99% Purity Molecular Sieve 5A 4×8 Mesh Beads

99% Purity Molecular Sieve 5A 4×8 Mesh Beads
Product introduction
 
Xuefeng 5A Molecular Sieve for Hydrogen Purification has a pore size of 5A and can adsorb any molecule with a pore size smaller than 5A. It is generally called a calcium molecular sieve. It has the functions of 3A molecular sieve and 4A molecular sieve. 5A molecular sieves have high adsorption and fast adsorption speed, and are especially suitable for pressure swing adsorption. They can be used for various pressure swing adsorption devices such as oxygen, hydrogen, and carbon dioxide. Adsorbent Porosity 5A Molecular Sieve for Hydrogen Purification can also adsorb C3-C4 n-alkanes, ethyl chloride, bromoethane, butanol, etc. This is a height that 4A molecular sieves cannot reach.
 
Xuefeng 5A Molecular Sieve for Hydrogen Purification can absorb up to 22% of their body weight. Its adsorption principle is similar to that of chromatography, except that the molecular composition of the substance is not changed.
 
Molecular formula: 0.70CaO·0.30Na2O·Al2O3·2.0SiO2·4.5H2O

Scope of application
This kind of sieve absorbs substances at the molecular level. It can absorb up to 22% of its body weight. The adsorption principle is similar to that of chromatography, except that the molecular composition of the substance is not changed.
1. Natural gas drying, desulfurization, and carbon dioxide removal;
2. Separation of nitrogen and oxygen, separation of nitrogen and hydrogen to produce oxygen, nitrogen and hydrogen;
3. Petroleum dewaxing, separation of normal hydrocarbons from branched hydrocarbons and cyclic hydrocarbons.
 
Store
Storage: Room temperature, relative humidity not more than 90%; not directly exposed to the air; avoid water, acid and alkali.
Packing: cardboard drum or carton packaging.
Note: Avoid direct exposure of molecular sieve to air.

Regeneration
1. Removal of water: it depends on the pressure, temperature and water content of the regeneration gas. Under normal circumstances, the dry gas at 200~350℃ will pass through the molecular sieve bed for 3~4 hours under the pressure of 0.3~0.5kg/cm to bring the outlet temperature to 110~180℃ and cool.
2. Removal of organic matter: replace organic matter with water vapor, and then remove water.
 
 
Package
Packed in iron drums, (according to the product model) net weight 125kg, 135kg, 140kg, or according to user needs.
