Product Introduction
13X molecular sieve is an alkaline metal silica aluminumate.The effective aperture of 13X molecular sieve is 10Å. Its honeycomb-like structure creates a sieving effect through micro pores, enabling it to selectively adsorb molecules with diameters less than 10 Å. It can be used for catalyst carrier,water and carbon dioxide co-adsorption,water and hydrogen sulfide gas co-adsorption.Nowadays it is mainly used in medicine and air compression system drying.

Main Application of 13X molecular sieve
1.It is used to deeply remove water vapor, carbon dioxide and acetylene and other impurities from the raw gas, preventing the low-temperature equipment from freezing the tower.
2.It is used for drying and desulfurization of natural gas and liquefied petroleum gas, selectively adsorbing hydrogen sulfide and other organic sulfides.
3.In industrial waste gas treatment, it effectively adsorbs volatile organic compounds (VOCs) such as toluene, and is suitable for industries such as spraying and printing.
4. It can also be used as a catalyst carrier, it is used in reactions such as selective reduction of NOx (SCR), and its microporous structure helps to disperse the active components.
5.It can be used for carbon dioxide capture, for example, for adsorbing CO₂ in radiocarbon (14C) analysis.
Product Package and Storage
Packaging: Steel drum / paper drum / aluminum foil bag or according to customer's request.
Storage: Avoid damping and any adsorption of water or organic substance before use. Otherwise it must be regenerated.
FAQ
1.What is 13X molecular sieve used for in an air separation unit?
Answer: Before air separation (oxygen/nitrogen production), the raw air needs to be deeply purified. 13X molecular sieve is used for:
Adsorbing water (H₂O)
Adsorbing carbon dioxide (CO₂)
Adsorbing hydrocarbons such as acetylene (C₂H₂)
Preventing these impurities from freezing and blocking in the low-temperature distillation tower (a "frozen tower"), ensuring the safe and efficient operation of the equipment.
2.Do 13X molecular sieves have different forms? How to choose?
Spherical (Φ1.6–2.5mm, Φ3–5mm): Low pressure drop, suitable for fixed beds
Strip-shaped (Φ1.6×3–10mm): High strength, resistant to wear
