Multiple Fractal Characteristics of Nanoscale Pore Structure and Surface Morphology in Low-Rank Coal Macerals: Implications for Coalbed Methane (CBM) Exploitation
Maceral composition critically controls nanoscale pore structure and influences methane behavior in low-rank coal reservoirs, yet the role of individual macerals remains inadequately quantified. Therefore, vitrinite, semifusinite, and fusinite of low-rank coal were characterized by atomic force microscopy (AFM) and mic...
