Fuels Combustion Research, Supercritical Fuel Pyrolysis
Abstract
Concentrating on the problem of fuel line fouling possible in the next generation aircraft gas turbines, extensive experimentation on the pyrolysis of the endothermic fuels, methylcyclohexane, decalin and tetraline under sub and supercritical was completed. Results revealed that the fuel decomposition rates had an activation energy essentially the same for all fuels and cases, but that the pre-exponential factor was two orders of magnitude higher under supercritical conditions. Although the pyrolysis products were generally the same, higher order cyclic hydrocarbons were found under supercritical conditions. These compounds were also found to have lead to known precursors for particulate formation and to have increased with increasing pressure. These differences between sub and supercritical conditions have been postulated to be due to the phenomenon known as caging at high pressures.
