Sep 19, 2019 · Pressure: Pressure is generally considered a minor influence on coalification and rank (van Krevlin, 1961; Teichmüller and Teichmüller, 1979; Stach and others, 1982). During peatification and lignite stages of coalification, moisture is squeezed out of the peat and coal through compaction by the weight of overlying sediments

thermodynamic characteristics of methane adsorption of

thermodynamic characteristics of methane adsorption of

The adsorption of methane in coal depends on both pressure and temperature, and the adsorption gas content decreases as the temperature rises while increases as the pressure increases. When the gas molecule switches between the free state and adsorbed state, energy exchange is accompanied. To study the thermodynamic characteristics (adsorption heat, adsorption content, and adsorption time) of
