstract

For a catalytic NOx reduction process for natural gas-fueled lean-burning engines; selective catalytic reduction of NOx by propane was studied on metal ion-exchanged zeolite catalysts. A comparative study on Cu-and Co-ZSM-5 showed the superiority of Go-bared catalysts for C3H8-SCR in the presence of water vapor. Investigation into various Go-zeolite catalysts showed that Go-Beta has superior activity and selectivityfor NOx reduction. Durability tests of the catalyst in a model gas simulating gas engine exhaust showed that the activity of Go-Beta is sufficient even in the presence of SOx after 5000 h of operation, whereasCo-Mordenite and Co-ZSM-5 lost their activity in several hundred hours of operation, (C) 1997 Elsevier Science B.V.
