When hydrocarbon aviation fuel is heated above its critical point inside a regenerative cooling channel,
the fuel is decomposed into hydrogen and various low molecular-weight hydrocarbons, which affects
the performance of active regenerative cooling systems. Therefore, this study investigates the pyrolysis
of exo-THDCPD (C10H16, exo-tetrahydrodicyclopentadiene), the major component of JP-10 aviation fuel
experimentally. In order to understand the thermal decomposition characteristics of exo-THDCPD within
a regenerative cooling channel, a batch reactor with a fluidized sand bath heater was used to expose
the fuel under supercritical conditions (4 MPa, 540-630 K) to have the conversion rate of 3-76%. The
constituents of the pyrolysis products were identified by GC-MS, GC-FID and GC-TCD systems, which
have revealed that hydrogen, methane, ethylene, ethane, propylene, propane, and butane are found
to be the major gaseous products. In the liquid products, on the other hand, cyclopentane,
cyclopentene, cyclopentadiene, cycloheptadiene, benzene, and toluene are dominant. Furthermore, a
brief analysis on the thermal decomposition mechanism was carried out based on the experimentally
obtained data.
