Effects of oxygen-enrichment and CO2 dilution on the physicochemical properties of soot in a propane laminar diffusion flame

Key Points

• Soot physicochemical properties significantly change with oxygen-enrichment and CO2 dilution, affecting combustion efficiency.
• The study shows that varying CO2 dilution levels alongside oxygen enrichment alters soot composition and morphology.
• Observational analysis of propane laminar diffusion flames revealed these chemical interactions under controlled conditions.
• Findings suggest potential adjustments in combustion processes could improve emissions control, promoting cleaner energy solutions.
