Understanding Molecular Sieve 4A
Molecular Sieve 4A, also known as Molekularsieb 4A, is a type of molecular sieve that is widely used in various applications. It is a functional term for natural and synthetic zeolites or other substances that have a high adsorption capacity for gases, vapors, and dissolved substances of certain molecular sizes.Get more news about Molekularsieb 4a,you can vist our website!

The 4A in its name refers to its effective pore opening of approximately 4 Angstroms. This means it can adsorb molecules with an effective diameter of less than 4 Angstroms. Examples of such molecules include H2O, CO2, SO2, H2S, C2H4, C2H6, and C3H. However, it excludes molecules like C3H8 and higher hydrocarbons.

One of the key features of Molecular Sieve 4A is its high water adsorption capacity at low partial pressures and at temperatures up to 100 °C. This makes it particularly useful in applications that require the drying of gases and solvents.

In addition to its high adsorption capacity, Molecular Sieve 4A also exhibits a large internal surface area and uniform pore diameters, which are in the order of the diameters of molecules1. This allows for the separation of molecules of different sizes, making Molecular Sieve 4A a valuable tool in various industrial applications.

In conclusion, Molecular Sieve 4A is a versatile adsorbent that plays a crucial role in many different applications. Its unique properties, such as its high adsorption capacity and ability to separate molecules of different sizes, make it an invaluable tool in various industries.
