    “…In this study, the sub-samples enriched in a specific maceral group with different coal ranks and particle sizes were obtained by centrifugal flotation experiments. Then, experiments containing low-temperature N(2) isotherm adsorption (LT-N(2)GA), low-temperature CO(2) isotherm adsorption (LT-CO(2)GA), and methane isothermal adsorption were carried out on the sub-samples to quantitatively analyze the evolution characteristics of pore structure and adsorption properties of different maceral groups. …”
