Zeolite molecular sieves have the structure and characteristics of crystals, the surface is a solid skeleton, and the internal holes have the function of adsorbing molecules. There are pores connected to each other, and molecules pass through the pores channels. Due to the crystalline nature of the pores, the pore size distribution of molecular sieves is very uniform. Molecular sieves selectively adsorb molecules according to the size of the holes in their crystal, that is, they adsorb molecules of a certain size and repel molecules of larger substances, so they are figuratively called "molecular sieves."
5A molecular sieves are usually formed by the exchange of calcium ions to 4A molecular sieves instead of sodium ions. Divalent calcium ions make it an excellent choice for removing carbon dioxide, CO, hydrogen sulfide, and other weakly polar molecules.
5A molecular sieves can be widely used in the separation of n-isomer hydrocarbons, pressure swing adsorption separation, and co-adsorption of water and carbon dioxide.

Storage
Prevent the molecular sieves from exposing directly to the damping environment and any absorption of water or organic substance before it's used, otherwise it must be regenerated. All Chemequip molecular sieves can be regenerated by temperature or pressure swing.
Delivery
For small quantity order < 100kg, 10 days after purchased contract is efficient.
For big quantity order > 500kg, 15 days after purchased contract is efficient.
