Abstract:

Soot is a common by-product resulting from the combustion of fossil fuels. Release of soot into the atmosphere by combustion processes contributes to environmental and health hazards and decreases the efficiency of combustion processes since carbonaceous particulates represent incomplete combustion. On the other hand, soot formation is desirable in certain applications such as industrial furnaces since the presence of soot greatly enhances radiative heat transfer. The challenge is to be able to control soot formation for a specific task. Unfortunately, understanding the mechanisms responsible for soot formation remains a daunting task. The major steps in soot formation consist of fuel pyrolysis, polycyclic aromatic hydrocarbon (PAH) formation, particle inception, coagulation, surface growth, carbonization, agglomeration, and oxidation. The process of soot inception is the least understood aspect of soot formation.
