摘要：

The chemical structure of a methane counterflow diffusion flame doped with small amounts of either JP-8 or a jet fuel surrogate was analyzed by gas sampling via quartz microprobes and subsequent GC/MS analysis. This jet-fuel initial oxidation is consistent with the anticipated chemical kinetic behavior, based on thermal decomposition of large alkanes to smaller and smaller fragments and the survival of ring-stabilized aromatics at higher temperatures. The surrogate captures the general trend but incorrectly mimics the behavior of some species such as benzene and ethylene. Furthermore, the comparison in the behavior of large alkanes is only qualitative, because of difficulties in separating the components of JP-8 as a result of isomerism.
