The paper gives results of a fundamental study of low-temperature deep (complete) oxidation of n-hexane, benzene, and ethyl-acetate over a 0.1% Pt, 3% Ni/gamma-AL203 catalyst. (NOTE: Deep catalytic combustion of volatile organic compounds--VOCs--is emerging as an important emission control technique.) These VOCs were subjected to oxidation as single components and as binary and ternary mixtures at temperatures of 160-360 C. n-Hexane oxidation was significantly inhibited in the mixtures, and ethyl acetate oxidation was significantly enhanced in the mixtures. An approach based on the Mars/van Krevlan rate model is being used to explain these inhibitions and enhancements. The model was reasonable successful in predicting the conversion of benzene and n-hexane in their binary mixture, in the intrinsic kinetic region. However, as expected, it overpredicted the conversions in the mass transfer region, since the effect of mass transfer was not incorporated.
