And structure characteristics of molecular sieves 4a has a crystal surface as the solid skeleton, the internal cavity can have the effect of adsorbed molecules. Cavity between a channel are connected, molecules by the channel. As a result of the cavity clean properties, molecular sieve pore size distribution is very uniform. zeolite adsorbent according to the crystal to selective adsorption of molecules, the size of the internal cavity is adsorbed molecules of a given size and reject material larger molecules.
Zeolite molecular sieve according to its hole or channel system can be divided into the hole, the hole (mesoporous) and double Kong Feishi three categories.
Can be used for the pressure swing adsorption of oxygen enriched air separation.
