ResumoInvestigations of low- and high-pressure sorption kinetics were carried out on three coals of different rank, with simultaneous tensometric measurements of the coal dilatation. The observed phenomena, occurring under the influence of water vapour and carbon dioxide, are explained on the basis of the copolymeric model of coal. The parallelism of sorption and dilatometric processes was observed for both sorbates while full reversibility was found only for carbon dioxide.
