A kinetic model of ignition and combustion of heavy n-alkenes n-C₁₀H ₂₂ and n-C₁₂H₂₆), benzene, and jet propellant Jet-A, hich is modeled by a BD surrogate consisting of n -decane 80%) and benzene (20%), is developed. The model is tested through comparisons with a large set of experimental data on the ignition delay time in both higher-temperature ( T > 1000 K) and low-temperature ( T = 650–950 K) regions and also on the behavior of species concentrations during benzene oxidation in a flow-type reactor and during benzene combustion in a special burner. Other reaction mechanisms developed for the description of combustion of various surrogates modeling kerosene are briefly analyzed. It is demonstrated that the proposed model ensures a more adequate description of the measured ignition delay times than other known kinetic models, especially in the low-temperature range ( T = 650–950 K). Specific features of the kinetics of low-temperature oxidation of the BD surrogate are analyzed.
