This report describes experimental studies of soot initiation in the pyrolysis and combustion of the aromatic model fuels toluene and pyridine. These molecules were chosen as generic examples of the aromatic component of synthetic fuels which is thought to dominate soot formation in combustion of these fuels. The experiments were conducted in a shock tube over the ranges 1300 to 2500/sup 0/K and 0.2 to 0.8 atm, using optical diagnostics to monitor the appearance of soot particles and the kinetic behavior of several gas phase species. Major results of this study include (1) validation of the applicability of optical diagnostics in sooting systems; (2) observations of strong influence of fuel molecular structure on sooting behavior; and (3) postulation of a conceptual sooting mechanism to account for the existing data base. 66 figures, 6 tables.
