Adsorption of Carbon Dioxide onto Model Carbon Structures with Slitlike Micropores

Carbon dioxide adsorption onto model supramolecular structures with slitlike micropores was calculated based on the Dubinin theory of volume filling of micropores using the linearity property of isosteres. Models of carbon adsorbents with slitlike micropores with a width ranging from 0.5 to 2.5 nm o...

Description
Summary:Carbon dioxide adsorption onto model supramolecular structures with slitlike micropores was calculated based on the Dubinin theory of volume filling of micropores using the linearity property of isosteres. Models of carbon adsorbents with slitlike micropores with a width ranging from 0.5 to 2.5 nm obtained by successively eliminating one, two, etc., up to seven layers of hexagonal carbon in the crystal lattice of graphite were used in calculations. The integral energy of adsorption was calculated for the model structures and commercial carbon adsorbents. The dependence of the gravimetric density of carbon dioxide on temperature and pressure was found.
