The energy of adsorption of methane on microporous carbon adsorbents

Differential molar isosteric and integral heats of methane adsorption on a range of microporous carbon adsorbents of different origin have been calculated. The values of densities of integral heats Omega of methane adsorption on the sorbents under study Omega have been determined as the ratio between integral heat of adsorption and micropore volume. The dependence of density of integral heat of adsorption on standard characteristic energy of adsorption E (0) has been estimated. It has been shown that the value of density Omega increases as E (0) increases. The results of calculation of specific amount of accumulated methane V (sp) depending on energy and structural parameters of adsorbents have been presented.
