Description

Zeolites are a class of microporous, aluminosilicate minerals widely recognized for their exceptional adsorption, ion-exchange, and catalytic properties. Their unique crystalline structure, featuring uniform pores and channels, makes them indispensable in industrial processes requiring molecular sieving and purification. This product is essential for manufacturers and processors in sectors such as petrochemical refining, environmental remediation, detergents, and agriculture, where selective separation and chemical stability are paramount.

Application

• Catalysis & Petrochemicals: As a solid acid catalyst in fluid catalytic cracking (FCC) and hydrocracking to produce high-octane gasoline and other fuels.
• Adsorption & Separation: For drying and purification of natural gas, air, and industrial streams; removal of volatile organic compounds (VOCs), CO2, and sulfur compounds.
• Detergent Builders: As a phosphate substitute in laundry and dishwasher detergents for water softening through ion exchange of calcium and magnesium ions.
• Environmental Remediation: In wastewater treatment and soil remediation to capture heavy metals, ammonium ions, and radioactive isotopes.
• Agriculture & Animal Feed: As a feed additive to improve nutrient absorption, reduce ammonia levels, and act as an anti-caking agent.
• Gas Separation & Storage: For nitrogen generation from air (PSA systems) and research into hydrogen storage.
• Construction: As an additive in cement and concrete to improve strength and durability.
• Consumer Products: In odor control applications for cat litter, refrigerators, and shoes.

Quality Control

Our zeolites are manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Quality parameters such as pore size distribution, ion-exchange capacity, adsorption kinetics, and chemical composition are rigorously tested. Certificates of Analysis (COA) detailing specific grade specifications are provided with each shipment to guarantee compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place with minimal exposure to ambient humidity. For long-term storage, keep the container sealed under a dry, inert atmosphere such as nitrogen to maintain optimal adsorption capacity. Recommended storage temperature is between 15°C and 25°C.
