More specifically, three important heterogeneous processes, namely, adsorption, ion exchange and catalysis, are analysed, from fundamental kinetics to reactor design with emphasis on their environmental applications.
separation [5, 97–99], and so forth. The PSA processes are normally associated to low energy consumption when compared to other technologies [12, 55, 100–102]. As a rule of thumb, pressure swing adsorption is preferred to other processes when the concentration of the components to be removed is quite important (more than a few per cent).

Adsorption reaction of water on alkali halide nanocrystals gives a model of deliquescence of bulk salts. In this research, we investigate the adsorption reactions of water on sodium halide nanocrystal ions, for the purpose of unveiling the deliquescent processes of bulk crystals. The nanocrystals, which are composed of alkali cations
Adsorption and desorption are often used adjectivally to indicate the direction from which experimentally determined adsorption values have been approached, e.g. the adsorption curve (or point) and the desorption curve (or point). Adsorption hysteresis arises when the adsorption and desorption curves deviate from one another.

instrument that allows measurement of heats of adsorption for larger organic molecules, e.g. Bz and naphthalene, on the Pt(111) surface [32, 37, 38, 45]. The adsorption of Bz on metals has also been intensively studied theoretically. First-principles calculations were predominantly carried out using density-functional theory
adsorption parameters on its basis is substantiated. The controversial matter of analogy of the adsorption process with the volumetric dissolving is discussed. Introduction The phenomenon of adsorption from solutions on the surface of solid adsorbents is a basis of numerous phisico-chemical and biochemical processes.
Deep knowledge of adsorption processes allowed A.V. Kiselev to study the chromatographic processes, which allowed him to create a new direction - gas-adsorption chromatography. First of all it was necessary to make adsorbents for chromatography, because adsorbents used before could not satisfy the needs of chromatography.
