Determination of the Adsorption Isotherms of Hydrogen on Activated Carbons above the Critical Temperature of the Adsorbate over Wide Temperature and Pressure Ranges

Abstract

We present a detailed comparison between experimental adsorption measurements and the excess adsorption predicted by the Ono−Kondo lattice model. The study was performed for high-pressure adsorption of hydrogen above the critical point on microporous adsorbents. The experimental adsorption isotherms of hydrogen on the activated carbon AX-21 as well as others are compared with those of theory over the temperature range of 77−273 K and for pressures of up to 6 MPa.
