Product Description

3a Molecular Sieve Remove The Impurity Of Cyclohexane From Normal Hexane


Product Description


3A molecular sieve has aperture,it can adsorb water but don’t adsorb any molecular whose diameter more than 3Å.3A molecular sieve has advantages of quick adsorption,good regeneration capacity,good crush strength and anti-pollution capacity,that increase 3A molecular sieve service efficiency and working life.It’s necessary desiccant for deeply drying, purification and polymerization of gas&liquid in petroleum and chemical industry.

Main uses


1. Drying of unsaturated hydrocarbon,cracked gas,ethylene,acetylene,propylene and butadiene.


2. Drying of natural gas to produce minimization COS natural gas or adsorb carbohydrate.


3. Drying of highly polar compounds,such as methanol and ethanol.


4. Drying for Insulating glass containers filled by air or gases.


5. Dehydration of refrigerant.




1. The product cannot be exposed in the open air and should be stored in dry condition with air-proof package.

2. The product should be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°C.
