RESUMO
This work reports the studies performed with two kinds of particulated materiais generated from combustion: cenospheres, in the case of the combustion of oils with high C/H ratio, and soot, in the case of LPG and mixtures of LPG/1butanol and LPG/Methanol combustion. The morphologies of these particulated materiais and the formation of PAH (polycyclic aromatic hydrocarbons) in the combustion processes were determined. The influence of reburning, in the case of cenospheres, and the addition of alcohols, in the case of soot, on these properties were also evaluated. The action of reburning on the cenospheres resulted in an increase of the porosity of this particulated material, as well as in a reduction oh the quantity of P AH present in cenospheres. The addiction of both 1-butanol and methanol vapor in the combustion of LPG resulted in an increase in the size of the soot particle agglomerates as well as in a reduction in the quantity of the aromatic compounds present in this material. The changes observed in the characteristics of the soot collected in the flame region, where this particulated material is formed, demonstrated the effect of the alcohol vapor added to the LPG on the mechanism of aromatic compound formation and on the process of particle agglomeration
