Low Temperature Oxidation Chemistry of JP-8 and its Surrogates at High Pressure

摘要

A research program to study the low temperature oxidation chemistry of JP-8 at high pressures has been conducted at Drexel University. The current program was initiated in June 2003 through a grant from the Army Research Office (Grant No. DAAD19-03-1-0070, Project No. 44458-EG) and was completed in July 2006. The objectives of this project were to determine the effects of fuel composition variations in JP-8 reactivity at low and intermediate temperatures (600 - 1000 K) and elevated pressures (2 - 20 atm), to develop a chemical surrogate for JP-8, and to obtain kinetic information of the JP-8 surrogate components neat and in blends. Fuels were oxidized in a pressurized flow reactor, with complimentary experiments conducted in a single cylinder research engine. Detailed kinetic information was obtained utilizing gas chromatography with flame ionization detection and coupling to a mass spectrometer. In addition, hydrocarbons similar to the JP-8 surrogate components but of lighter molecular weight were studied in detail to ascertain the fundamental branching pathways of hydrocarbons at low temperatures; several other potential surrogate components and blends, including for Fischer-Tropsch JP-8, were also examined.
