| Abstract: | Samples of coals from several coalbeds in Indiana were analyzed for CO2 and CH4 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 CO2 and CH4 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 m3/ton (128-202 scf/ton) of CH4 and 19.5-24.6 m3/ton4 (624 to 788 scf/ton) of CO2. The ratio of CO2/CH4 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 (Ro from 0.48 to 0.62%) but of varying petrographic composition, and CO2 sorption volumes appear to be positively correlated to the content of maceral telocollinite. ?? 2004 Elsevier B.V.
