| Outline of Final Research Achievements |
PM and PAH formed by low temperature (less than 1350K) pyrolysis and oxidation of hydrocarbon fuel using a flow reactor were investigated. The mass concentration of PM was obtained by the filter sampling method with a glass-fiber filter, while the mass concentration of PAH was analyzed by a Gas Chromatography. In addition, numerical simulation for PAH formation was performed using a CHEMKIN-Pro software. As a result, it was found that the mass concentration of PM increased with temperature raise under various equivalent ratio conditions (φ = ∞, 6.2 and 2.8). Therefore, it was also found that the mass concentration of PM without oxidation condition was higher than that with oxidation condition.
