The promoting effect of magnesium oxide on the aluminum oxide activity in the oxidative dehydrogenation of ethylbenzene is observed after initial aluminum hydroxide drying at 120–150⁰C. This effect considerably weakens after the aluminum hydroxide heat treatment at 550⁰C what may apparently be bound up with the influence of heat treatment on the value of specific surface area, the hydroxyl cover condition and other properties of aluminum oxide

Keywords : ethyl benzene, styrene, aluminum oxide, promoting, magnesium, calcium oxides
