Methane Adsorption Capacity of Deep-Buried Coals Based on Pore Structure in the Panji Deep Area of Huainan Coalfield, China

Pore structure characterization of deep-buried coals and its implications on methane adsorption capacity are of great significance for further understanding the adsorption mechanism of methane molecules by pores in deep strata. In this study, a series of several experiments, including high-pressure mercury intrusion porosimetry, N2/CO2 adsorption, field emission scanning electron microscopy, and methane adsorption, were used to investigate the...
