Product Description

3a Molecular Sieve Desiccant For  LNG Purification 2-3mm, 3-5mm, 4-6mm
Molecular sieve (as known as synthetic zeolite) is a micro-porous aluminosilicate crystals. It is made of the silicon-oxy tetrahedron, alumina tetrahedron to form a basic skeleton structure, in which exist metal cations (e.g. Na+, K+, Ca2+, etc.) to balance the excess negative charge in the crystal. According to the type of crystal structure, zeolite consists of: A-type (LTA), X-type (FAU), Y-type and so on.

The adsorption capacity of molecular sieve comes from the physical adsorption (van der Waals force). The crystal has a strong polarity and Coulomb field, which show a strong adsorption capacity for polar molecules (water) and unsaturated molecules.
The pore size of molecular sieve distribution is very consistent. Only when the molecular diameter is less than the pore size of molecular sieve, the molecule is possible adsorbed into the crystal cave.
Distinguishing molecules of different substances by the priority of adsorption and the sizes, it is vividly called "molecular sieve".

To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
