Abstract

The adsorption processes of nitrogen and neon onto carbon adsorbents were investigated at pressures between 1 and 1.013 × 105 Pa and temperatures of 77 and 27 K. The isotherms of adsorption were measured, the specific micropore volumes were determined, and the characteristic energies of adsorption were evaluated for these adsorption systems. The theory of volume filling of micropores was utilized to calculate the isotherms of neon adsorption onto different microporous carbon adsorbents using the affinity coefficients.
