摘要：AgNaZSM-5 catalysts were studied for the SCR of NO by methane in excess of oxygen. The conversion rate of NO to N2 had a linear dependence on the Ag loading (4.32~13.64%), indicating that all Ag species in the zeolite were active for the CH4-SCR reaction. The presence of excessive oxygen in the feed gas favored the CH4-SCR reaction. Surface nitrates were formed on silver catalyst and could be effectively reduced by methane based on the temperature programmed desorption profiles in He and 2%CH4/He after the co-adsorption of NO and O2. This is an abstract of a paper presented at the 13th International Zeolite Conference (Montpellier, France 7/8-13/2001).
