Abstract
Because of decreasing differential molar heats of sorption from LiLSX (100-70Â kJ/mol) to SAPO-34 (90-65Â kJ/mol) and to supported CaCl2 (70-50Â kJ/mol) the isotherms are shifted towards higher equilibrium pressure by about three orders of magnitude. The energy densities at 313Â K and up to 20Â mbar vapor pressure decrease in the same order from 1184 to 997 and 871Â kJ/kg adsorbens. The average temperatures for the desorption of the water decreases as well from >450 to <400Â K which classifies the silicoaluminophosphate between the common zeolites and the salt hydrates with regard to the properties as thermochemical storage material.
