What is Soot Concentration and Absorption Coefficient in a Low-pressure Flame about?
Soot concentrations at different positions through the carbon formation zone of a premixed acetylene/ oxygen flat flame at 20-mm Hg were evaluated by measuring the attenuation of a laser beam passed through the flame. The required soot absorption coefficients were measured in the same optical system by replacing the flame with standard soot samples deposited on glass slides in a molecular beam sampling instrument. The average spectral absorption coefficient of the young soot studied here (5160 cm "1 ) is substantially smaller than the value (76.000 cm "1 ) often used for full-grown soot clusters, which agrees qualitatively with the expected effect of graphitization and decreasing H/C ratio in the aging of soot. In comparison with soot-particle concentrations measured previously under the same flame conditions using molecular beam sampling and electron microscope analysis of beam deposits, the concentrations observed here are substantially larger in the regions of particle nucleation and rapid surface growth, but in good agreement farther downstream in the region of predominant particle coagulation. The early difference is attributed to absorption by large hydrocarbon species whose
