4A molecular sieve Product introduction and application

4A molecular sieve Product introduction and application


4A molecular sieve is a kind of silicate crystal with unique adsorption property, and its chemical formula is Na2Al2Si12O24-12H2O. it is a synthetic substance with good thermal stability and acid resistance, which is widely used in the fields of catalysts, desiccants, adsorbents and so on.


The crystal structure of 4A molecular sieve consists of silicate ions and hydroxide ions, showing a three-dimensional pore structure. These pores can effectively adsorb gas and liquid molecules with high specific surface area and pore volume. Due to its unique pore size and adsorption properties, 4A molecular sieve has a wide range of applications in many fields.

1. In the field of catalyst, 4A molecular sieve can be used as catalyst carrier, loaded with metal or metal oxide catalysts for catalytic reaction process in petrochemical, environmental protection and other fields. Its excellent adsorption properties and structural stability make it an efficient catalyst carrier.

2. In the field of desiccant, 4A molecular sieve has high water-absorption capacity and excellent moisture resistance, which is widely used in various occasions requiring drying, such as drying of industrial gases, drying of medicines and so on. With its strong water-absorbing capacity and good drying effect, it can effectively remove water from gases and liquids.

3.In the field of adsorbent, 4A molecular sieve has a large specific surface area and pore capacity, which can effectively adsorb harmful substances and impurities in gases and liquids. It is widely used in air purification, water treatment and other fields.
