SSZ-13 zeolite

Product Name Name:SSZ-13 zeolite Product Overview Na-Type SSZ-13 Zeolite (Na-SSZ-13, general chemical formula Naₓ[AlₓSi₍₁₋ₓ₎O₂]·nH₂O) is a silicoaluminate zeolite with the CHA framework topology (Chabazite), first reported by Zones in 1985. SSZ-13 features elliptical 8-membered ring (8-MR) main pores with an aperture of approximately 3.8 Å × 3.8 Å, providing excellent molecular sieving and shape-selective catalysis. This material is widely used in NH₃-SCR deNOx, MTO (methanol-to-olefins), CO₂ adsorption, CH₄/N₂ separation, and other reactions and separations. The product covered in this datasheet is in the initial Na⁺ form, with customizable SiO₂/Al₂O₃ ratios in the range of 10–120. It has been fully refined by NH₄⁺ exchange with residual Na₂O ≤ 0.05 wt%, making it ready for direct use as a parent material for ion exchange (Cu²⁺, Fe³⁺, etc.) to produce high-performance deNOx catalysts such as Cu-SSZ-13, or acidic zeolites such as H-SSZ-13.

High Surface Area: BET specific surface area ≥ 500 m²/g, providing abundant active sites for catalytic reactions and gas adsorption. 2. Ultra-Low Residual Sodium: Na₂O content ≤ 0.05 wt%, after deep NH₄⁺ exchange — prevents sintering and metal-site poisoning by Na⁺ in downstream catalysts. 3. Narrow-Distribution Micropores: 8-membered ring main channels (0.38 × 0.38 nm) provide excellent molecular sieving and shape selectivity for small molecules (NH₃, NO, CO₂, CH₃OH, C₂H₄, C₃H₆, etc.). 4. Wide Si/Al Window: SiO₂/Al₂O₃ ratio covering 10–120, suitable for diverse needs such as SCR (high silica for hydrothermal stability) and MTO (high Al for activity). 5. Pure CHA Phase: XRD shows a single CHA topology without obvious impurities such as P1 or GME. 6. Uniform Sub-Micron Particles: Particle size ~ 2 μm with narrow distribution (typical D₅₀ ≈ 2 μm, PSD CV ≤ 30%) — ideal for coating, extrusion, and spray-drying. 7. Excellent Ion-Exchange Capacity: Low Na content enables efficient subsequent exchange with Cu²⁺, Fe³⁺, Mn²⁺, Co²⁺, Ag⁺, etc.; a preferred parent material for high-performance deNOx catalysts such as Cu-SSZ-13. 8. Batch-to-Batch Consistency: Industrial production line ensures tight batch-to-batch variation (≤ 5%) on key indicators (XRD crystallinity, BET, Na content). 9. Green Synthesis: TMAda⁺ template route with template-recovery process; aligned with green chemistry requirements. Application Fields • Diesel / Lean-Burn Gasoline NH₃-SCR deNOx Catalyst (largest commercial use): As the parent material for Cu-SSZ-13 — a core catalyst component for diesel vehicle exhaust treatment under Euro VI / China VI regulations. • Natural Gas Engine / Industrial Boiler Flue Gas deNOx: After Cu²⁺ or Fe³⁺ exchange, used for stationary source NH₃-SCR. • MTO / MTP (Methanol-to-Olefines / Propylene): Na- or H-form SSZ-13 with high Al content for selective synthesis of ethylene and propylene. • CO₂ Adsorption / Carbon Capture: Uniform micropores enable CO₂/N₂ separation from flue gas and CH₄/CO₂ separation from biogas. • CH₄ / N₂ Separation: Molecular sieving for CH₄ enrichment from low-concentration methane or coal-bed methane. • Natural Gas Dehydration / Deacidification: Adsorbs H₂O, H₂S, CO₂ and other polar impurities. • VOCs Adsorption: Selective adsorption of light hydrocarbons and Cl/O-containing VOCs. • Hydrofluorocarbon (HFC) / Refrigerant Adsorption: For refrigerant recovery and separation. • Other Metal Ion-Exchange Research: After Co²⁺, Mn²⁺, Fe³⁺, Ag⁺ exchange, used in CO oxidation, VOC combustion, antimicrobial materials, and related research. • Research Reference Material: Standard sample for zeolite fundamental research, structure–property studies, and SCR reaction mechanism research.
