|Title:||Thermal Decomposition Kinetics of the Aviation Turbine Fuel Jet-A|
|Published:||July 02, 2008|
|Abstract:||As part of a larger-scale thermophysical and transport property measurement project, the global decomposition kinetics of the aviation turbine fuel Jet-A was investigated. Decomposition reactions were performed at 375, 400, 425, and 450 °C in stainless steel ampule reactors. At each temperature, the extent of decomposition was determined as a function of time by gas chromatography. These data were used to derive global pseudo-first-order rate constants that approximate the overall decomposition rate of the mixture. Decomposition rate constants ranged from 5.9 10-6 s-1 at 375 °C to 4.4 10-4 s-1 at 450 °C. The kinetic data were used to derive Arrhenius parameters of A = 4.1 1012 s-1 and Ea= 220 kJ•mol-1. In addition to the decomposition kinetics, we have also done a GC-MS analysis of the vapor phase that is produced by the thermal stress applied during the decomposition measurements.|
