zeolite molecular sieves

Zeolite adsorption has two characteristics: (1) the center of the polarity on the surface of a Lewis strong; (2) the zeolite cages or channels in small size, which makes the strong molecular sieve siliporite gravitational field. Therefore, the adsorption capacity of the adsorbate molecules is much more than other types of adsorbent. Even adsorbate partial pressure (or concentration) is low, the adsorption capacity is still considerable. Zeolite adsorption separation not only the size and shape of 4a zeolite powder the adsorbate molecules, but also on its polarity, and therefore, the zeolite molecular sieves can also be used to separate substances of similar size.
