A Study on the Kinetic of DME Synthesis from Syngas

In the present study the reaction kinetic and modeling of the reactor for syngas transformation into dimethyl ether using a mixture of a metallic oxides, (CuO, ZnO, Al2O3) and an acidic component (y--Al2O3) as the catalyst has been investigated. A combination of Graff kinetic model for methanol synthesis and Bercic model for methanol dehydration was correlated with the experimental results obtained in this study. The parameter estimation has been done using a set of experimental data. Then, a fixed bed reactor was modeled with estimated parameters. The comparison of results to experimental data confirms the accuracy of model.
