The detailed reaction mechanism (including 67 species and 344 reactions) of the ignition and combustion of a surrogate fuel ( n-decane) for kerosene was reduced by adopting net reaction rate analysis and sensitivity analysis

and a reduced mechanism (including 50 species and 118 reactions) was gained.The ignition delay time of n-decane in the shock tube and the process of n-decane premixed combustion in the premixed burner were simulated by adopting the detailed and reduced reaction mechanisms

and the simulated results was compared with the experimental data.The results show that the ignition delay time

the shape of the profiles of the mole fractions of the reactants and the major combustion products simulated by the detailed mechanism and the reduced mechanism agree well with the experimental data.The n-decane can be a surrogate fuel for kerosene

and the reduced reaction mechanism can describe the kinetic characteristics of the ignition and combustion of n-decane.
