In order to go deep inside the nature and chemistry of combustion produced particles a kinetic modeling approach is proposed. It is based on the modeling of gas-to-particle transition through sections in which 100 lumped species are used having a C number ranging from 24 to 4x10(8) and H/C ratio ranging from 0.2 to 1. This approach gives the possibility to numerically follow not only the mass evolution of particles but also their size distribution function and hydrogen content. The model is tested in a premixed flat flame of ethylene/oxygen with C/O=0.8. Comparison of modeled results with experimental data is reasonable both in terms of concentration of species and H/C ratio.
