Product Description

4A Molecular Sieve is somewhat similar to 3A Molecular Sieve, but there are also some differences. The following are the main characteristics of 4A Molecular Sieve:

Pore size: The pore size of 4A molecular sieve is about 4 angstroms (1 angstrom = 10^-10 meters), which is slightly larger than 3A molecular sieve, but is still suitable for adsorbing smaller molecules, such as water and some small molecule gases.
Calcium ions: The structure of 4A molecular sieve contains calcium ions. These ions help maintain the structural stability of the molecular sieve and affect its adsorption and separation performance.
Adsorption capacity: 4A molecular sieve has strong adsorption capacity, especially for small molecular gases such as water molecules, methane, ethane, ethanol, etc. It has high selective adsorption capacity.
Separation efficiency: Due to its moderate pore size, 4A molecular sieve shows good separation efficiency when separating water molecules, ammonia molecules and some small molecule gases in mixed gases.
Thermal stability: 4A molecular sieve has good thermal stability within a certain temperature range and can work stably at relatively high temperatures.
Chemical stability: 4A molecular sieve has good chemical stability in general chemical environments and can resist a certain degree of acid and alkali erosion and the effects of other chemical substances.
Regeneration performance: When the adsorption of 4A molecular sieve is saturated or fails, its adsorption performance can be restored and its service life extended through appropriate regeneration methods (such as heating, etc.).

Scope of application: 4A molecular sieve is commonly used in natural gas dehydration, air separation, gas drying, lubricating oil dehydration and other fields, and has extensive applications in chemical, petroleum, pharmaceutical and other industries.
