FAQ
What are the main uses of molecular sieves?
- Gas drying: Removes moisture from compressed air, natural gas, and industrial gases (commonly 3A, 4A).
- Purification & separation: CO₂/H₂S removal (13X), oxygen/nitrogen separation (carbon molecular sieve).
- Petrochemicals: Isomerization of alkanes, aromatic separation (5A, Type Y).
- Refrigerant drying: Moisture adsorption in HVAC systems (4A).
- Others: Pharmaceutical desiccation, ethanol dehydration, nuclear wastewater treatment.
How to choose the right molecular sieve?
- Target molecule size: 3Å for water (2.6Å), 4Å for propane (4.3Å), 5Å for n-butane (4.9Å).
- Chemical compatibility: Acidic gases (e.g., H₂S) require acid-resistant sieves.
- Temperature & pressure: High-temperature applications need thermally stable variants.
What’s the difference between molecular sieves, activated alumina, and silica gel?
- Selectivity: Molecular sieves have precise pore sizes; silica gel/alumina have broader distributions.
- Humidity performance: Molecular sieves outperform at low humidity.
- Heat resistance: Sieves withstand >350°C; silica gel degrades above 200°C.
