Abstract Experiments and numerical simulations were carried out to analyze the soot aggregate formation behavior by benzene pyrolysis. Soot was formed by the pyrolysis of 1mol% benzene (in 99mol% nitrogen) in an alumina tube, which was kept at 1573K, with variations of residence time (0.05 to LOOsec). The classification, i.e. spherical, ellipsoidal, linear and branched shape, was carried out in order to provide an overall characterization of the soot formation process. A numerical model, which was based on the work of Ivie et al. [1], assumed the particle growth and coagulation. In the present model, the shape of soot aggregate was furthermore considered by applying the specific fractal dimension (D) to the coagulation rate equation. In particular, the numerical model well predicted the soot yields, which are in good agreement with measured values in any residence time.
