Soot formation from heavy hydrocarbons representatives of diesel fuel 2001-24-0026
Soot formation from heavy hydrocarbons (n-hexadecane,
decahydronaphtalene, N-heptylbenzene and 1-methyl-naphtalene) was
studied behind reflected shock waves, using a light extinction
technique. The highly diluted mixtures (99 to 99.8% of argon) were
heated between 1300 and 2700 K. The pressure ranged from 650 to
1800 kPa. Soot induction delay times, growth rates and yields, were
determined under pyrolysis and for two equivalence ratios (5 and
18). The effect of aromaticity, oxygen content, temperature and
pressure on these parameters were investigated.
Samples of soot particles formed behind shock waves and
collected after experiments have been analyzed by transmission
electron microscopy for a magnification of 5x10 4 in order to
determine the size of elementary spheres. This parameter was
studied in relation with the experimental conditions.
