The Determination of Rate-Limiting Steps during Soot Formation

Abstract

A detailed model for soot formation has been developed for describing soot production in laminar, premixed flames. The analysis is based on detailed chemical kinetic modeling, a simplified inception model, kinetic calculations of surface growth, and coalescing particle collisions. Several different models for surface growth are compared. Sensitivities to flame parameters and many of the assumptions were determined. The importance of inception to the amount of soot formed has been verified for several premixed flames. Comparisons have been made to several flames with varying stoichiometry, temperature, fuel type, and pressure. A mechanism for the pyrolysis of cyclopentadiene has been developed. In addition, mechanisms for the addition of acetylene to cyclopentadiene to form toluene are discussed.
