J. Jagiello et al., ADSORPTION NEAR-AMBIENT TEMPERATURES OF METHANE, CARBON TETRAFLUORIDE, AND SULFUR-HEXAFLUORIDE ON COMMERCIAL ACTIVATED CARBONS, Journal of chemical and engineering data, 40(6), 1995, pp. 1288-1292
The adsorption isotherms for CH4, CF4, and SF6 are measured at three o
r four temperatures near ambient on three commercial activated carbons
. The data are reduced using a virial-type equation of adsorption. Usi
ng this equation, isosteric heats of adsorption are calculated. It is
shown that this fundamental thermodynamic quantity provides a basis fo
r differentiating between the carbons' micropore structures.
