Temperature Extrapolation of Henry's Law Constants and the Isosteric Heat of Adsorption. [PDF]
J Phys Chem B, 2022 Computational screening of adsorbent materials often uses the Henry's law constant (KH) (at a particular temperature) as a first discriminator metric due to its relative ease of calculation. The isosteric heat of adsorption in the limit of zero pressure (qst∞) is often calculated along with the Henry's law constant, and both properties are informative ...

Temperature Dependence of the Isosteric Heat of Adsorption
Adsorption Science & Technology, 2001 Direct calorimetric measurements of the isosteric heats of adsorption of (a) pure CO 2 on a strongly heterogeneous adsorbent (silicalite with an alumina binder) and (b) pure N 2 on a mildly heterogeneous adsorbent (5A zeolite) at different temperatures ...

Isosteric heat of adsorption for water adsorbed on ThO2
CHIMIA, 1972 The isosteric heat of adsorption for water on ThO2 was measured as a function of the surface coverage. The ΔHst-values referring to the formation of the second and third monolayer are smaller than the heat of liquefaction of pure water.
