| Description: |
This study investigates the origin of oxygen in soot particles formed during ethanol combustion. Carbon particulate matter (PM) and flame structure were analyzed in fuel-rich ethylene and ethanol-doped (20 %) flames. Gas-phase composition was assessed using probe sampling and gas chromatography, revealing that ethanol addition had minimal impact on CO, CO2, and C2H2 formation but reduced methane and C3-C6 hydrocarbons concentration. PM was sampled at different formation stages and the total sample was analyzed using laser desorption ionization-time of flight mass spectrometry (LDI-TOFMS). A Fast Fourier Transform (FFT) approach was applied to interpret complex mass spectra. Three PM fractions were also examined: species |
