Non-adsorbable component influence on the dynamics of water sorption on the composite adsorbent

Abstract

The analysis of the experimental data on water adsorption in the presence of a non-adsorbable component on the composite adsorbent “silica gel impregnated with calcium chloride” for different partial pressures of water and air was performed. It was established that the mass-transfer mechanism inside a grain is Knudsen diffusion; it was shown that in the system there is formed a dynamic structure with the increased concentration of non-adsorbable component close to the external surface of grain, causing externally diffusive resistance; the coefficient of heat exchange between grain and gas phase was defined.
