Detailed kinetic reaction mechanism for ignition and oxidation of α-methylnaphthalene

A detailed kinetic reaction mechanism capable of describing ignition and oxidation of α-methylnaphthalene has been developed. This mechanism incorporates the removal of the methyl group, the oxidation of naphthalene and benzene, and the formation of PAHs. The kinetic rate data for two-ring species have been approximated by the corresponding one-ring data, since very few direct measurements are available. The model has been validated using species concentrations data obtained by gas chromatographic measurements in a turbulent flow reactor and ignition-delay times from shock tube experiments, both from recent literature. The predicted species concentrations are in reasonable agreement with the experimental data. Also, antoignition delay times are sufficiently well predicted. Applying reaction flux and sensitivity analysis, the main reaction paths are determined.
