Introduction of spherical 3A molecular sieve products
3A molecular sieve is an alkali metal aluminosilicate, which is also known as 3A zeolite molecular sieve. 3A type molecular sieve refers to: A type molecular sieve containing Na+ is denoted as Na-A, if Na+ is replaced by K+, the pore size is about 3A molecular sieve; 3A molecular sieve is mainly used for adsorbing water, and does not adsorb any molecule with a diameter greater than 3A, it is Desiccant necessary for deep drying, refining and polymerization of gas and liquid phases in petroleum and chemical industries.
Chemical formula: 2/3K2O·1/3Na2O·Al2O3·2SiO2·9/2H2O
Si-Al ratio: SiO2/Al2O3≈2
Effective Pore Size: About 3Å
Features of 3A type molecular sieve desiccant:
3A molecular sieve has fast adsorption speed, strong crushing strength and anti-pollution ability, which increases the utilization efficiency of molecular sieve and prolongs the service life of molecular sieve.
1. 3A molecular sieve removes water: it depends on the pressure, temperature and water content of the gas. The drying gas at 200～350℃ is 0.3～0.5Kg/square centimeter, passes through the molecular sieve bed for 3～4 hours, and the outlet temperature is 110～180℃ to be cooled.
2. 3A molecular sieve removal of organic matter: replace organic matter with water vapor, and then remove water
Scope of application of adsorbent 3A molecular sieve:
3A molecular sieve is mainly used in architectural glass industry, gas refining and purification and petrochemical industry
1.3A Molecular sieve drying of various liquids (such as ethanol)
2. Air drying
3. Drying of refrigerant
4.3A molecular sieve drying of natural gas and methane gas
5. Drying of unsaturated hydrocarbons and cracked gas, ethylene, acetylene, propylene, butadiene, drying of petroleum cracked gas and olefins
Molecular sieve manufacturers 3A type molecular sieve technical indicators:
implementation standard: GB/T 10504-2008
Molecular sieve manufacturers 3A molecular sieve packaging and storage:
3A molecular sieve Storage: Indoors with humidity not greater than 90 degrees: avoid water, acid, alkali, and isolated air for storage.
3A molecular sieve packaging: 30Kg sealed steel drum, 150Kg sealed steel drum, 130Kg sealed steel drum (strip).
product description:
The pore size of 3A molecular sieve is 3A. It is mainly used for adsorbing water, and does not adsorb any molecules with a diameter larger than 3A. According to the characteristics of industrial applications, the molecular sieves we produce by Gloria have faster adsorption speed, more regeneration times, high The crushing strength and anti-pollution ability increase the utilization efficiency of molecular sieves and prolong the service life of molecular sieves.
Precautions:
Molecular sieves should be prevented from adsorbing water, organic gases or liquids before use, otherwise, they should be regenerated.
