Abstract
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 Ω of methane adsorption on the sorbents under study Ω 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 Ω 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.
