✦ Synopsis

The size of soot particles formed during the shock tube pyrolysis of toluene was measured by laser Doppler velocimetry. The particle size appeared to be of the order of a micron, i.e. about an order of magnitude higher than previously reported in the literature. This result indicates that la) agglomeration of the primary soot spheres takes place prior to the onset of cooling and (b) the use of the Rayleigh limit of the Mie scattering theory for the determination of absolute soot yield may be invalid and may lead to an overestinration of the conversion of hydrocarbon to soot.
