Abstract

Abstract: The aim of this paper is to study the equilibrium and dynamics of water adsorption on a commercial silica gel Siogel. This adsorbent has recently been suggested and tested for adsorptive transformation and storage of low temperature heat. The original data on the water vapour equilibrium and dynamics are compared with those earlier reported for the Fuji silica RD. This database can be used for theoretical analysis, mathematical modeling and evaluation of adsorptive cycles based on the working pair "water – Siogel" and driven by heat from renewable heat sources. Highlights: The aim of this paper was to study the equilibrium and dynamics of water adsorption on silica gel Siogel. Adsorption equilibrium measurements were carried out by the use of a thermo-gravimetric system. Dynamic characterization of a monolayer configuration was carried out with the LTJ method by using three independent set-ups. The original data on the water vapour equilibrium and dynamics are compared with those earlier reported for Fuji silica RD.
