Description

Brown coal has been fractionated by two different methods. Firstly, extraction of the coal with decalin at 320 deg C to separate loosely bound guest material from the macromolecular matrix and secondly, the extraction with 1% caustic soda at 80 deg C to separate humic acid from the insoluble residue of the coal (humin). The various fractions have been reacted under CO and H2 in the presence of promoters previously used in coal liquefaction experiments. The products have been analyzed by a range of techniques, principally proton nuclear magnetic resonance and gas cromatography-mass spectrometry and the results used to gain further insight into brown coal structure. 8 refs., 3 figs., 4 tabs
