Abstract

The chemical structures of the asphaltenes and residues from reactions of a range of brown coals with widely varying atomic H C ratios have been examined by chemical and spectroscopic methods, and have been shown to be remarkably consistent. Asphaltenes and residues from brown coals with high atomic H C ratios show a small but significant increase in incorporation of aliphatic, guest material although the main bulk of material is derived from the host component of the coal (i.e. ligno-cellulosic or tannin derived material).
