Title : Dimethyl ether synthesis from syngas over Cu-Zn/Al2O3 catalysts prepared using the Sol-Gel method
Abstract:
Dimethyl ether (DME) is the simplest ether, a neither toxic nor carcinogenic molecule with a boiling point of −25 °C, but it is a liquid at room temperature under a relatively low pressure. DME is a clean fuel alternative to liquified petroleum gas (LPG), diesel engine, power generation in gas turbine plants, propellant of cosmetic products, and used as a chemical intermediate for light olefins and synthetic gasoline production. DME burns without any particulate matter (PM), sulfur-free property and low emission of NOx and CO. DME has a high cetane number and easy to carry and storage of hydrogen and energy. The surface, texture, and structure all perform a major role in intermediate manufacturing. For insight into this, we performed gas chromatography analysis. We have produced DME at various pressures (0.4, 0.9, 1.4, 1.9, 2.4) MPaG using Cu-Zn/Al2O3 catalysts. All three of the solid acids exhibited some degree of deactivation during the reaction, but they were all active and selective in the formation of DME when paired with the copper-based catalyst. The highest production rate of DME was observed when the reaction pressure is 2.4 MPaG.
