Influences of supercritical carbon dioxide fluid on pore morphology of various rank coals: A review [PDF]

Energy Exploration & Exploitation, 2020
Supercritical carbon dioxide is known to change the pore structure of coals and thus affect their carbon dioxide sequestration capacity. In this study, supercritical carbon dioxide dependence of pore morphology of coals was reviewed.
