13X Molecular Sieve
Molecular Sieve 13X is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals.The pore size 13X molecular sieve is about 10 Å . It can adsorb any molecular smaller than 10 Å , mainly used as catalyze carrier, co-adsorption of CO2 and H2O, H2O and H2S, as desiccant for medical and air compressor system, and can also be adjusted to fit other various applications.
Typical Chemical Formula
Na2O . Al2O3 . (2.8±0.2) SiO2 . (6~7)H2O
SiO2 : Al2O3 ≈2.6-3.0

Applications:
Air refining (removing CO2 and H2O)
Removal of mercaptans and hydrogen sulphide from natural gas
Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.)
Oxygen PSA (Pressure Swing Adsorption) process
special double glass (removing solvent and grease)
Regeneration
Molecular Sieve Type 13X can be regenerated by evacuating or purging, usually at elevated temperatures. The purge gas temperature must be sufficiently high to bring the molecular sieve to a level of 250°C – 350°C.
