Product Description

13X Molecular Sieve
13X Molecular Sieve Product Description
The 13X Molecular Sieve is the sodium form of the Type X crystal structure, representing a significant advancement over standard Type A zeolites. With a much larger effective pore opening of 10 angstroms (1.0 nm), it is capable of adsorbing molecules with larger kinetic diameters. Furthermore, its unique internal cavity structure provides the highest theoretical adsorption capacity for water, carbon dioxide, and hydrogen sulfide among common adsorbents, making it an indispensable material for deep purification in heavy industries.
Product Highlights
Massive Adsorption Capacity

Boasts a larger pore opening and higher void fraction, delivering exceptional dynamic and static adsorption capacity for H2O and CO2.

Deep Air Purification

Specifically engineered for cryogenic air separation units (ASU) to deeply remove moisture and carbon dioxide simultaneously, preventing ice formation and equipment blockages.

Excellent Mass Transfer Rate

The unique X-type crystal structure facilitates exceptionally rapid adsorption and desorption kinetics, enhancing overall cycle efficiency.

Superior Mechanical Strength

Advanced manufacturing ensures high crushing strength, preventing bed collapse and minimizing dust generation in high-flow, high-pressure reactors.

Exceptional Stability

Maintains robust structural integrity and consistent adsorption performance over thousands of continuous thermal regeneration cycles.

Typical Applications
  • Pre-purification of air (simultaneous removal of H2O and CO2) in Cryogenic Air Separation Units (ASU).
  • Desulfurization (removal of H2S and mercaptans) and sweetening of natural gas and liquid hydrocarbons.
  • Medical and industrial oxygen generation via Pressure Swing Adsorption (PSA) and VPSA systems.

Frequently Asked Questions
What is the pore size of a 13X molecular sieve?

The 13X molecular sieve has an effective pore opening diameter of roughly 10 Angstroms (1.0 nm), enabling it to adsorb any molecule with a kinetic diameter under 10 Å.

How does 13X differ from 4A molecular sieves?

While 4A molecular sieves possess a ~4 Å pore opening (Type A crystal), 13X features a ~10 Å pore opening (Type X crystal), allowing 13X to capture much larger compounds such as aromatic hydrocarbons, branched molecules, and significant amounts of CO2 alongside moisture.

Can 13X molecular sieve be regenerated for reuse?

Yes, 13X molecular sieves can be regenerated through thermal swing adsorption (TSA) by heating the bed to 200°C–315°C, or via pressure reduction in Pressure Swing Adsorption (PSA) processes.

Why is 13X essential for Cryogenic Air Separation Units (ASU)?

In cryogenic air separation, trace amounts of water and carbon dioxide will freeze at ultra-low operating temperatures and clog the heat exchangers. 13X simultaneously and deeply adsorbs both H2O and CO2, preventing operational blockages.

Which shape should I choose: spheres or pellets?

Spherical beads typically offer lower attrition rates and more uniform bed packing, which minimizes dusting and pressure drop variations. Pellets/extrudates are frequently chosen when dynamic mass transfer and specific flow geometries are needed.
