Аннотация:The isotherms of the absolute adsorption of methane on the microporous carbon adsorbent AU-1 in the pressure ranges from 30 Pa to 6 MPa and temperatures of 178 273 K were measured. The isomers of methane adsorption have been constructed on the basis of experimental data. In the coordinates ln p = f (1 / T) a the isosters are well approximated by straight lines. Based on the experimental isotherms, the differential molecular isosteric heat of methane adsorption on this adsorbent was calculated. Conclusions about the structure of the adsorbed substance, made on the basis of thermodynamic analysis, are confirmed by molecular-dynamic calculations.
