SAPO-34 Technical Data Sheet
This technical data sheet covers standard specification ranges for SAPO-34 silicoaluminophosphate powder in spray-dried microsphere and powder forms. Custom Si content, particle size, and binder formulation available on request.
Typical Specifications
| Parameter | Typical Range | Test Method |
|---|---|---|
| Si content in framework | 5-15 mol% | XRF or ICP-OES |
| (Si+Al+P)/O stoichiometry | Confirmed CHA SAPO | XRF |
| BET surface area | 500-650 m²/g | N₂ adsorption, BET method |
| Pore size | ~3.8 Å | 8-MR CHA windows |
| Particle size (D50) | 0.5-5 μm | Laser diffraction |
| Loss on Ignition | ≤8 wt% | 600 °C, 3h (template removal) |
| XRD crystallinity | ≥90% | vs CHA reference standard |
| Framework | CHA | XRD confirmation |
Available Grades
- SAPO-34-S5 (Si 5-8 mol%): maximum ethylene selectivity
- SAPO-34-S10 (Si 8-12 mol%): balanced ethylene/propylene
- SAPO-34-S15 (Si 12-15 mol%): higher acidity, propylene shift
- Spray-dried microspheres (60-100 μm) for fluidized bed MTO
- Powder form for fixed-bed screening and catalyst formulation
Certificate of Analysis
Every shipment includes a batch-specific COA with: chemical composition (Si, Al, P by XRF), BET surface area, particle size distribution, LOI, and XRD crystallinity. Additional parameters on request: SEM imaging, NH₃-TPD acidity, thermal analysis (TGA/DSC).
To request a sample with COA, specify your target Si content, reactor type (fluidized bed or fixed bed), and desired particle form.
