โœฆ Synopsis

The application of high-performance liquid chromatographic fractionation using a column-switching technique to the identification of monomethylated polycyclic aromatic hydrocarbons by capillary gas chromatography and high-resolution (Shpol'skii effect) fluorescence spectroscopy is described. The column-switching technique with silica and aminosilane columns permitted the rapid fractionation of both aromatics and each aromatic ring type in heavy oils. The existence of methylphenanthrenes, rnethylchrysenes and methylbenz[a]anthracenes in Kuwait 340-500ยฐC distillate was confirmed by the two methods.

In this paper, the types and concentrations of polycyclic aromatic hydrocarbons (PAH) formed during combustion of heavy oils are presented. A heavy fuel oil and its emulsion with 10% of water (ElO) were burned in a combustion chamber and samples of the combustion products, including PAH, were collec
