Soot formation in combustion is a complex process involving fuel breakdown, particle growth, and aggregation. Understanding these mechanisms is crucial for developing strategies to reduce harmful particulate emissions in various combustion systems.
Soot oxidation competes with formation, influenced by temperature, fuel composition, and oxidizing species. Particle characteristics and distribution evolve throughout combustion, affecting light scattering, transport, and health impacts. This knowledge guides emission reduction efforts.

Soot precursors originate from fuel and incomplete combustion processes
Fuel molecules break down into smaller hydrocarbon fragments under high temperatures
These fragments recombine to form larger, more complex molecules
Polycyclic aromatic hydrocarbons (PAHs) emerge as key intermediates in soot formation
PAHs consist of multiple fused aromatic rings (benzene, naphthalene, anthracene)
PAH formation occurs through various pathways including:
