The Effect of the Low Rank Coal Lithotypes on the Sorption of CH 4 and CH 4 /CO 2 Mixtures The aims of this work was the assessment of the effect of maceral composition of low rank coal on methane and methane/carbon dioxide mixture sorption capacity. This issue was ad- dressed by performing adequate sorption experiments carried out at 298 K at low pressure on basic coal sample and two lithotypes concentrates, vitrain and durain, isolated from the original coal sample. The results of methane sorption experiments show that for vitrain and durain the course of isotherms is very close and the results for basic sample are higher than those of con- centrates. The sorption capacity of the gas mixture is the highest in the case of vitrain and the lowest for durain and has a medium value for basic coal. The tendency of sorption capacity of CO 2 to depend on maceral composition was indirectly confirmed. Desorption hysteresis was observed for every coal-gas system under investigation. The Dubinin-Radushkevich equation shows a very good agreement with all the experimental data.
