✦ Synopsis

Using the van Krevelen diagram (atomic O/C vs H/C) and by plotting calorific value vs volatile matter, Australian coals, ranging in age from Permian to Miocene, were analysed. In the van Krevelen diagram method groups of coals of particular ages or from particular areas/seams within coalfields plot in well-defined parts of the diagrams. The findings and an evaluation of the analyses are presented in this article. 99102336 Changes in the structure of coals of different rank due to oxidation-effects on pyrolysis behavlor de la Puente, G. et al.
