Sulfonic acids grafted on inorganic support such as SiO2 and MCM41 was used as catalysts for conversion of methanol to dimethyl ether. In this experimental work the catalysts were compared for their catalytic properties in a continuous flow fixed-bed reactor at temperatures between 180 and 320 °C and 1 bar. It was found that all SO3H-functionalized materials in this study were active, selective and stable for DME synthesis. According to the experimental results MCM-41-(CH2)3-SO3H exhibited the best performance, related to its higher surface area and acidity. © 2019 Elsevier Ltd
