The pyrolysis and combustion behaviour of a set of 11 Canadian coals with different ranks (lignite to low volatile bituminous) and maceral compositions has been investigated by TGA techniques. Temperature programmed heating of the coals was carried out both under nitrogen and under air, and the weight loss rates occurring in the two experimental conditions were compared in the whole temperature range...
Permian coal-bearing strata occur in a number of intracratonic rift basins in Tanzania. This study examines coals, shales and mudstones of the Namwele-Mkomolo, Muze and Galula coalfields (Rukwa basin) by coal petrological, palynological and rock eval techniques.
