Abstract

In the present study a kinetic model for the catalytic dehydration of methanol to dimethyl ether, using some baria-modified gamma alumina as the reaction catalyst have been presented. Three catalyst samples were prepared consisting of Ba2+ impregnated on γ-Al2O3, using barium nitrate solution. It was noted that the Ba2+ content of the catalysts had a high impact on the activity of the latter. The operating temperature range was 260-290oC and the pressure was 1 bar. Catalysts' activity and kinetic measurements were carried out using a catalytic fixed bed micro- reactor.
