Experiment of benzene pyrolysis is carried out to understand the effect of temperature on soot particles and aggregate formation. Two reactors which have different cross sectional area are used in order to change the gas temperature profile and the residence time in the reactor. From the analysis of soot aggregates, the soot shape is classified into four categories (spheroidal, ellipsoidal, linear and branched). Numerical simulation of soot formation in benzene pyrolysis is also conducted. The numerical results indicate that the surface growth occurs with an increase in residence time at low temperature region. In addition, it is shown that the concentration of soot particles has a great influence on the aggregation of particles.
