Product Overview:
4A Molecular Sieve is a highly effective synthetic zeolite adsorbent designed for dehydration, purification, and separation processes in industries such as petrochemicals, natural gas, refrigeration, and pharmaceuticals. With a uniform pore size of 4 angstroms (0.4 nm), it selectively adsorbs water and small molecules while excluding larger compounds, ensuring optimal performance in drying and purification applications. Its high adsorption capacity, rapid kinetics, and thermal stability make it ideal for both industrial and laboratory use.
Key Features:
Material Excellence:
- High Adsorption Capacity: Efficiently removes water and other small polar molecules (e.g., CO₂, H₂S) from gases and liquids.
- Thermal Stability: Regenerable at temperatures up to 250–350°C, ensuring long-term usability.
- Chemical Resistance: Inert to most hydrocarbons, alcohols, and non-polar solvents, making it suitable for harsh environments.
Structural Design:
- Uniform Pore Structure: Precisely sized 4Å pores selectively adsorb molecules smaller than 4 angstroms (e.g., H₂O, NH₃).
- High Surface Area: Provides extensive active sites for adsorption, enhancing efficiency.
- Bead/Pellet Forms: Available in 1.5–3.0 mm beads or 1/16”–1/8” pellets for optimal flow dynamics in packed beds.
Performance Benefits:
- Fast Adsorption Kinetics: Rapidly removes moisture, reducing downtime in drying processes.
- Regenerability: Can be reused multiple times through thermal or pressure-swing regeneration.
- Low Attrition Rate: Maintains structural integrity under mechanical stress, minimizing dust formation.
Versatility:
- Broad Applications: Used in drying natural gas, solvents, refrigerants (e.g., R-134a), and insulating glass units.
- Customizable Forms: Tailored mesh sizes and binder-free options for specialized processes.
