Abstract

A novel catalyst bed packed with two layers of γ-Al₂O ₃ and Na-H-ZSM-5 showed an outstanding CH₃OH dehydration activity, total selectivity to DME and longer stability during the reaction time. The TPD of NH₃ confirmed that appropriate amounts of Na-impregnation on H-ZSM-5 drastically reduced the strong acid-sites resulting in 100% selectivity to DME.
