The main component of 13X molecular sieve is aluminosilicate, forming a sodium X molecular sieve with a pore size of 10A, which is an X-type crystal structure.Is gas, chemical,
The best desiccant in the air separation industry.Where the technical indicators can be adsorbed on 3A, 4A, 5A molecular sieve, 13X type can be adsorbed.
Chemical formula:Na2O·AL2O3·(2.8±0.2)Sio2·(6-7)H2O
Silicon to aluminum ratio:SiO2/Al2O3≈2.6-3.0
Effective aperture: about 10A

Uses:
Industrial gas drying and purification can also be used as a carrier.
Purification of the raw material gas of the air separation unit (removing H2O and CO2 simultaneously).
Desulfurization of liquid hydrocarbons and natural petroleum gas (removal of hydrogen sulfide and mercaptans).
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.
Storage: 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.
Note: Avoid direct molecular sieve exposure to air.
