Changes in Pore Structure of Coal Associated with Sc-CO2 Extraction during CO2-ECBM

Supercritical CO2 (Sc-CO2), a supercritical solvent, can extract small organic molecules (fluid) from coal, changing pore structures to affect gases storage and migration in the coal matrix. Five undeformed coals before and after the second coalification jump were collected to simulate Sc-CO2 extrac...
