Measurements of CO₂ sorption are taken by the weighting method, using the specialist equipment: a low-pressure microbalance (Sartorius). Experiments are performed at 3 temperatures: 272, 298 and 313 K. Low-pressure sorption data for the coal-gas systems are compared with results obtained at elevated pressures. Coal sample come from the brown coal mine in Belchatow (Poland). Experimental data supported by the IST method are used to transform the isotherms to obtain the general isotherm and to generate the absolute sorption isotherms. It appears that the method agrees well with experimental data, which means that it well captures the behavior of the coal-CO₂ system.
