Zeolite molecular sieves have the structure and characteristics of crystals, the surface is a solid skeleton, and the internal holes have the function of adsorbing molecules. There are pores connected to each other, and molecules pass through the pores channels. Due to the crystalline nature of the pores, the pore size distribution of molecular sieves is very uniform. Molecular sieves selectively adsorb molecules according to the size of the holes in their crystal, that is, they adsorb molecules of a certain size and repel molecules of larger substances, so they are figuratively called "molecular sieves."
The X-type molecular sieve 13X has a much larger pore opening than the A-type. It is mainly used for the purification of raw gas in air separation plants to remove water and carbon dioxide; the drying and desulfurization of LNG, liquefied petroleum gas, and liquid hydrocarbons; and the deep drying of general gases.
13X (APG) special molecular sieve for air separation is a sodium-type aluminosilicate, the pore size of the crystal is 9Å (0.9nm), and it can adsorb any molecule smaller than 9A, so usually it can be used for the drying of general industrial gas and the purification (simultaneous removal of H2O and CO2 and some hydrocarbons) of feed gas in air separation units. It meets the special requirements of the cryogenic air separation industry, improves the adsorption capacity of carbon dioxide and water, and avoids the phenomenon of freezing towers during the air separation process. It has the characteristics of high carbon dioxide adsorption capacity, low regeneration temperature and long service life.

Storage
Prevent the molecular sieves from exposing directly to the damping environment and any absorption of water or organic substance before it's used, otherwise it must be regenerated.
All Chemequip molecular sieves can be regenerated by temperature or pressure swing.
Delivery
For small quantity order < 100kg, 10 days after purchased contract is efficient.
For big quantity order > 500kg, 15 days after purchased contract is efficient.
