- W1526493043 abstract "Ethanol was found to react with ozone at lower temperatures than with oxygen and also with lower activation energy. This is in agreement with the stronger oxidizing ability of ozone compared to oxygen. In situ laser Raman spectroscopic studies showed the existence of adsorbed ethoxide species on the catalyst surface under reaction conditions; however, at a much lower concentration than when oxygen alone was used as the oxidant. Ozone was generally found to be effective at enhancing the conversion of VOCs, especially at low temperatures. The kinetics of complete oxidation of benzene by ozone on MnO2 was investigated. It was concluded that the rate determining step for benzene oxidation by ozone was ozone decomposition. The oxidation of lower aliphatic alcohols by ozone over silica and alumina has been studied. It was also found that the main products of the oxidation reactions were acetaldehyde and carbon dioxide from ethanol, propionaldehyde and carbon dioxide from n-propanol, and acetone from isopropanol. Alumina and silica supported MnO2 catalysts were prepared by incipient wetness impregnation of supports, using manganese acetate, as the precursor and were calcined in air at 773 K for 3 h prior to use. The crystal phases of MnO2 in the catalysts were identified, using X-ray diffraction (XRD), and their surface areas were determined by N2 physisorption, using the Brunauer, Emmett, and Teller (BET) method." @default.
