ABSTRACT
Adsorption isotherms, which describe the coal’s gas storage capacity, are important for estimating the
carbon sequestration potential of coal seams. This study investigates the reproducibility of carbon dioxide isotherm measurements on dried Tanjung Enim (Indonesia) and Fushun (China) coals. These experiments provided isotherm data for four coal samples at temperatures of 27°C or 55°C and pressures up to 6 MPa and 8 Mpa respectively. The differences among the data sets in this study appeared to be rank-dependent or specifically, the data indicated that the moisture content of these samples indicated better sorption for lower moisture content than for higher moisture content coal samples, depending on its hydration content. A number of parameters such as sample size, equilibration time, and apparatus dimensions were examined to explain the rank effect, but no trend could be found that explained the differences. The variations among the data could be attributed to different basins and depth but the same precautional procedures for removing moisture to obtain the “dried” coal were determined.
