Experimental Investigation for Pore Structure and CH4

With the increase of total pulverizing time, the coal particle size is gradually decreased. Furthermore, compared with the pre-pulverized samples, the porosity, pore volume, and surface area of post-pulverized samples are increased, indicating that the closed pores are destroyed to be open pores during the pulverization process.

Experimental Investigation of Pore Structure Damage in

Results indicate that the pulverization process has no remarkable influence on the proximate properties of the coal, while the pore structures are evidently modified. The pulverization process significantly increases the specific surface area and pore volume (measured by N2 adsorption) of the coal, which favors gas adsorption and diffusion.
