Abstract : Studies on combustion of synthetic jet fuels is of growing importance because of their potential for addressing security of supply and air transportation sustainability. The oxidation of a 100% naphthenic cut (NC) that fits with typical chemical composition of biomass or coal liquefaction products, gas-to-liquid fuel (GtL), and a GtL-NC mixture were studied in a jet-stirred reactor under the same conditions (550-1150 K; 10 bar; equivalence ratio of 0.5, 1, and 2; initial fuel concentration of 1000 ppm). Surrogate model-fuels were designed based on fuel composition and chemical properties for simulating the kinetics of oxidation of these fuels. We used model-fuels consisting of mixtures of n-decane, decalin, tetralin, 2-methylheptane, 3-methylheptane, n-propyl cyclohexane, and n-propylbenzene. The proposed detailed chemical kinetic reaction mechanism was validated using the full experimental database obtained for the oxidation of pure GtL, GtL-NC mixture, and pure NC. Kinetic reaction pathway analyses and sensitivity analyses were used for interpreting the results.
