Impact of tectonic deformation on coal methane adsorption capacity by Wu Li, Bo Jiang, Yan-Ming Zhu

“…At a pressure of 12 MPa, primary coal (N32) showed Langmuir volume (V L ) values of 15.38, 9.58, and 7.86 cm 3 /g and Langmuir pressure (P L ) values of 3.82, 2.07, and 1.81 MPa at temperatures of 30°C, 50°C, and 70°C, respectively. (3) The Langmuir volume appears to have a linear relationship with parameters I D1 /I G , Al/OX, and A-factor, as well as a parabolic curve relationship with f a , thereby illustrating that increases of apparent aromaticity can raise CH 4 adsorption on coal.…”
