Abstract
Multilayer clustering based adsorption model (uniBET) is aimed at adsorption phenomena modeling with having regard to surface geometrical and energetical heterogeneities. Facilitation of the uniBET model formulas leads to the LBET class models. A review on uniBET model and the analysis of the multilayer heterogeneous adsorption models for characterization of porous materials of carbonaceous origin are presented.
Highlights
Adsorbents of carbonaceous origin are widely applied porous materials for adsorption of gases and liquids due to its selectivity for many substances, high specific surface area and adsorption capacity [1]
The optimization of the industrial application of porous materials of carbonaceous origin is mainly related to the proper selection of the production process conditions [2,3,4]
LBET class models were found out to be a useful tool in characterization of wide range of modern carbonaceous materials for industrial applications [4], [17,18,19,20,21]
Summary
Adsorbents of carbonaceous origin are widely applied porous materials for adsorption of gases and liquids due to its selectivity for many substances, high specific surface area and adsorption capacity [1]. These unique properties of adsorbents of carbonaceous origin and low cost production in comparison to the possibly competitive adsorbents of inorganic origin, results in a broad range of industrial applications. Our team elaborated new clustering-based multilayer adsorption theory (uniBET) comprising the surface geometrical and energetical heterogeneities to the analysis of the structure of microporous carbonaceous materials on the basis of experimental isotherms (gaseous and vapor). The paper shows short review on uniBET theory, LBET class models formulas properties and its possible applications for microporous materials of carbonaceous origin
