Abstract
Five Turkish coals and macerals were subjected to supercritical toluen e extraction at 400 degrees C and 100 atm The extracts were separated into three fractions, namely preasphaltene, asphaltene and oil. Oil fr actions were further separated into paraffinic, aromatic and polar sub -fractions. This paper discusses the spectroscopic and chromatographic analysis of these paraffinic, aromatic and polar sub-fractions obtain ed from the supercritical extraction of whole coals and of their corre sponding maceral concentrates.
