Activated Alumina Desiccant

Activated alumina desiccant is a spherical activated alumina made by special process. Its own properties are non-toxic, odorless, non-powdered, insoluble in water, white ball appearance, strong ability to absorb water.

Under certain operating conditions and regeneration conditions, its drying depth is as high as the dew point temperature below -70℃, and it is a highly efficient desiccant for the depth drying of trace water. Activated alumina desiccant is mainly used to dry liquids and gases. Although it can absorb all molecules to a certain extent, it preferentially absorbs molecules with strong polarity. The pressure, concentration, molecular weight, temperature of the gas and the active site of the molecule all affect the adsorption effect. The common size of activated alumina desiccant is ball shape 1/16 ", 1/8 ", 3/16 ", 1/4 ". It is widely used in gas and liquid phase drying of petrochemical industry, textile industry, oxygen industry and automatic instrument wind drying, air separation industry pressure swing adsorption, etc. Due to the high net heat of the single molecular adsorbent layer, it is very suitable for non-heat regeneration devices.

Structural properties of activated alumina:

Activated alumina has the characteristics of large adsorption capacity, large specific surface area, high strength, good thermal stability, etc. The following describes the structure of activated alumina: Activated alumina has many spherical particles with capillary channels, substances with strong molecular polarity such as water. It has a strong affinity, is a non-toxic, non-corrosive effect desiccant, its static capacity is high. It is used as adsorbent, desiccant, catalyst and carrier in many reaction processes such as petroleum, fertilizer and chemical industry.

Activated alumina is one of the most widely used inorganic chemical products in the world. The following describes the performance of activated alumina: activated alumina has good stability, suitable for desiccant, catalyst carrier, defluorination agent, pressure change adsorbent, hydrogen peroxide special regenerant and so on. Activated alumina is widely used as catalyst and catalyst carrier.
