13x Molecular Sieve Regeneration Process

October 17, 2022

What is Molecular Sieve Regeneration?

Molecular sieve regeneration allows the wet or deactivated zeolite to restore to its original working capacity without damaging the zeolite or physical properties. It is a crucial step because it determines the performance and the overall operational cost of molecular sieves. Molecular sieve regeneration involves heating and purging with carrier gas to remove the adsorbate from the molecular sieve bed. To raise the temperature of the adsorbate, the adsorbent, and the container, adequate heat must be applied. Then the liquid can be vaporized to offset the heat from the surface of the wetted molecular sieve.


What is a 13x Molecular Sieve?

13X molecular sieve is sodium form X type crystal structure and a kind of alkali metal aluminum silicate. It is available in powders, granules, and beads.

Its pore size is larger than 3A, 4A, and 5A molecular sieves which are about 10A°. 13x zeolite molecular sieve can absorb molecules less than 9 angstroms in diameter. Zeolite molecular sieve 13X is mainly used for industrial natural gas drying, to absorb water and moisture in these gases including CO2, H2S, O2, H2, NH3, etc., 13X molecular sieves are also used for mercaptan removal, carrying catalysts, air compressor systems, solvent (liquid) purification.
