Pore Structure Evolution of Coal After Supercritical CO<sub>2</sub>–Water–Rock Treatment: A Multifractal Analysis

Pore Structure Evolution of Coal After Supercritical CO<sub>2</sub>–Water–Rock Treatment: A Multifractal Analysis

The evolution of coal’s pore structure is crucial to the efficient capture of carbon dioxide (CO<sub>2</sub>) within coalbeds, as it provides both adsorption sites and seepage space for the adsorbed- and free-phase CO<sub>2</sub>, respectively. However, the conventional singl...
