Some issues in the gas-phase dehydration of methanol to dimethyl ether
Thread Content
Does anyone here know the general process conditions for producing dimethyl ether via the gas-phase dehydration of methanol in industry? I would also like to ask: when conducting kinetic experiments in the laboratory using γ-Al2O3 as a catalyst, how should the various experimental parameters (such as temperature, pressure, and flow rate) be set? The boss has just assigned new experiments, with a tight deadline. Please, everyone, help out as much as you can.
Either gamma-alumina or acidic molecular sieves can be used; the reaction pressure is 0.6–0.8 MPa, and the temperature ranges from 240 to 300 degrees Celsius.
Operating pressure: 0.8 MPa, operating temperature: 280 degrees
It seems that the main building uses Tianyi’s technology, just like our company does. Operating pressure: 0.6–0.8 MPa, temperature: 240–280℃
More or less, but the starting temperature used in our laboratory is around 260°C; however, the actual experiments are carried out at approximately 340°C. I’m not sure if this approach is suitable for industrial applications
