3A,4A,5A zeolite molecular sieve, 13X what's the difference, you know?

3A zeolite molecular sieve mainly adsorbs water
4 a zeolite molecular sieve is mainly used in the air, gas and other chemical gas and liquid, frozen agent, medicine, electronic materials, and the depth of the volatile matter is dry, argon gas purification, separation of methane, ethane, and propane.
The choice of water is higher than that of any other molecule.
5 a zeolite molecular sieve type calcium it besides 3 a, 4 a molecular sieve has the effect of outside, still can adsorption C3, C4, the corresponding normal alkanes was ethyl chloride, bromine ethane, butyl alcohol, etc., can be applied to are heterogeneous hydrocarbon separation, pressure swing adsorption separation and total absorption of water and carbon dioxide.
13 x zeolite molecular sieve silica alumina ratio: SiO2 / AL2O3 material is 2.6 to 3.0 in order to meet the special requirements of air separation industry, further improve the ability of zeolite molecular sieve adsorption of carbon dioxide and water, avoid frozen tower phenomenon appeared in the process of air separation and production of special molecular sieve, also can be applied to oxygen enrichment.
Application: 1. Purification of the gas in the air separation unit (simultaneously removing the removal of water and carbon dioxide).
2. Natural gas, liquefied petroleum gas desulfurization (removing hydrogen sulfide and mercaptan)
3. Deep drying and purification of industrial gases can also be used as carriers.
The type 13X can be adsorbed by all technical indexes that can be adsorbed on triple-a, 4A and 5A molecular sieve.
