Kinetics of Oxidation of a Reformulated Jet Fuel (1-Hexanol/Jet A-1) in a Jet-Stirred Reactor: Experimental and Modeling Study

Abstract

The kinetics of oxidation of a reformulated jet fuel (commercial jet A-1/1-hexanol 90/10% in vol.) were performed using a fused-silica jet-stirred reactor over a range of experimental conditions (temperature: 560–1030 K, pressure: 10 atm, mean residence time: 1 s, equivalence ratio: 0.5 to 2, initial fuel concentration: 1000 ppm). Concentration profiles of reactants, stable intermediates, and final products were measured as a function of temperature. A chemical kinetic reaction mechanism consisting of 7011 reactions involving 2176 species was proposed to represent the data. It is based on previously proposed chemical schemes for the oxidation of 1-hexanol, n-decane, gasoline, and several jet fuels under similar conditions. The kinetic modeling showed reasonable agreement with the present data over the entire range of conditions considered in this study. Reaction paths analyses and sensitivity analyses were used to rationalize the results. Supplemental materials are available for this article.
