Simulation of single-step dimethyl ether synthesis from syngas

Dimethyl ether (DME) is an alternative energy that simplest ether. DME has 2 ways to synthesis from syngas. The single-step DME synthesis combined methanol synthesis and methanol dehydration in one reactor. This study is focusing on DME production from synthesis gas by used catalyst as CuO–ZnO–Al2O3...

Description
Summary:Dimethyl ether (DME) is an alternative energy that simplest ether. DME has 2 ways to synthesis from syngas. The single-step DME synthesis combined methanol synthesis and methanol dehydration in one reactor. This study is focusing on DME production from synthesis gas by used catalyst as CuO–ZnO–Al2O3/γ-Al2O3. For the simulation we simulated in Aspen Plus V8.8 and used Langmuir–Hinshelwood Hougen–Watson (LHHW) kinetic model for the reaction rate of DME synthesis in a plug flow reactor with catalyst. Simulation is varying the temperature range between 220 °C to 300 °C and pressure between 20 bar to 80 bar to find the suitable condition for the single-step DME synthesis with CuO–ZnO–Al2O3/γ-Al2O3catalyst.
