摘要：Dimethyl ether (DME) as a new fuel has attracted many attentions for a number of decades and its commercial production has become a vital subject in fuel and energy productions. It can be technically produced in an adiabatic fixed-bed reactor by methanol dehydration by means of solid acidic catalysts such as γ_Al2O3. Methanol conversion and DME yield can be affected by the process settings such as feed temperature and flow rate. In order to examine the influences of these parameters on methanol conversion, a one-dimensional pseudo-homogenous model was developed. The optimum feed condition, with these factors affecting the process in an interacting manner, is determined while imposing some constraints on each decision variable. The performance of the reactor simulated using this procedure indicated a good agreement with its experimental data. This procedure can be applied to any other adiabatic fixed-bed reactor.
