Soot samples produced by the combustion of gasoline, kerosene, light oil, three types of heavy oils, tar, light and heavy naphtha, soybean oil, olive oil, and seven alkanes were pyrolyzed at 590°C by a Curie point pyrolyzer and evaluated by gas chromatography/mass spectrometry (GC/MS).
Isoquinoline, dibenzofurane, and naphthalenecarbonitrile in the tar soot and ethylnaphthalene and dimethylnaphthalene in the soots of heavy oil and tar were useful specific components for identification of the soots.
In addition, sulfur containing compounds such as dibenzothiophene, methyldibenzothiophene, dimethylnaphtho[2,3-b]thiophene were identified in the soot of light oil, three types of heavy oils, tar, and heavy naphtha, all of which contain sulfur considerably.
