The oxygen concentration in the oxidizer is varied in the range from 0.18 to 0.22(mole). PAHs measurement is performed by a gas chromatograph mass spectrometer (GC/MS). It is found that PAHs concentrations in the flame increase along with the increase of the oxygen concentration. This result shows that the increase of the oxygen concentration will promote soot formation in diffusion flames. The responses of Xi/Xc6H6, which is the mole fraction ratio of the species i to benzene, to the change of the oxygen concentration are also examined to elucidate PAHs formation mechanism. In the naphthalene (2 rings) formation process, H-abstraction-C2H2-addition (HACA) mechanism would be more dominant than Marinov\u0027s model, in which the combination of 5-membered ring radicals contributes to PAHs formation. On the other hand, in phenanthrene (3 rings) formation process, not only HACA mechanism, but also Marinov\u0027s model can be responsible for its formation.", "subitem_description_type":
