Application of the Co-Mg-O catalyst on the selective oxidation of alcohols

Abstract

Oxidation property of the Co-Mg-O (8wt%Co) catalyst is investigated by using the oxidation reaction of methanol, ethanol, 1-propanol, 2-propanol, and 1- butanol as test reactions. The oxidation property of 8Co/MgO catalyst depends u-pon the type of reactant. For the oxidation of methanol and 1-butanol, 8Co/MgO catalyst plays role as a combustion catalyst at all the reaction temperature range. In case of ethanol, 1-propanol, and 2-propanol oxidation reaction, it is found that 8Co/MgO catalyst is an active and selective catalyst. It provides the maximum acetaldehyde and propionaldehyde yield ca. 58% and 53%, respectively, at 400 0C. In addition, it is also shown that the type of support affects the catalytic activity and selectivity of supported cobalt oxide catalyst.
