Molecular Sieve 3A Beads
Product Description
3A Molecular sieve
Usually molecular sieves are composed of aluminosilicate minerals, but there are also synthetic mixtures or compounds. These compounds have an open structure that allows small molecules to diffuse, such as: clay, porous glass, microporous charcoal, activated carbon, etc.
Molecular sieves are often used in the petroleum industry, especially for gas purification. For example, silica gel can be used to absorb mercury in natural gas to corrode aluminum pipelines and other liquefaction equipment.

Regeneration:
3Å molecular sieves do not adsorb molecules whose diameters are larger than 3 Å. The characteristics of these molecular sieves include fast adsorption speed, frequent regeneration ability, good crushing resistance and pollution resistance. These features can improve both the efficiency and lifetime of the sieve. 3Å molecular sieves are the necessary desiccant in petroleum and chemical industries for refining oil, polymerization, and chemical gas-liquid depth drying.
3Å molecular sieves are used to dry a range of materials, such as ethanol, air, refrigerants, natural gas and unsaturated hydrocarbons. The latter include cracking gas, acetylene, ethylene, propylene and butadiene.
Package & store:
Indoors with room temperature and relative humidity not greater than 90%: avoid water, acid, alkali, and isolate the air, and store in airtight.
Packing 25KG/piece. Specific can be based on customer requirements.
Shelf life: minimum 2 years.
Note: Avoid direct exposure of molecular sieve to air.
