Abstract

This study improves the characterization and measurement of gas interactions with coal porosity. Due to the complex structural and chemical properties present at various scales, natural micropore media such as coals (i.e. shales, mudstone) are difficult to define. Large surface area for gas sorption on micropore materials. The ability to estimate gas reserves, flow, and storage for increased recovery and CO2 sequestration is crucial in oil and gas applications. Other uses include industrial CO2 collection, hydrogen storage on sorbent surfaces, and ammonia synthesis heterogeneous catalysis. To understand the gas–solid interaction, high-resolution experiments are required. To increase quantitative agreement between CT-derived results, micro- to macro-millimeter CT imaging was used on coal samples (low rank). The importance of gas sorption in sophisticated micropore media is highlighted in relation to CT imaging mass balance data. On the Balingian, Sarawak sample, micro scan CT revealed that the operation may be reproduced on a lab size. These findings demonstrated the DRB method’s dependability for a wider deployment of digital adsorption research in micropore geomaterials.
