Molecular sieve 13X

Molecular sieve 13X

Chemical Formula:

Na86[(AlO2)86(SiO2)106]·XH2O

Introduction:

X-type crystal sodium, a kind of aluminosilicate of alkali metal. Molecular sieve 13X can adsorb molecules whose critical diameter is not more than10

Uses:

used to dry gas, purify the raw material of air separation equipment (get rid of H2O and CO2 at the same time) and desulfurate from liquid hydrocarbon and natural gas (get rid of H2S and thio -alcohol).
Molecules which can be adsorbed by molecular sieve 3A, 4A and 5A can be adsorbed by 13X. Besides, 13X can adsorb molecule whose diameter is a little less than critical diameter, such as some aromatic hydrocarbon and branched-chain hydrocarbon.

Regeneration:

it can be regenerated through the course of ventilating or exhausting while improving the temperature. Regeneration temperature is 180-350°C , and regeneration time is 3-6 hours.

Packing:

sealed iron drum 25kg, 50kg, 136kg.

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 use after regenerated if absorbing moisture for being kept for a long time. The maximum regeneration temperature is 600°C
