Adsorption of Pure Methane, Nitrogen, and Carbon Dioxide and Their Binary Mixtures on Wet Fruitland Coal

Development of Volume Modified Sorption Model and Prediction for Volumetric Strain of Coal Matrix

“…이를 수식으로 표현하면 식 (1)은 다음과 같 이 재구성된다. [12]. IAS모델은 혼합가스의 흡착상을 가스상과 평형에 있는 용액으로 간주하는 이론으로 액체에 대 한 기본 열역학방정식들이 흡착상에 적용된다고 가 정한다.…”

“…We also applied this volume modified pure gas adsorption model to the IAS model to describe gas adsorption and volumetric strain for mixed gas. This modified-IAS model fitting experimental data by Hall et al(1994) improved accuracy of mixed gas adsorption calculation compared with conventional model. …”

Sequestering Carbon Dioxide in Coalbeds

“…The experimental apparatus, shown schematically in Figure 1, has been used successfully in previous measurements [1,2]. A brief description of the experimental apparatus and procedures follows.…”

“…As a precursor to the data acquisition, the apparatus was thoroughly re-tested and revised as necessary for operations in the present project. Details of the equipment design have been described previously [1,2]. A brief description of experimental methods and procedures is given in the following section.…”

“…In addition, we have conducted CO 2 and methane uptakes on four samples, including (a) a widely used commercial activated carbon, BPL from Calgon Carbon Corp. (reference material); (b) an Illinois #6 bituminous coal from the Argonne Premium Coal sample bank; (c) a Fruitland Intermediate coal sample; (d) a dry Fruitland sample. The results are as expected, except for a greater sensitivity to the outgassing temperature.…”
