ABSTRACT
From the many of years we are dealing with the research on the system coal-gas in the aspect of outburst problems, of methane recovery and emission of greenhouse gasses. Investigations of sorption in the coal-mine gasses system, led in conditions moved close for conditions in situ, are pointing at the bigger affinity coal with CO2 account. In consequence the carbon dioxide inserted into carboniferous beds will not only be sorbed, but will also be supplanting methane gathered in them. In presented investigations the isotherms of sorption were presented appointed in a wide range of pressures and temperatures. Tests of sorption CO2 and CH4 mixtures led the selectivity of these gasses, for detecting the inversion for coal about the different degree of the metamorphism.

Od szeregu lat zajmujemy się badaniami układu węgiel-gaz w aspekcie zagadnień wyrzutowości, pozyskiwania metanu i emisji gazów cieplarnianych. Badania sorpcyjne w układzie węgiel-gazy kopalniane, prowadzone w warunkach zbliżonych do warunków in situ, wskazują na większe powinowactwo węgli względem CO2. W konsekwencji wprowadzony do utworów węglonośnych dwutlenek węgla będzie nie tylko sorbowany, ale również będzie wypierał zgromadzony w nich metan. W prezentowanych badaniach przedstawiono izotermy sorpcji wyznaczane w szerokim zakresie ciśnień i temperatur. Badania sorpcji mieszanin CO2 i CH4 doprowadziły do wykrycia inwersji selektywności tych gazów dla węgli o różnym stopniu metamorfizmu.
