Product introduction
Molecular Sieve 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). RP type 4A molecular sieve will adsorb most molecules with a kinetic diameter of fewer than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.

Scope of application
a) Drying and removing of CO2 from natural gas, LPG, air, inert and atmospheric gases, etc.
b) Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)
c) Special types are used in the air break units of buses, trucks and locomotives.
d) Packed in small bags, it may be used simply as a packaging desiccant
Product Pictures
Product Features
1. Adsorption is selective.
⑴ Choose the adsorption according to the different molecular diameter.
⑵ Select the adsorption according to the polarity of the molecule.
⑶ Selective adsorption according to the degree of molecular unsaturation.
⑷ Select adsorption according to different boiling points.
2. It has low concentration and high adsorption characteristics at higher temperature.
3. Cation exchange characteristics.
4. Catalytic properties.
⑴ The heterogeneous catalytic reaction is carried out on the surface of the catalyst. When the molecular sieve is used as a catalyst or carrier, the catalytic reaction is to catalyze the substances entering the micropores of the molecular sieve.
⑵ Only produce products whose molecules are smaller than the pores of the molecular sieve.
⑶ Because of the large surface area, it has high activity.
⑷ Strong resistance to poisoning and high thermal stability.
⑸ When used as a carrier, the metal catalyst can be evenly distributed on the inner surface of the molecular sieve, so it is easy to prepare a catalyst with good repeatability.
