Abstract
In the present study, a sooting flame was formed in a reduced-pressure combustion chamber with a premixed flame of methane and oxygen for the surrounding flame and premixed flame of toluene and oxygen for the center flame. Collected soot samples were analyzed using the high performance liquid chromatography and a gas chromatography to determine the fullerene and the total PAH contents and 22 species of PAHs under various conditions. Effects of the chamber pressure, the equivalence ratio of totluene and oxygen, the flow velocity and the chamber length to yield of soot and contents of PAHs and fullerenes were discuseed. When the chamber pressure increases, the contents of PAH and fullerene decreased with keeping a constant soot yield. There were optimal equivalence ratio and flow rate of the center flame for fullerene formation whereas flow rate of the outer flame and chamber length were not essential for fullerene formation. Such chemical species as acenaphthene, fiuorene, phenanthrene, fluoranthene and phyrene accounted for large content in total PAHs.
