In the present study, a sooting flame was formed in a reduced-pressure combustion chamber using the vitiated coflow burner with a premixed flame of methane and oxygen for the surrounding flame and premixed flame of toluene, methane and oxygen for the center flame. Collected soot samples were analyzed using the high performance liquid chromatography (HPLC) and a gas chromatography to determine the fullerene content of soot and the species of PAHs under various conditions. Effects of pressure and equivalence ratio to the formation of the PAHs and fullerenes and the branching mechanism between fullerene and soot were discussed. When the fullerene content in soot samples was relatively high, the fractions of anthracene and benzo [a] anthracene were relatively high. When the fullerene content in soot samples was relatively low, the fractions of phenanthrene, flouranthene and pyrene were relatively high. Under the same pressure condition, there was an optimal flow rate of toluene in the center flame for formation of C80 and C70 of which range became wider with the decrease of pressure condition.
