Soot formation from polycyclic aromatics. Technical progress report, March 1, 1981-August 31, 1981
During the reported period, progress has been made in the following areas: (1) a conceptual model for soot formation during pyrolysis of polycyclic aromatics has been finalized; (2) Measurements of soot particle size were made during the pyrolysis of toluene. The particle size, determined by a laser scattering technique, appeared to be of the order of microns, i.e. an order of magnitude higher than previously reported in the literature. This result supports our conjecture, suggested in the previous report, that the use of the Rayleigh limit of the Mie scattering theory for the absolute soot yield determination is invalid and leads to overestimation of the conversion to soot; (3) the pyrolysis of acetylene has been studied within the temperature range of 1645 to 3106/sup 0/K, at pressures of 0.052 to 0.81 MPa, and the toluene concentration in argon of 3.47 to 39.0 kmol/m/sup 3/. The results support the unified conceptual model for soot formation during the pyrolysis of hydrocarbons suggested in our previous report.
