What is the difference between zeolite and activated alumina?

Zeolite molecular sieves and activated alumina are industrial adsorbents, and the adsorption mechanism is the same. Generally, in the case of gas-liquid adsorption, zeolite molecular sieves and activated alumina are generally used together, and activated alumina is generally used in the lower part of the purifier for pretreatment. Zeolite molecular sieves are used for the later finer purification adsorption.

    Zeolite molecular sieves have a very good ability to absorb moisture and are used for the purification of gases. Avoid direct exposure to air during storage. Molecular sieves that have been stored for a long time and that are already hygroscopic should be regenerated before use. Zeolite molecular sieve avoid oil and liquid water. When using, avoid contact with oil and liquid water. Activated alumina balls are mainly used for the dehydration of industrial gases such as chemicals, metallurgy, electronics, and petroleum, such as permanent gas smelting gases such as air, oxygen, and nitrogen, and petroleum pyrolysis gas. The activated alumina produced by our company is a high-strength x-ρ alumina product with many pores. The strong affinity for water is a kind of desiccant for deep drying of trace amounts of water. It has the characteristics of liquid softening, non-swelling and non-powdering when soaked with water in the use of liquids. Drying in the liquid phase, the textile industry, the oxygen industry, and automated instrumentation. The static water equilibrium adsorption of 13X zeolite molecular sieve can reach about 23%. Activated alumina looks like 17%.
