Zeolite 13X Molecular Sieve PelletsDescription:
Zeolite 13X is a synthetic crystalline aluminosilicate with a pore size of about 10 Å (angstroms). It is the sodium form of the Type X crystal structure and is supplied in pellet / bead form for industrial use. Compared to Zeolite 3A, 4A, and 5A, it has a larger pore size, enabling it to adsorb molecules with a kinetic diameter less than 10 Å.
Used in Pressure Swing Adsorption (PSA) plants for oxygen generation by selectively adsorbing nitrogen, CO₂, and moisture, allowing oxygen to pass through.
Industrial, medical, and portable oxygen concentrators rely on Zeolite 13X pellets.
Removes H₂O, CO₂, SO₂, and hydrocarbons from industrial gases.
Applied in natural gas processing to dry and purify methane streams.
Purification of hydrogen, carbon monoxide, nitrogen, and argon.
Removes CO₂ in biogas upgrading, syngas purification, and air conditioning systems.
Critical for protecting cryogenic air separation plants from CO₂ freezing.
Applied in the drying and purification of feedstocks (LPG, cracked gas, reformer gas).
Removes acidic gases to prevent catalyst poisoning in downstream petrochemical processes.
Used in flue gas treatment to capture CO₂.
Helps in VOC (volatile organic compound) adsorption from industrial emissions.
Plays a role in renewable energy systems such as biogas purification and carbon capture technologies.
Removes water, CO₂, and other impurities from refrigerants and air-conditioning gases.
Prevents ice formation and corrosion in cooling systems.
Drying of compressed air and industrial solvents.
Dehydration of ethanol and other solvents for pharmaceutical and chemical industries.
High adsorption capacity for CO₂, H₂O, and H₂S.
Regenerable by heating or pressure reduction.
Uniform pellet form ensures low pressure drop in adsorption columns.
Stable performance across multiple adsorption–desorption cycles.
✅ In summary:
Zeolite 13X Molecular Sieve Pellets are primarily used in oxygen concentrators, gas drying, CO₂ removal, air separation, petrochemicals, refrigerant drying, and environmental applications like CO₂ capture and VOC control.
