The depletion mechanism of polycyclic aromatic hydrocarbons (PAHs) in a partially-premixed methane-air counterflow flame is investigated. The oxygen added to fuel flow is varied in the range from 0.0% to 5.0%, corresponding equivalence ratio is from ∞ to 30, respectively. 1-D structures of PAHs and C3, C4 hydrocarbon species are analyzed by a gas chromatograph mass spectrometer (GC/ MS). Numerical analysis (based on GRI-mech 3.0) for corresponding 1-D flames is performed to obtain detail flame structure up to C2 class of hydrocarbons. As partial premixing proceeded, most of PAHs except for cyclopentadiene (C5H6) in the flame are decreased, while C3, C4 species remains as nearly constant value. In order to elucidate major PAHs depletion pathways, possible mass production rate is calculated by using experimentally-measured PAHs concentrations and numerically-predicted radical concentration. It is indicated that benzene (C6H6) is oxidized mainly by O2 and HO2 and decreased as the partial premixing proceeded, then subsequent PAHs formation is decreased according to the benzene depletion. In addition, higher-class of PAHs could be decomposed by way of benzene and cyclopentadiene.
