Can 4A molecular sieves adsorbent be reuse?

4a molecular sieve is a powdery crystal with metallic luster, hardness of 3-5, relative density of 2-2.8.

Natural zeolite has color, while synthetic zeolite is white and insoluble in water.

Moreover, its thermal stability and acid resistance increase with the increase of SiO2/Al2O3 composition ratio.

Molecular sieves have a large specific surface area of 300-1000m2/g, with highly polarized inner crystal surfaces.

They are a highly efficient adsorbent and a solid acid with high acid concentration and strength on the surface, which can cause catalytic reactions of carbocation type.

When the metal ions in the composition exchange with other ions in the solution, the pore size can adjust to change their adsorption and catalytic properties, thereby producing molecular sieve catalysts with different properties.

4A molecular sieves use in air seperation equipment

Molecular sieve adsorbents mainly use in air separation equipment, natural gas dehydration, alkane circulation purification, refrigerant and drying of various electronic components.

It has strong adsorption capacity, high water absorption and selective water absorption, surpassing any other molecule.

In addition, 4A molecular sieve can also adsorb methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, etc.

After adsorption saturation, regeneration treatment can be carried out to eliminate molecules adsorbed on 4A molecular sieve spheres, and adsorption can be carried out again.

The main method of regeneration treatment is to increase the regeneration temperature, usually by raising the temperature of the high-temperature gas to 200 degrees and removing the moisture and other molecular sieves inside the sphere.

After high-temperature regeneration, 4A molecular sieve regain their activity and undergo adsorption work.

In this way, adsorption and regeneration alternate operation.

The service life of a typical 4A molecular sieves adsorbent is 3-5 years.

After prolonged use, vitality will gradually decrease.
