OXIDATION OF 1-METHYLNAPHTHALENE AT 1–13 ATM: EXPERIMENTAL STUDY IN A JSR AND DETAILED CHEMICAL KINETIC MODELING

International audienceThe kinetics of oxidation of 1-methylnaphthalene have been studied in a jet stirred reactor (800 ≤ T/K ≤ 1421, 1 ≤ P/atm ≤ 10, 0.5 ≤ equivalence ratio ≤ 1.5). Molecular species concentration profiles of reactants, stable intermediates and final products were measured by sonic probe sampling followed by on-line GC-MS analyses and off-line GC-TCD-FID and GC-MS analyses. The oxidation of 1-methylnaphthalene was modeled using a detailed chemical kinetic reaction mechanism (146 species and 1041 reactions, most of them reversible). The proposed kinetic scheme was also validated simulating ignition delay times of 1-methylnaphthalene/air mixtures taken from the literature. Sensitivity analyses were performed and reaction path analyses, based on rates of reaction, were used to interpret the results
