Product Description

Molecular Sieve 5a As Professional Desulfurizing Agent




Zeolite 5a molecular sieve is a synthetic zeolite of the A-type crystal structure with a pore opening of 5 angstroms (0.5 nm), also name Calcium zeolite molecular sieve, can absorb any molecule smaller than this pore diameter. Mainly used in the separation of normal and heterogeneous hydrocarbon, PSA(Pressure Swing Adsorption), Co-adsorption of water and carbon dioxide. Highly selective adsorption, Faster adsorption rate, Particularly suitable for pressure swing adsorption, can be adapted to various sizes of gas pressure swing adsorption device for oxygen generating, hydrogen manufacturing, CO2 producing, etc. It is the best choice in pressure swing adsorption industry.


Addition to the effect of 3a and 4a molecular sieve, the 5a molecular sieve can also absorb C3-C4 N-alkanes, ethyl chloride, ethyl bromide, butanol, etc.


Chemical Formula: Ca4,5 [(AlO2)12(SiO2)12] · nH2O

1. Specialized desulfurization deodorant
2. Dehydration and purification of inert gas
3. Removal of water, carbon dioxide, and hydrocarbons from feed gas in air pre-purification units
4. PSA separation for Iso/normal paraffin (n-C4∼n-C6 mixtures)
5. Purification of air, oxygen, nitrogen, hydrogen and synthesis gases from mixed gas streams
6. Dehydration and purification of LPG (Liquefied Petroleum Gas), ammonia cracked gas and other industrial gases or liquids
7. Removal of H2S(hydrogen sulfide), COS and light thiol from natural gas and LPG (Liquefied Petroleum Gas)





Molecular sieve 5a synthetic aluminum silicate can’t be exposed in the open air and should be stored in dry condition with the air-proof package.
mol sieve 5a synthetic aluminum silicate can be regenerated after a certain period of adsorption.

The appropriate regenerated temperature would be better below 350°C.
