✦ Synopsis

The oxidation of ethylene oxide (C2H40) has been investigated in a jet-stirred reactor at high temperature (800-1150 K) in the pressure range 1 to 10 arm for several equivalence ratios (0.5 < ~b < 2). The concentration profiles of 02, H2, CO, CO2, CH4, C2H2, C2H4, C2H6, C3H6, C3H8, CH3HCO, and C2H40 were obtained by probe sampling and gas-chromatographic analysis. Ethylene oxide oxidation in these conditions was modeled using a comprehensive kinetic reaction mechanism. The proposed mechanism is able to reproduce experimental data obtained in our high-pressure, jet-stirred reactor and also ignition delays measured in a shock tube (1070-1330 K, 5-15 atm, 0.36 < ~b < 3.2). The same mechanism has also been validated for the oxidation of CH 4, C2H 2, C2H4, C2H 6, CH3HCO, C3H 6, C3H 8, 1-butene and n-butane, as well as mixtures of CH 4 with C2H6 and/or C3H s under the same conditions.

Normal heptane oxidation in a high-pressure jet-stirred reactor has been investigated experimentally in a wide range of conditions covering the low-and high-temperature oxidation regimes (550-1150 K, l-40 atm, I#J = 1). Reactants, intermediates, and final products have been measured in three differe
