Özet

Five Turkish coals and macerals were subjected to supercritical toluene extraction at 400 degrees C and 100 atm The extracts were separated into three fractions, namely preasphaltene, asphaltene and oil. Oil fractions 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 obtained from the supercritical extraction of whole coals and of their corresponding maceral concentrates.
