3.5mm 4A DG1/8" Molecular Sieve Dryer

3.5mm 4A DG1/8" Molecular Sieve Dryer

Product introduction

The 4A molecular sieve adsorbent has a 4 angstrom (4A) pore size; this means that any molecule that is larger than the 4 angstrom pores will not be adsorbed. The 4A molecular sieve is composed of the sodium type of A crystalline structure. For a 4A molecular sieve, the sequence rate that adsorption occurs is Ar, Kr, Xe, NH3, CO, CO2, C2H2, CH3Br, C2H4, CH3OH, CH3CN2, CS2, and CH3CL.

Due to the crystalline structure, molecular sieves that have a 4 angstrom pore size have a very high rate of adsorption and properties—including an increased resistance to outside contamination and crushing strength stronger than other desiccants—that promote a longer life for products treated by the sieve. The most common use for the 4A molecular sieve is to remove water and moisture from materials that are in gas and liquid form.

4A molecular sieve technical Index:

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 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.
