Abstract
Soot formation during the pyrolysis of argon-diluted mixtures of toluene and n-heptane and of toluene and iso-octane in a reflected-shock tube was studied. Soot induction times and rates of formation measured at 632.8 nm by laser beam attenuation showed an Arrhenius dependence on reflected-shock temperature. The maximum in bell-shaped distribution of soot yield and concentration as a function of temperature decreased with increasing amount of n-heptane or iso-octane substituted for toluene. A kinetic model was used to explain the experimental trends and gave reasonable prediction of the experimental observations. The reduction in soot yield and concentration was attributed to the faster decomposition of the alkanes as well as to their decomposition products, which diverted the soot formation process from the more effective path of toluene pyrolysis to a slower route.
