    Experimental Study on the Pore Structure of Middle- and Low-Rank Coal and Its Influence on Methane Adsorption by Gaini Jia, Ming Yang, Xuebo Zhang, Lei Liu

    Published 2022-01-01
    “…Within 1 h of methane inflation, the methane adsorption capacity of middle-rank coals such as Henan Pingdingshan (PDS) and Shanxi Wangzhuang (WZ) and Xinjiang low-rank coals (XJ) increases by 36.4%, 31.7%, and 35.8%, respectively, and as the inflation time is extended to the cumulative inflation of 10 h, the order of the increase in methane adsorption capacity is still PDS>XJ>WZ. (2) The pore types of the experimental coal samples are mostly wedge-shaped pores and ink bottle-shaped pores. …”
