Activated alumina desiccant is spherical activated alumina made by special process. Its properties are non-toxic, odorless, non-pulverizing, insoluble in water, white spherical in appearance, and strong in absorbing water.
Under certain operating conditions and regeneration conditions, its drying depth is as high as the dew point temperature below -70°C, and it is a highly efficient desiccant for deep drying of trace water. Activated alumina desiccant is mainly used for drying liquid and gas. Although all molecules are absorbed to some extent, molecules with strong polarity are preferentially absorbed. The pressure, concentration, molecular weight, temperature and active sites of the gas will all affect the adsorption effect. The common sizes of activated alumina desiccants are spherical 1/16", 1/8", 3/16", 1/4". It is widely used in gas and liquid phase drying of petrochemical industry, drying of textile industry, oxygen production industry and automatic instrument air, pressure swing adsorption in air separation industry, etc. Due to the high net heat of the monomolecular adsorption layer, it is very suitable for a heatless regeneration device.
Activated alumina has the characteristics of large adsorption capacity, large specific surface area, high strength, and good thermal stability. The following introduces the structure of activated alumina: activated alumina has spherical particles with many capillary channels, which are highly polar to water and other molecules. substance. It has a strong affinity and is a non-toxic, non-corrosive and effective desiccant with high static capacity. It is used as adsorbent, desiccant, catalyst and its carrier in many reaction processes such as petroleum, chemical fertilizer and chemical industry.
Activated alumina is one of the inorganic chemical products widely used in the world. The following introduces the performance of activated alumina: activated alumina has good stability and is suitable for desiccant, catalyst carrier, fluoride removal agent, pressure swing adsorbent, hydrogen peroxide special regeneration agent, etc. Activated alumina is widely used as catalyst and catalyst carrier.
