Samples of coals from several coalbeds in Indiana were analyzed for CO
2 and CH
4 sorption capacity using a high-pressure adsorption isotherm technique. Coal quality and petrographic composition of the coals were determined to study their relationships to the volume of CO
2 and CH
4 that could be sorbed into the coal. At the temperature of 17 °C and 400 psi (∼2.8 MPa), the coals can sorb (on dry ash-free basis) from 4 to 6.3 m
3/ton (128–202 scf/ton) of CH
4 and 19.5–24.6 m
3/ton4 (624 to 788 scf/ton) of CO
2. The ratio of CO
2/CH
4 at these conditions ranges from 3.5 to 5.3 and decreases with an increasing pressure for all coals. The coals studied are of a very similar coal rank (R
o from 0.48 to 0.62%) but of varying petrographic composition, and CO
2 sorption volumes appear to be positively correlated to the content of maceral telocollinite.
