An important step in the initial oxidation of hydrocarbons is the abstraction of H by hydroperoxyl radical (H02). In this study, reaction rate constants are derived for H abstraction by H02 from the weakest H bond in methanol, ethenol, acetaldehyde, toluene and phenol. Rate constants are provided in the simple Arrhenius form. Reasonable agreement was obtained with the limited literature data available for acetaldehyde and toluene. For the case of phenol, direct abstraction of the hydroxyl H was found to dominate over H02 addition to the ring. The results presented herein should be useful in modelling the lower temperature oxidation of the five compounds considered.

Rate constants for hydrogen abstraction reactions by the hydroperoxyl radical from methanol, ethenol, acetaldehyde, toluene and phenol

Pressurized oxy-fuel combustion is regarded as a new generation of oxy-fuel technology. The ignition delay times of methane in an O2/N2 atmosphere (0.21O2 + 0.79N2) and an O2/CO2 atmosphere (0.21O2 + 0.79CO2) were measured in a shock tube at a pressure of 0.8 atm, an equivalence ratio of 0.5, and within a temperature range of 1501–1847 K. The present experimental data and the experimental data of Hargis and Peterson at 1.75 and 10 atm were adopted to evaluate five representative chemical kinetic models. This paper studied the chemical effects (chaperon effects of CO2 and the effects of reactions containing CO2) and physical effects of CO2 on the ignition of methane at different pressures and temperatures in detail using a modified model. Artificial materials X and Y were employed to analyze the chemical and physical effects. The analysis showed that the physical effects of CO2 inhibit the ignition of methane and are not sensitive to the temperature. The chemical effects of CO2 vary greatly with the pressu...
