The use of a new method for the measurement of adsorption on entirely microporous adsorbents permits the study of the absolute adsorption of gases and vapors in a broad range of adsorption equilibrium parameters. The methane adsorption isosteres on PAU-10 microporous activated charcoal are satisfactorily approximated by straight lines in the entire temperature range (120-600/sup 0/K) and pressure range (0.1 Pa - 20 MPa). The adsorption isosteres interrupted on the saturated vapor pressure line then extend linearly in the hypercritical region.
