Y Zeolite TDS
This technical data sheet covers standard specification ranges for Y zeolite catalyst in Na-Y, NH₄-Y, and derived HY/USY forms. Na-Y is the precursor for FCC and hydrocracking catalyst manufacturing. Custom SAR, sodium level, and crystallinity available on request.
Typical Specifications
| Parameter | Na-Y | HY / USY | Test Method |
|---|---|---|---|
| SiO₂/Al₂O₃ (molar) | 2.5-6 | 3.5-80+ | XRF |
| BET surface area | 600-800 m²/g | 600-800 m²/g | N₂ adsorption |
| Pore size | ~7.4 Å | ~7.4 Å | 12-MR FAU |
| Supercage diameter | ~12 Å | ~12 Å | Structural |
| Unit cell size | 24.50-24.70 Å | 24.24-24.70 Å | XRD |
| Na₂O content | 2-13 wt% | ≤0.10 wt% | XRF or AAS |
| Particle size (D50) | 0.5-5 μm | 0.5-5 μm | Laser diffraction |
| XRD crystallinity | ≥90% | ≥85-90% | vs FAU reference |
| Framework | FAU | FAU | XRD confirmation |
Available Forms
- Na-Y powder (ion-exchange precursor, adsorption grade)
- NH₄-Y powder (direct conversion to HY)
- HY powder (proton-exchanged, acidic)
- USY powder or microspheres (dealuminated, hydrothermally stable)
Certificate of Analysis
Every shipment includes a batch-specific COA. For Na-Y: SiO₂/Al₂O₃, Na₂O, BET, unit cell size, particle size, LOI, and XRD. For HY/USY: all above plus confirmation of Na₂O ≤0.1 wt%. Additional parameters on request: SEM, ion-exchange capacity, MAS NMR.
To request a sample with COA, specify whether you need Na-Y precursor, NH₄-Y intermediate, or finished HY/USY.
