The 3A molecular sieve is mainly used to adsorb water, and does not adsorb any molecules with a diameter greater than 3A. According to industrial application characteristics, the molecular sieve we produce has faster adsorption speed, more regeneration times, higher crushing strength and anti-pollution It can improve the utilization efficiency of molecular sieve and prolong the service life of molecular sieve. It is the first choice desiccant necessary for deep drying, refining and polymerization of gas and liquid phases in petroleum and chemical industries.

Chemical formula: 2/3K₂O·1/3Na2₂O·AI₂O₃·2SiO₂·.9/2H₂O
Silicon to aluminum ratio: SiO₂/Al₂O₃≈2
Effective aperture: about 3A

Application: Mainly used for the drying of petroleum cracked gas, enyne, refinery gas and oil field gas. It is an industrial desiccant for chemical industry, medicine, insulating glass and so on.

Technical index:

Residual water content	≤%wt	1.5	1.5	1.5	1.5

regeneration:
1. Dehydration: It depends on the pressure, temperature and water content of the regeneration gas. Under normal circumstances, 200-350 ℃ dry gas under the pressure of 0.3-0.5kg / cm2, through the molecular sieve bed for 3-4 hours, the outlet temperature to 110-180 ℃, cooling.
2. Deorganization: replace organics with steam, then remove moisture.

Save:
Room temperature, relative humidity is not more than 90%; should not be directly exposed to the air; avoid water, acid, alkali.

Packing: 25KG cardboard drum or bag.

Specific according to customer requirements. A

Precautions:

Do not open the package before use to avoid moisture and affect the adsorption effect.
