| Abstract | Knowledge of the adsorption behavior of coalbed gases is critical for optimum development of production processes to recover coalbed methane and/or to sequester CO2 in coalbeds. In the context of this study, the adsorption isotherms of pure methane, nitrogen and carbon dioxide on three selected coals having different properties at 319.3 K and pressures to 12.4 MPa were measured using a volumetric method. Significant differences in adsorption capacity have been observed for different coals. Specifically, Fruitland coal has the highest capacity followed by Illinois-6 and Lower Basin (LB) Fruitland coal. Furthermore, the relative affinities for CO2 vs other gas also differ for different coals. These differences might be due to the heterogeneity of the coal’s surface, the coal’s surface area and the ash content of the coals. In this study, the OnoKondo and the Loading Ratio Correlation (LRC) models are used to correlate the adsorption data. The evaluation results indicate that both models are capable of representing the system considered within their experimental uncertainties. |
