| Abstract: | 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% NO2 respectively with a DME/NO x -ratio of 4. |
