A shock tube investigation of the rate of soot formation for benzene, toluene, and toluene/n-heptane mixtures
The rate of soot formation during the pyrolysis and oxidation of rich mixtures of toluene and benzene, and the pyrolysis of toluene/n-heptane mixtures has been determined using a reflected shock technique over the temperature range of 1500-1950K and for pressures between 2.6 and 3.6 x 10/sup 5/ Pa. A laser beam attenuation technique was used to determine soot concentrations using helium-neon lasers at 632.8 and 1152.0 nm. The test gas mixtures were diluted with at least 98 mol% argon and for the pyrolysis experiments the hydrocarbon concentration did not exceed 0.35 mol m/sup -3/. The oxidation experiments employed fuel rich mixtures with equivalence ratios between 6 and 11. Rates of soot formation and soot yields exhibited an Arrhenius dependence and could be expressed by a correlation equation in a form which is also suitable for the prediction of soot limits.
