Abstract
The purpose of the work presented in this paper was to adapt the Multiple Sorption Model (MSM), originally developed for hard coals, to study sorption in lignites. It also includes an analysis of the sorption process of small molecule compounds in lignites. Measurements were made of the sorption isotherms of carbon dioxide in two samples of lignite from Polish collieries at different temperatures (298, 313 and 323 K) and in the pressure range up to 5 MPa. Subsequently, simulations of the isotherms for selected carbon dioxide-lignite systems were performed using the MSM. They were evaluated using the empirical isotherms until agreement of the isotherms was attained and the parameters of the sorption system reached reasonable values. Surprisingly, a low contribution of absorption was found in the overall sorption process probably as an effect of the high porosity of the sample and the presence of a large number of high-energy sites on the coal surface. Sorbate molecules occupied these high-energy sites on the surface and did not migrate to the absorption subsystem.
