Fractal characterization of adsorption-pores of coals from North China: An investigation on CH4 adsorption capacity of coals
TL;DR: In this paper, the fractal analysis for 13 fresh coal samples (R o from 0.79 to 4.24%) in North China was conducted to better understand the characteristics of adsorption-pores (pore diameter <100 nanometers).
Journal ArticleDOI
Pore structure and its impact on CH4 adsorption capacity and flow capability of bituminous and subbituminous coals from Northeast China
TL;DR: In this article, the surface fractals of pore surface were analyzed with surface fractal dimensions and the results showed that the more irregular surface, the more inhomogeneous pore structures is, meaning more surface area and then stronger adsorption capability.
