Conclusions
-
1.
The maximum rehydration energies of mesolite and thomsonite after their dehydration at 220 ± 5 and 230 ± 5°C are 310 ± 15 and 300 ± 15 J/g, respectively, while the integral molar heats of water vapor adsorption are 86 ± 5 and 93 ± 5 kJ/mole, respectively.
-
2.
The dependence of the extent of rehydration of thomsonite at 25°C on the pumping temperature (4 h) traverses a minimum at 160 ± 5°C and maximum at 220 ± 20°C.
