The difference between zeolite and activated alumina

1. Molecular sieves and activated alumina balls can be used as desiccants.

Second, the difference between molecular sieve and activated alumina sphere is different in application:
1. Molecular sieves have strong moisture absorption capacity and are used for purification of gases. Avoid direct exposure to air during storage. Molecular sieves that have been stored for a long period of time and have been hygroscopic should be regenerated before use. Molecular sieves avoid oil and liquid water. Avoid contact with oil and liquid water when using.
2. Activated alumina balls are mainly used for dehydration and drying of industrial gases such as chemical, metallurgy, electronics and petroleum, such as permanent gases such as air, oxygen and nitrogen, smelting gas and petroleum cracking gas.

3. The difference between molecular sieve and activated alumina sphere is different in technical indicators.

 
4. The difference between molecular sieve and activated alumina sphere is characterized by different characteristics:
    Activated Alumina: Activated alumina is a white globular substance. It is made by a special process. Because of its unique skeleton structure, it has strong affinity with active components. The product has uniform pore distribution, suitable pore size, and high water absorption capacity. It has small bulk density, good mechanical properties and good stability. It is suitable for desiccant, catalyst carrier, defluorination agent, pressure swing adsorbent and special regenerating agent for hydrogen peroxide.
    Molecular sieves have a large specific surface area of 300-1000 m2/g, and the inner crystal surface is highly polarized. It is a kind of high-efficiency adsorbent and a kind of solid acid. The surface has high acid concentration and acid strength, which can cause positive carbon ions. Catalytic reaction. When the metal ions in the composition exchange with other ions in the solution, the pore size can be adjusted, and the adsorption and catalytic properties can be changed to obtain molecular sieve catalysts with different properties.
    In fact, the simplest difference between molecular sieves and activated alumina spheres is that zeolites are mainly composed of three kinds of aluminum silicates, and molecular sieves with different pore sizes are formed according to different guiding agents, and their catalytic properties depend on the distribution of acid centers. Adsorption properties depend on physical factors such as pore size and specific surface area.
