The use of coals with high sulphur contents is an important issue for Donetz Basin, where nearly 70% of the coal stock contains more than 3% sulphur. Sulphur content is a main criterion of fuel quality and is connected to a coal's genetic type by reductivity.
Three pairs of Donetz low-rank bituminous coals of different genetic types (reduced coal - RC and low-reduced coal - LRC) were studied in this work. A comparative study of the thermal destruction process of RC and LRC coals, and of the distribution of sulphur in the semi-coking products has been carried out.
