FAQ
What is a molecular sieve?
- A molecular sieve is an aluminosilicate material with a uniform microporous structure and fixed pore sizes (e.g., 3Å, 4Å, 5Å). It selectively adsorbs molecules based on size and polarity. Through ion exchange or synthesis processes, it can efficiently separate specific molecules (e.g., water, CO₂, hydrocarbons).
What are the types of molecular sieves?
- By pore size: 3Å (adsorbs water), 4Å (water and small molecules), 5Å (water, CO₂, n-alkanes), 13X (larger molecules like CO₂, H₂S).
- By composition: Zeolite molecular sieves (Type A, X, Y), carbon molecular sieves, aluminophosphate sieves.
- By form: Spherical, pelletized, powdered
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.
