Sorption thermodynamic functions of nitrous oxide, N 2 O, are described for zeolites NaLSX and CaLSX in shapes of clay-bound beads. They were determined by the sorption-isosteric method (SIM) over complete ranges of sorption-phase concentration and c

Molecular mobility of oxygen, O2, and nitrogen, N2, in Carbon Molecular Sieves, CMS, was investigated using the Frequency Response, FR, technique to identify mass-transfer mechanisms and related kinetic time constants. The FR data showed that O2 mobi

The development of the sorption-isosteric method (SIM) with minimum dead volume for a direct measurement of sorption heats is reviewed. Advantages and limitations of the technique are illustrated by concentration dependencies of the isosteric sorptio

Sorption thermodynamics of nitrogen, N2, and oxygen, O2, on zeolites LiLSX and CaA were investigated using an isosteric sorption technique [Stud. Surf. Sci. Catal. 83 (1994) 209; Micropor. Mesopor. Mater. 22 (1998) 237] and molecular simulation. The

Grand canonical Monte Carlo simulation of sorption of nitrogen and oxygen has been carried out on LiLSX zeolite structures and accurate adsorption data was measured on LiLSX powder using the isosteric technique. The position of Li cations in the LiLS

Experimental measurements of heats of adsorption published in the literature are often in disagreement; differences of 10–20% are common. The three most widely used experimental methods are: (1) differentiation of adsorption isotherms at constant l
