Abstract
Multimode size exclusion chromatography of complex mixtures from coal pyrolysis using a poly-(divinylbenzene) column and dichloromethane mob ile phase permitted the separation of the mixture into two fractions e nriched in either substituted (XPAC) or unsubstituted (HPAC) polycycli c aromatic compounds. The XPAC/HPAC ratio, a parameter easily obtained by this method, was found to be a useful indicator of the degree of t hermal treatment of coal and other fossil fuels. The sensitivity of th e technique allowed it to be applied to the characterization of microg ram-level samples produced by small laboratory-scale pyrolysis furnace s.
