COMBUSTION OF A GAS-TO-LIQUID-BASED ALTERNATIVE JET FUEL: EXPERIMENTAL AND DETAILED KINETIC MODELING

摘要

The kinetics of oxidation of blends of gas-to-liquid (GtL) jet fuel with 20% vol. of 1-hexanol was studied. New experimental results were obtained using a jet-stirred reactor (p = 10 bar, constant mean residence time of I s, over the temperature range 550-1150 K, and for equivalence ratios of 0.5,1, and 2). Concentration profiles of readouts, stable intermediates, and final products were obtained by probe sampling followed by on-line and off-line gas chro-matography analyses and on-line Fourier transformed infra-red spectrometry. A comparison with corresponding results for Jet A-1 and pure GtL showed these fuels have similar combustion properties. The oxidation of the GtL-hexanol fuel under these conditions was modeled using a detailed.kinetic reaction mechanism consisting of 8217 reactions and 2185 species and a 4-component surrogate fuel mixture (n-decane, iso-octane, n-propyl cyclohexane, and 1-hexanol). The proposed kinetic model showed good agreement with the presently reported jet-stirred reactor concentration profiles.
