What is Molecular Sieve?

A molecular sieve is a synthetic molecular sieve material with pores of precise and uniform structure and size. This enables them to preferentially adsorb gases and liquids based on molecular size and polarity. Zeolite molecular sieves are naturally occurring highly porous crystalline solids that belong to a class of chemicals known as aluminosilicates.

The usefulness of molecular sieve

Molecular sieves are used to dry gases and liquids and to separate molecules according to their size and shape. When two molecules are equally small and can enter the pores, the separation is based on the polarity of the molecules (charge separation), with the more polar molecule being preferentially adsorbed.

What are the types of molecular sieves?

There are four main types of sieves: molecular sieve 3A, molecular sieve 4A, molecular sieve 5A and molecular sieve 13X. The type of molecular sieve depends on the chemical formula of the molecule, which determines the size of the pores.

Molecular sieves work by adsorbing gas or liquid molecules whose effective diameter is larger than the pores, except for gas or liquid molecules with larger openings. The molecular sieve related to this field is type 3A, and the molecular sieve used for insulating glass is called 3A.

3A molecular sieve has fast adsorption speed and high recovery frequency, which explains the oil well damage and pollution. 3A molecular sieve is used in the drying of gasoline, polymerization, chemical gas-liquid dry refining and the petrochemical industry.

How to use a molecular sieve?

Molecular sieves are used for dehydration and solvent dehydration is used in the final stage of embedding. Molecular sieves are typical zeolite compounds that strongly adsorb water and have carefully controlled pore sizes.

How does a molecular sieve remove water?

Molecular sieves are crystalline metal aluminosilicates with a three-dimensional interconnected network of silicon-aluminium tetrahedra. The natural water of hydration is removed from this network by heating, creating uniform cavities that selectively adsorb molecules of specific sizes.
