Synthetical Analysis on Adsorbing Characteristic Experiment of Coal Seams

The isothermal adsorbing experiment of coal collected in different areas and coal basins with different metamorphose degrees was synthetically analyzed. It is indicated that the adsorbing capability of coal relates to many factors including the metamorphose degree of coal, temperature and pressure of the coal-bed methane-stored layer, and moisture type and content of coal etc. This experimental result was verified in practice.
