摘要：
Dimethyl ether (DME) is an interesting alternative fuel to diesel, but is not an efficient reductant in lean NOx conversion over typical diesel HC-SCR catalysts. Comparatively high deNOx activity was found over H-ZSM-5 in the presence of water, giving reduction of 28% NO and 37% NO2 respectively with a DME/NOx-ratio of 4.
