Abstract
Equilibrium moisture content of activated aluminas, active carbons, activated clay and so on was measured at a temperature ranging from 10 to 50°C. The experimental results were shown in Table. Furthermore, the temperature dependence of equilibrium moisture content was discussed.
Results obtained are as follows:
1) The values of equilibrium moisture content are smaller than those of water vapor adsorption, and both curves are parallel as shown in Fig. 2.
2) In both processes for increasing and decreasing humidity, the temperature dependence of the moisture content of activated aluminas and activated clay is illustrated by plot of the equilibrium moisture content as a function of adsorption potential.
3) Plots of We/ρS vs. adsorption potential fall on a curve as shown in Fig. 5. The curve is independent the kinds of materials and of the temperature in the low humidity region in which no capillary condensation takes place in a pore. This fact can be used for estimating the equilibrium moisture content.
