Experimental and Modeling Study on the Thermal Decomposition of Jet Propellant-10

Jet
Propellant-10 (JP-10) pyrolysis is performed in a continuous
flow tubular reactor near atmospheric pressure in the temperature
range of 930–1080 K, a conversion range of 4–94%, and
two dilution levels of 7 and 10 mol % JP-10 in nitrogen. Identification
and quantification of the pyrolysis products of JP-10 are based on
online two-dimensional gas chromatography with a time-of-flight mass
spectrometer and a flame ionization detector. JP-10 starts to react
at 930 K and is fully converted at 1080 K. Among the more than 70
species up to C14H10 that were identified and
quantified, tricyclo­[5.2.1.02,6]­dec-4-ene was identified
for the first time, indicating the importance of bimolecular H-abstraction
reactions in the consumption of JP-10. Critical assessment of the

that the model predictions of JP-10 agree reasonably well. The newly
acquired and highly detailed experimental data help in understanding
the thermal decomposition chemistry of JP-10 and can be used to validate
future kinetic models of JP-10 pyrolysis.
