One-dimensional heterogeneous and pseudohomogeneous plug flow models were employed to model an adiabatic fixed bed reactor for the catalytic dehydration of methanol to dimethyl ether. Longitudinal temperature and methanol conversion profiles predicted by these models were compared to those experimentally measured in a pilot reactor. The reactor was packed with 3-mm [gamma]-Al[sub 2]O[sub 3] pellets and operated in a temperature range of 290--360 C and at a pressure of 2.1 bar. Intraparticle mass transport was found to be the rate-controlling step.
