General study of catalytic oxidation of various VOCs over La0.8Sr0.2MnO3+x perovskite catalyst -: influence of mixture

The catalytic oxidation of volatile organic compounds (VOCs) with different functional groups: propane, propene, hexane, cyclohexane, methylcyclohexane, benzene, toluene, ethanol, propan-2-ol, propanal, acetone, ethyl acetate, isopropyl acetate, MEK are studied, individually or in two-component mixtures over La0.8Sr0.2MnO3+x perovskite in air. Total conversion to CO2 and H2O occurs at temperature below 623 K. However, some by-products are detected in the flue gas, especially during the oxy-derivative compounds oxidation. For the mixtures, the comportment of the VOCs is modified. A mixture effect is observed depending on the composition of the mixture. (C) 2002 Elsevier Science B.V. All rights reserved.
