AbstractTwenty-five bituminous coals of different rank and geographical origin together with seventeen blends (binary, ternary and quaternary) prepared with these coals were studied in terms of their thermoplastic properties, which were determined by means of the standardized Gieseler test. The influence of the geographical origin of the coals on maximum Gieseler fluidity is discussed. Pyrolysis was carried out in N2 up to 1000 °C in a thermobalance. It was found that the effect of particle size on the results of the thermogravimetric analysis was negligible. The degree of additivity of the parameters derived from the thermoplastic and thermogravimetric analysis was also studied.
