X-type crystal sodium, a type of aluminosilicate of alkali metal. Molecular sieve 13X adsorbs molecules whose critical diameter is not more than 10A.
Used to dry gas, purify raw material in air separation equipment (removal of H2O and CO2 at the same time) and removes sulfur compounds from liquid hydrocarbons and natural gas (removal of H2S and thio-alcohol).
Molecules which can be adsorbed by molecular sieve 3A, 4A and 5A can also be adsorbed by 13X. 13X can also adsorb molecules whose diameter is a little less than critical diameter, such as some aromatic hydrocarbon and branched-chain hydrocarbon.
By increasing the temperature, it is capable of regeneration through the course of ventilation or exhaust.
Na86[(AlO2)86(SiO2)106]. XH2O
CAS No: 63231-69-6
Can be packed in form of globular or sticklike into sealed 40 kg iron drum; to be stored in a dry environment.
