The interest for synthetic and/or bio-derived jet fuels is increasing with the aim of reducing air transportation dependence on fossil fuels, soot emissions, and carbon footprint. Jet fuels can be produced through Fischer-Tropsch synthesis of paraffins followed by post-processing or blending to meet jet fuel specifications. Synthetic jet fuels mainly contain n-alkanes, iso-alkanes, and cyclo-alkanes, with possible aromatic fractions. The aim of this work is to study the kinetics of oxidation of gas-to-liquid (GtL) and coal-to-liquid (CtL) alternative jet fuels and representative surrogates in a jet-stirred reactor (JSR) operating under the same conditions of temperature, pressure, and equivalence ratio. To experimentally represent the selected synthetic jet fuels, we have designed surrogates consisting of 3-5 representative species. We experimentally studied the oxidation of these representative mixtures (n-decane, iso-octane, and decalin for GtL; n-decane, iso-octane, n-propylcyclohexane, decalin, and n-propylbenzene for CtL), a 100% GtL, and a 100% CtL in a JSR at 10 atm and an equivalence ratio phi = 1. A detailed kinetic reaction mechanism (2430 species versus 10,962 reversible reactions) and model fuels (4-7 components) were developed and validated by comparison with experimental results.
