5. Zeolite drying, or "zeo-dratation
5.1 Principles of zeolite drying
Zeolites are natural or, more often, synthetically produced minerals with a high affinity for water when dry. Zeolite 4A, for example, has a pore diameter of around 4 Å (1 Å = 10 –10 m), which corresponds to a very high binding energy with the water molecule. This results in very "high" zeolite sorption isotherms at low values of X as shown in figure 9 (water content X dry basis, cf.
