Particulate matter (PM) formed by combustion of hydrocarbon fuel has harmful effect on environment and human health. Therefore, it is required to reduce. In generally, the main component of PM is soot, and its precursor is thought polycyclic aromatic hydrocarbon (PAH). In this study PAH and PM formation by pyrolysis and oxidation of dodecane under low temperature condition (1073K～1323K) using a flow reactor were investigated under φ = ∞, 6.2 and 2.8 conditions. In addition, numerical analysis for PAH mass concentration was also performed using a CHEMKIN-Pro software. As a result, the lower amount each PAH was formed under higher oxidation concentration condition. The lower amount PM also formed under higher oxygen concentration. Therefore, it was found that the amount of both PAH and PM under with oxygen condition was lower than under without oxygen condition.
