The isotherms describing excess adsorption of SF6 and N6I6 on carbon adsorbents with different pore structures were measured at pressures of 0.001—2.4 and 0.0001—0.1 MPa, respectively, and temperatures of 298—408 E. A linear dependence of Henry

The heats of xenon adsorption on zeolite NaX at 299–467 K and 0–21 MPa were measured on a Tian-Calvet differential calorimeter. A significant temperature dependence of the heats measured at high occupancies of the adsorption surface was demonstra

Adsorptionsisothermen von n-Pentan, n-Hexan, Benzol und Stickstoff werden am Zeolith NaY und an einem Molekularsieb, das zu 99% aus SiO2 besteht (US-Ex), gemessen. Es zeigt sich, das US-Ex bidispers ist. Als Ergebnis der Dealuminierung entsteht ein S

1. The adsorption isotherms of the n-alkanes on NaX have a Heary region, which takes on a convex shape after a point of inflection, and the differential heats of adsorption in the Henry region are almost constant. Subsequently, the q(a) curves have a

1. The isotherms and differential heats of adsorption of water and benzene vapors on ultrahigh-silicon zeolite of the faujasite type (faujasil), obtained by the original method of substitution of Al atoms by Si atoms in the reaction of zeolite NaY wi

Complex relationships between the differential adsorption heats and the degree of filling are observed when benzene and toluene are adsorbed on silicalite. A possible reason for this phenomenon is either a redistribution or a reorientation of the ads

The heats of adsorption of xenon and argon in the region of the highly nonideal gas phase depend significantly on temperature. The partial molar isosteric heat capacity of the adsorbate increases sharply at high concentrations of the adsorbed molecul

1. The absolute differential calorimetric heats of adsorption were measured for Xe and Kr on NaX zeolite at 304.5 K and pressures up to ∼10 MPa. 2. Good agreement was found between the measured heats of adsorption and the calculated isosteric heats
