| Abstract: | To help in ascertaining methane content of lignite reservoir in China,the isothermal ad-sorption measurements of methane have been performed on moisture-equilibrated coals of some typical lignite-bearing basins,which comprise maximum reflectance of vitrinite(Ro,max) ranging from 0.24% to 0.50%.Related to other coal properties,our analysis shows that methane adsorption of lignite is mainly affected by coalification,as well as by maceral composition,moisture content,and seam temperature.Maximum methane capaci... |
