SSZ-13 molecular sieve is a high-performance zeolite with a chabazite (CHA) framework, specifically designed for selective adsorption and catalytic applications in industrial processes. Featuring a well-defined microporous structure and controlled acidity, it provides superior efficiency in hydrocarbon conversion, selective gas separation, and catalytic NOx reduction. This molecular sieve is widely used in petrochemical refining, emission control technologies, and large-scale selective catalytic reduction (SCR) processes, ensuring reliable adsorption and catalytic performance for continuous industrial operations.
Product Overview
SSZ-13 is a microporous molecular sieve with a chabazite (CHA) structure, featuring three-dimensional cross-linked pores and an ellipsoidal cage structure. Its pore size is 0.38 nm × 0.38 nm, and the specific surface area can reach 700 m²/g. With its ordered pore structure, excellent hydrothermal stability, and rich surface protonic acidity centers, SSZ-13 shows outstanding performance in catalysis, gas separation, and environmental protection. By adjusting synthesis conditions and metal ion loading, its catalytic activity and selectivity can be further enhanced.
Key Features
- Ordered Pore Structure: Features eight-membered ring structures and cross-linked pores, making it suitable for molecular sieving and catalytic reactions.
- Excellent Hydrothermal Stability: Maintains stable performance even in high-temperature and humid environments.
- Good Acidity Centers: Contains a large number of surface protonic acidity centers, making it ideal for catalytic reactions.
- Separation Performance: Exhibits excellent selectivity in separating gas molecules, particularly for small gas molecules.
Applications
- Automotive Exhaust NOx Removal: As a carrier, SSZ-13, when loaded with metal ions, effectively catalyzes the selective reduction (SCR) of NOx, especially suitable for NOx treatment in diesel vehicles.
- Methanol to Olefins (MTO): Due to its microporous structure, SSZ-13 shows high selectivity for light olefins in the methanol-to-olefins reaction, making it ideal for low-carbon olefin production.
- Gas Separation: SSZ-13 membranes effectively separate gases such as CO2/CH4, H2/CH4, CO2/N2, and H2/n-C4H10, widely used in gas separation and purification processes.
- CO2 Adsorption and Separation: Its pore structure and adsorption properties make SSZ-13 particularly suitable for CO2 adsorption and separation, with significant applications in gas separation and environmental protection.
