Abstract

Adsorption isotherms of N2, Ar, CO2, and H2 were measured on selected activated carbons representing various pore size distributions. Isotherm data were analyzed using the DFT method. A good agreement was obtained between N2 and Ar results in a wide range of pore sizes. Both N2 and Ar results agree with CO2 anal. at 273 K in the range of small micropores where CO2 anal. is most applicable. Also, in this range of pores the anal. of H2 adsorption data at 77 K gives results which are consistent with the results obtained from the more conventional vapor-phase adsorptives. However, the range of PSDs calcd. from H2 data extends to pore sizes smaller than those that can be characterized by other adsorbates. [on SciFinder(R)]
