Catalytic combustion of volatile organic compounds in binary mixtures over MnOx/Al2O3 catalyst

摘要: Abstract In this work the catalytic performance of an alumina supported manganese oxide catalyst in ethanol, ethyl acetate, toluene and mixtures them was studied. The reactivity each VOC investigated increased following order: ethanol > ethyl acetate > toluene. Toluene affects acetaldehyde yields, favoring partial combustion ethanol acetate. There is a competition for adsorption sites between acetate because both are polar molecules. Mixture effect decreases when conversion temperature range component mixture different, as case ethanol–toluene acetate–toluene mixture, consequently, total determined by at which most difficult molecule oxidized, toluene.
