摘要：
Dimethyl ether (DME) is an interesting alternative fuel to diesel, but is not an efficient reductant in lean NO (x) conversion over typical diesel HC-SCR catalysts. Comparatively high deNO(x) activity was found over H-ZSM-5 in the presence of water, giving reduction of 28% NO and 37% NO(2) respectively with a DME/NO(x)-ratio of 4.
