High specific surface area of molecular sieve

Molecular sieve has a large specific surface area (usually up to 300-1000m²/g), providing a rich adsorption site and significantly improving adsorption efficiency.

2. The molecular sieve pore structure is uniform

Its pore size is uniform and distributed in an orderly manner, and the pore size range is usually between 0.3-2 nanometers. It can accurately screen according to the size of the molecule and effectively separate different molecules.

3. Strong adsorption selectivity of molecular sieve

It has preferential adsorption capacity for polar molecules, unsaturated molecules and small molecules. The adsorption strength is: water > ammonia > hydrogen sulfide > sulfur dioxide > carbon dioxide, which is suitable for the separation and purification of complex components.

4. High efficiency of molecular sieve water absorption

Maintaining high water absorption capacity under high temperature, high flow rate or low moisture content conditions is an ideal material for gas drying and liquid dehydration.

5. Thermal stability and acid resistance of molecular sieve

Thermal stability increases with the increase of SiO₂/Al₂O₃ ratio. Some molecular sieves can withstand high temperatures of 1100℃; they have good acid resistance, but are soluble in strong acids.

6. Adsorption and catalytic properties of molecular sieve adjustable

The pore size and surface electric field distribution can be changed through ion exchange, thereby adjusting adsorption selectivity; at the same time, when used as a catalyst support, catalytic activity and stability can be improved.

7. Molecular sieve regeneration ability

After adsorption is saturated, desorption and regeneration can be achieved through heating or decompression, and the adsorption capacity can be restored, and the recycling cost is low.

 

In addition to adsorption and catalysis, molecular sieves also have ion exchange, shape selection catalysis and other characteristics, and can be used in gas separation, liquid dehydration, waste gas treatment, water treatment, and medicine, food, agriculture and other fields.
