Description

Molecular Sieve CAS NO 1344-00-9 is a highly porous, crystalline aluminosilicate material engineered for selective adsorption based on molecular size and polarity. Its exceptional value lies in its ability to dry gases and liquids to extremely low dew points, separate mixtures, and purify process streams with high efficiency and capacity. This product is essential for industries requiring stringent moisture control and separation, including petrochemical refining, natural gas processing, industrial air drying, and the production of insulated glass windows.

Application

• Gas Drying: Deep dehydration of natural gas, air, synthesis gas (syngas), and refrigerant gases to prevent corrosion and hydrate formation.
• Liquid Drying: Removal of trace water from organic solvents, ethanol, liquid hydrocarbons, and insulating oils in transformer applications.
• Separation Processes: Separation of normal paraffins from iso-paraffins and aromatics in the petroleum industry, and oxygen from air via pressure swing adsorption (PSA).
• Insulating Glass: Used as a desiccant in the spacer of double-pane windows to adsorb residual moisture and prevent fogging.
• Catalyst Support & Carrier: Provides a stable, high-surface-area matrix for various catalysts in chemical reactions.
• Environmental Protection: Adsorption of volatile organic compounds (VOCs), CO2, and other impurities from industrial waste streams.
• Refrigeration Systems: Protects systems by adsorbing moisture and acids in refrigerant circuits.
• Packaging: Used in desiccant packets to control humidity and extend the shelf life of pharmaceuticals, electronics, and food products.

Quality Control

Our molecular sieve products are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Key parameters such as adsorption capacity, crush strength, particle size distribution, and bulk density are rigorously tested. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the product must be stored in a cool, dry, and well-ventilated area. Keep the container tightly sealed when not in use to prevent premature adsorption of atmospheric moisture, which reduces its effective capacity. Store away from strong acids and strong oxidizing agents. Recommended storage temperature is 15-25°C.
