AB Hygroscopic salts supported by a mesoporous matrix for improved mass transport are promising sorbents for water-based sorption cycles that operate at low pressure. In this study, loose grain composites of CaCl<sub>2</sub> supported by mesoporous silica gels with four distinct pore size distributions were prepared and compared with AQSOA FAM-Z02, a silicoaluminophosphate zeolite desiccant. A salt in silica gel sorbent consolidated with graphite flakes and binder was also analyzed. The sorbents were evaluated with a volumetric nitrogen physisorption porosimeter and thermogravimetric water vapor sorption analyzer. The hygroscopic salt filled 56&minus;60&#37; of the open pore volume of the mesoporous silica gel supports. Water uptake capacity of the CaCl<sub>2</sub>/silica gel sorbent was up to 0.33 g per gram of dry sorbent at 12 mbar and 35&#176;C, and sample performance was consistent through 200 wetting&minus;drying cycles.
