Chemical Formula: |
Na56[(AlO2)56(SiO2)136]·XH2O |
Introduction: |
NaY molecular sieve is a kind of alkaline metal aluminosilicate salts with Y-type crystalline structure of sodium salt. It can absorb molecules with critical diameter not more than 10  . |
Uses: |
Catalyst or catalyst carrier. Suitable for molecules that can be absorbed by 3A, 4A, 5A type molecular sieve and some molecules with small critical diameter, like aromatic hydrocarbon or branched hydrocarbon. |
Regeneration: |
Placed in vacuum or dry air flow under elevated temperature(180-350℃) for 3-6 hours. |
Packing: |
sealed iron drum 25kg, 50kg, 136kg. Powder or sphere. |
