## Supercritical-gas extracts of two lignites have been obtained; the yields were similar to those reported for mature coals. The extracts have been fractionated and many of the compounds they contain have been identified by gas chromatography/mass spectrometry. The formation and yields of these c
The gasification rate of chars from the supercritical fluid extraction of coals was measured in a carbon dioxide atmosphere using an isothermal thermogravimetric analyzer. The chars were prepared by pyrolysing residual coals extracted with toluene or toluene-tetralin mixtures as supercritical solven
