作者 浏览 发布时间 2019/3/21 21:05:17

  

Product Characteristics and Application Scope

4A zeolite is a kind of alkali metal aluminosilicate, which can adsorb hydrogen peroxide, NH3, H2S, SO2, C02, C2H5OH, C2H6, C2H4 molecules with critical diameter less than 4A. It is widely used in the drying of gases and liquids. It can also be used in the refining and purification of some gases or liquids, such as the preparation of argon.

4A molecular sieves are used as re-cattle (, under the purge of Ran gas, the adsorbed water is removed from the zeolite and reused for regeneration). The degree of regeneration depends on the time of regeneration and the temperature and humidity of regenerated gas.
