concentration in the adsorbent. As shown in Eq. 2, the smaller the size of the adsorbent, the faster the
diffusion rate in the crystal. However, an extremely small adsorbent will hinder the intercrystalline diffusion
of water vapor. Intercrystalline diffusion (D ) can be described by the following equation :
