SAPO-34 molecular sieve is a high-performance silicoaluminophosphate material designed for selective adsorption and catalytic applications in industrial processes. Featuring a chabazite (CHA) framework with well-defined micropores, it provides superior efficiency in methanol-to-olefins (MTO) conversion, light olefin production, and hydrocarbon separation. This molecular sieve is widely used in petrochemical refining, fine chemical synthesis, and large-scale catalytic processes, ensuring reliable adsorption and catalytic performance for continuous industrial operations.
Product Overview
SAPO-34 is a silica-alumina-phosphate molecular sieve with a three-dimensional cross-linked pore structure and moderate acidity. Its unique pore structure and medium-strength acidity make it highly effective in various catalytic and separation processes. It is widely used in the production of light olefins, automobile exhaust purification, gas separation, and functional materials. By adjusting synthesis conditions and silicon content, SAPO-34 can be tailored to have different acidity and topological structures, expanding its range of applications.
Key Features
- Three-Dimensional Cross-Linked Pores: With eight-membered ring pore openings, SAPO-34 is ideal for selective molecular sieving of small molecules, especially beneficial for the selective synthesis of light olefins.
- Moderate Acidity: Provides suitable acidic catalytic centers for the conversion of light olefins, improving the yield and selectivity of target products.
- Good Thermal and Hydrothermal Stability: Maintains stability in high-temperature and high-humidity environments, making it suitable for harsh industrial reaction conditions.
- Excellent Molecular Sieving Performance: Through the combination of pore size and acidic center selectivity, SAPO-34 demonstrates outstanding catalytic performance in olefin cracking and conversion processes.
Applications
- Low Carbon Conversion to Light Olefins: Primarily used in the methanol-to-olefins (MTO) reaction and chloromethane-to-light olefins processes. SAPO-34 offers high selectivity for ethylene and propylene, making it widely used in petrochemical and olefin production.
