Introduction

Molecular sieve also called zeolite, is a crystalline aluminum silicate. Its crystal structure has neat and uniform channel, aperture around a molecular level, molecular sieve only allows smaller diameter than its aperture into it, so it can sieve molecules according to their size in the mixture, so it called molecular sieve. According to molecular sieve aperture size, there are 3A, 4A, 5A, 10X, 13X. 4A molecular sieve is Na-A molecular sieve, aperture 0.4nm; if Na replaced by K, aperture 0.3nm, is 3A molecular sieve; if over 1/3 Na replaced by Ca2+, aperture 0.5nm, is 5A molecular sieve.

3A molecular sieve, also called Kalium A molecular sieve, is Kalium ion alkali metal alumino-silicate compound. Its effective pore diameter is 3A (0.3nm), it can selectively adsorb those molecules in fluid which dynamic diameter is less than 0.3nm (such as water molecules, ammonia molecules), lets molecule dynamic diameter more than 0.3nm go through molecular sieve layer bed, and then achieve the aim of fluid mixture. 3A molecular sieve has small aperture, while adsorbs water molecules it can reject all other molecules, thus effectively avoid “total adsorption” phenomena. 3A molecular sieve is a kind of excellent desiccant used for adsorbing water mainly.

Application

Drying and purification of oil cracking gas; C2 and C3 fraction drying; ethylene, propylene, butylene, butadiene, pentane drying and purification; dehydration and purification of raw material of methane, ethane and propane; purification of liquid carbon dioxide; dissolved acetylene drying; water, air, gases, polar liquids (such as methanol, ethanol) and natural gas drying and purification; refrigerator drying; catalyst support; etc. 3A molecular sieve are widely used in petroleum refining, petrochemical, chemical industry, metallurgy, electronics, defense, etc., while in pharmaceuticals, light industry, agriculture, environmental protection and many other aspects, has increasingly been applied.
