Chemical Formula: |
Ca4.5Na3[(AlO2)12(SiO2)12]·XH2O |
Introduction: |
5A type crstyal structure calcium. It is a kind of aluminosilicate of alkali metal. It can adsorb molecules whose critical diameter is not more than 5 . |
Uses: |
it can used to separate normal paraffin from branched hydrocarbon and cricoid hydrocarbons through selective adsorption. Now, it is largely used in the separation of normal paraffin and isoparaffin. Molecules which can be adsorbed by molecular sieve 3A and 4A could be adsorbed by the molecular sieve 5A. |
Regeneration: |
it can be regenerated through the course of ventilating or exhausting while improving the temperature. Regeneration temperature is 180-350°C, and regeration time is 3-6 hours. |
Packing: |

Amount of H2O adsorbed by every 100g of activated molecular sieve under the normal pressure and at 35°C. |
Points of Attention: |
Packed in sealed iron drum and put in dry place;
PH value for application is 5-11;
It can be used after regenerated if absorbing moisture for being kept for a long time. The maximum regeneration temperature is 600°C. |
