Selective water sorbents for multiple applications. 12. Water sorption equilibrium at elevate temperature

In this communication we present the experimental data on water sorption equilibrium for SWS-1L (CaCl2 in mesoporous silica) measured at an elevated temperature of 150° to 260°C and the corresponding vapor pressure PH2O of 1.1 to 9.2 bar. A comparison of these data with those obtained at lower T (30-150 °C) and PH2O (8-130 mbar) is made. All experimental data appear to fall on the same temperature-independent curve «water sorption vs. relative vapor pressure» which indicates a universal mechanism of water sorption over the whole T-P range.
