Abstract

This study focused on the effect of alumina properties on the catalytic performance in the dehydration of methanol to synthesize dimethyl ether. The catalysts (γ-Al2O3 and η-Al2O 3) were prepared from boehmite and bayerite, respectively, via calcination at various temperatures. With heat treatment, the properties of alumina have been changed significantly. Under identical reaction conditions, γ-Al2O3 calcined at 500 °C and η-Al 2O3 calcined at 600 °C showed the highest catalytic activity, because of high acid site density among the same types of alumina. Interestingly, η-Al2O3 showed higher catalytic activity than η-Al2O3, although both catalysts possess comparable acidic properties. This means the structure type of alumina is crucial to determine catalytic performance in this reaction.
