The formation of DME from methanol requires a catalyst with optimum acid properties. Usually, strong acid sites favor secondary reactions that lead to undesired hydrocarbons and coke formation, which eventually causes catalyst deactivation [5]. A myriad of solid acid catalysts has been explored for the conversion of methanol into DME, including γ-Al2O3, modified alumina with silica, TiO2–ZrO2, and zeolite and zeotype materials (HZSM-5, HY, AlPO4, SAPOs, etc.) [6]. Zeolite materials tend to deactivate rapidly because their strong acid sites are responsible for the formation of significant amounts of undesired by-products (hydrocarbons and carbon deposits) [7]. On the other hand, γ-Al2O3, which possesses strong Lewis acid sites, exhibits lower methanol dehydration rates compared to zeolites, and thus, could be due to the preferential adsorption of generating H2O molecules on the Lewis acid sites under the reaction conditions [5]. It is important to develop new catalysts to replace the acids commonly used in this reaction and to overcome the problems take place by using other solid acid catalysts.
