Abstract : The general effort in understanding the oxidation of aromatic components of JP fuels led to the completion of a study of the oxidation of 1-methylnaphthalene, a species known to contribute to soot formation. The results were the first to report detailed oxidation kinetics for any PAH despite the presence of PAH's in many practical fuels. Results have also been reported on the understanding of aliphatic fuel pyrolysis and oxidation on methyl- cyclohexane (MCH). an endothermic fuel, and its blend with toluene. Sooting diffusion flame experiments have led to the conclusion that under combustion conditions a critical temperature for soot partide nucleation exists irrespective of the fuel species. This study explained why a smoke height occurs. New degradation studies of 'liquid' toluene, MCH and toluene/MCH blends have been reported at unique combinations of T and P in a sub/supercritical flow reactor. Nickel partides in the presence of supercritical MCH were found to facilitate the growth of graphitic filaments which could contribute to fuel line clogging. These smooth continuous filaments created under low temperature supercritical conditions are unique in their own right.
