Abstract
Autoignition characteristics of an alternative (non-petroleum) and two conventional jet fuels are investigated and compared using a heated rapid compression machine. The alternative jet fuel studied is known as “S-8”, which is produced by Syntroleum via the Fischer-Tropsch process from synthesis gas derived from natural gas. Specifically, ignition delay times for Jet-Fuel/oxidizer mixtures are measured at compressed charge pressures corresponding to 7, 15, and 30 bar, in the low-to intermediate temperature region ranging from 615 to 1100 K, and for equivalence ratios varying from 0.42 to 1.57. Further, the dependence of both the first-stage and the overall ignition delays on parameters such as pressure, temperature, and mixture composition is reported. A comparison between the autoignition responses obtained using S-8 and two petroleum-derived jet fuels, Jet-A and JP8, is also conducted, to establish an understanding of the relative reactivity of the three jet fuels. It is found that under the same operating conditions, while the three jet fuels share the common features of two-stage ignition and a NTC type trend for ignition delay over a similar temperature range, S-8 has the shortest ignition delay times, followed by Jet-A and JP-8.
