摘要：
The Dubinin theory of volume filling of micropores and the linearity of adsorption isosteres were used to calculate the adsorption of hydrogen on model microporous adsorbents with slitlike pores. In calculating, the model adsorbents were considered the micropores of which were formed through a progressive removal of one, two, and so on to seven layers of hexagonal carbon in a graphite crystalline structure, while the micropore sizes varied within a range from 0.5 to 2.5 nm. The integral energy of adsorption was evaluated for the model structures and most of industrial carbon adsorbents. The obtained results were compared with experimental data. Dependences of the gravimetric density of hydrogen on temperature and pressure were analyzed.
