13XAPG Molecular Sieve

‌13X-APG molecular sieve is a sodium X-type aluminosilicate crystal with a pore size of 10A, which can adsorb molecules with a critical diameter less than 10A. Its main component is aluminosilicate, and its chemical formula is Na86[(AlO2)86(SiO2)106]·XH2O. 13X-APG molecular sieve has a high carbon dioxide adsorption capacity, and can also adsorb trace moisture, acetylene and other hydrocarbons in the air.

Application field:

 

13X-APG molecular sieve is widely used in the cryogenic air separation industry, especially in the cryogenic air separation purification system to remove H2O and CO2 to avoid the freezing tower phenomenon in the cryogenic process. In addition, it is also used for general gas drying, drying of air compression systems and the medical field. In industry, 13X-APG molecular sieve is often used to remove H2O and CO2 from the air, and is suitable for cryogenic air separation devices of various sizes.

 

Regeneration method:

 

The regeneration of 13X-APG molecular sieve can be carried out by increasing the temperature, purging or vacuuming. The specific steps include passing dry gas through a molecular sieve bed at a pressure of 0.3 to 0.5 kg/cm2 at 200 to 350°C for 3 to 4 hours to make the outlet temperature reach 110 to 180°C, and then cooling.
