The kinetics of oxidation of n-tetradecane was studied experimentally in a jet-stirred reactor (JSR) at high pressure (10 atm), at temperatures ranging from 560 to 1030 K, at a constant residence time () of 1 s, and for three equivalence ratios (phi = 0.5, 1.0, and 2.0). Chemical analyses by Fourier transform infrared spectrometry and gas chromatography yielded mole fractions of reactants, stable intermediates, and final products as a function of temperature. A kinetic reaction mechanism based on previous studies from this laboratory was developed and validated by comparison with the present experimental results. The proposed reaction mechanism consisted of 7,885 reversible reactions involving 1,813 species. Experimental data and simulation results obtained in the current work were found in good agreement. Ignition delays of n-tetradecane/air mixtures were also simulated.
