摘要：
Adsorption of methane on twelve microporous carbon adsorbents of different origin and structural and energy characteristics was studied at the pressures up to 20 MPa. Specific capacities have been calculated for methane adsorption storage systems. The effectiveness of adsorption accumulation was analyzed in terms of structural and energy characteristics, packing density and thermodynamic parameters of methane adsorption. Differential molar isosteric heats of adsorption and absolute efficiency of adsorption accumulation systems were evaluated. The effects of increased packing density and proper shape of adsorbent material on the adsorption accumulation efficiency were considered. It was shown that a selection of an adsorbent with the most optimal porous structure and density should be adjusted for thermodynamic parameters of accumulation system.
