5A molecular sieve can adsorb any molecule smaller than this pore size, and is generally called calcium molecular sieve. In addition to the effects of 3A and 4A molecular sieves, it can also adsorb C3-C4 n-alkanes, chloroethane, bromoethane, butanol, etc. It can be used in the separation of normal isomers, pressure swing adsorption separation and water Co-adsorption with carbon dioxide. Based on the industrial application characteristics of 5A molecular sieves, the 5A molecular sieves we produce have high adsorption selectivity, fast adsorption speed, and are especially suitable for pressure swing adsorption. It is an excellent product in the pressure swing adsorption industry.
Molecular formula: 3 / 4CaO · 1 / 4Na2O · AI2O3 · 2SiO2 · .9 / 2H2O
Silicon to aluminum ratio: SiO2 / AI2O3 ≈ 2
Effective aperture: about 5A
Application: It is mainly used for the separation of normal isomers, oxygen and nitrogen, chemical industry, petroleum and natural gas, ammonia decomposition gas and other industrial gases and liquids.
1. Removal of water: It depends on the pressure, temperature and water content of the regeneration gas. Generally, the dry gas at 200 ～ 350 ℃ is 0.3 ～ 0.5kg / cm2.
Under pressure, pass through the bed of molecular sieve for 3 to 4 hours to cool the outlet temperature to 110-180 ° C.
2. Removal of organic matter: use steam to replace organic matter, and then remove water.
Storage: room temperature, relative humidity is not more than 90%; it should not be directly exposed to the air; avoid water, acid and alkali.
Packaging: 25KG cardboard drum or bag. According to customer requirements.
Note: Avoid direct exposure of molecular sieves to the air, which will affect the adsorption effect.
