Application of different types of molecular sieves

Molecular sieve according to SiO2 and Al2O3 molecular ratio is different, get different pore size of the product, so that it has a variety of models, 3A, 4A, 5A, etc., because they will have some differences in performance and other aspects, so their application scope is also different.

3A molecular sieve is mainly used in: chemical industry, petroleum, medicine, insulating glass and other industrial dry agent, used for unsaturated hydrocarbon materials, such as cracking gas, butadiene, propylene, acetylene and other industrial dehydration, can also be used for gas, polar liquid and natural gas dry. Because the pore size of 3A molecular sieve is small, it can effectively control the co-adsorption of other molecules in the adsorption process.

4A molecular sieve is mainly used in: closed gas or liquid system to stop static dehydration. Used as static drying agent in household refrigeration systems, pharmaceutical packaging, automotive air conditioning, electronic components, degenerating chemicals or as dehydrating agent in coating and plastic systems. In industry, it can also be used for boring saturated hydrocarbon materials.

And can absorb methanol, ethanol, hydrogen sulfide, carbon dioxide and so on. Can be used in R-12 and R-22 systems. It can also be used for separation and purification of gas and liquid components, such as argon purification and preparation of anhydrous ethanol. 3A molecular sieve can adsorb molecular 4A molecular sieve can be adsorbed.

5A molecular sieve is mainly used in: the separation of isomerized alkanes, oxygen and nitrogen separation, chemical industry, petroleum gas, ammonia synthesis gas and other industrial gases and liquid dry and refined.

No matter which type of molecular sieve, they have different characteristics and advantages, play an important role in different industries, so the correct choice of the right model is very necessary.
