Zeolite knowledge: uses and zeolite molecular sieves with unique properties

Feature uses zeolite 13x molecular sieves it is widely used in petrochemical, gas, refrigeration, food and other fields. 
The main applications are: 
1, the drying activated alumina and liquids; 
2, the purification of gases and liquids; 
3, separating gas and liquid; 
4, hydrocracking, catalytic cracking and isomerization catalyst; 
5, detergent additives and water softener
Zeolite has unique properties:
1, water, gas and liquid reversible adsorption 2, 3 cation exchange properties, pore zeolite has a very high internal surface area suitable for use as a molecular sieve for this depth drying, selective adsorption and catalysis, molecular sieves and other adsorbents Comparison prominent features: 
1, 2 very high adsorption capacity, selective adsorption and separation of 3, 4 catalytic properties, ion exchange characteristics

Desiccant applied to prevent the equipment, instruments, electrical equipment, pharmaceuticals, food, textiles and other various packaging items damp, at sea en route desiccant is also widely used, because the goods during transport often large and moisture deterioration due to zeolite 13x temperature, dry agents can effectively dehumidification moisture, so that the quality of the goods are protected.
A desiccant to absorb moisture from the atmosphere, in addition to a liquid, its drying principle is physically adsorbed water molecules in the structure itself, or the absorption of water molecules activated zeolite powder 5a  through chemical means, and changes its chemical structure, into another substances.
Common desiccants are lime desiccant chemisorption, magnesium chloride, calcium chloride, phosphorous pentoxide, or soda lime, silicic acid, which are chemically absorb water molecules and change its chemical structure into another material.
