Title
A novel monolith catalyst of plate-type anodic alumina for the hydrolysis of dimethyl ether
Abstract

A novel monolith catalyst of plate-type anodic alumina was applied in the dimethyl ether (DME) hydrolysis reaction system. The reactivity of the anodic alumina with hydration treatments in DME hydrolysis reaction was investigated. The preferred hydration-treated temperature was found to be 80 °C and the anodic Al2O3/Al monolith exhibited higher activity than the commercial Al2O3 in DME hydrolysis reaction. Meanwhile, the anodic Al2O3/Al monolith was proven to have higher MeOH effluent mole percentage with less unfavorable side reactions than the ZSM-5 catalyst. The anodic γ-Al2O3/Al monolith had just 0.85% coking while the ZSM-5 catalyst had 8.81% after 100 h of continuous experiments.
