Krypton adsorption on microporous adsorbents at higher pressures

Abstract

The krypton adsorption isotherms were measured on AUK microporous carbon adsorbent in the range of pressures from 1 Pa to 6 MPa and temperatures of 177.7—393 K. With adsorption isotherms in the same range of pressures and temperatures, the krypton adsorption isosteres were calculated. The derived curves are well approximated with linear functions. With the adsorption isosteres, differential molar isosteric adsorption heat curves were plotted vs. adsorption and temperature. The received results were compared with the reference data of the krypton adsorption on Carbolac active carbon.
