Activated alumina desiccant is a spherical activated alumina made by a special process. Its inherent properties are non-toxic, odorless, non powdering, insoluble in water, with a white spherical appearance and strong ability to adsorb water.

1.brief introduction

Under certain operating and regeneration conditions, its drying depth can reach below the dew point temperature of -70 ℃, making it an efficient desiccant for deep drying of trace amounts of water. Activated alumina desiccant is mainly for drying liquids and gases. Although it can absorb all molecules to a certain extent, it will preferentially absorb molecules with strong polarity. The pressure, concentration, molecular weight, temperature, and active sites of the gas can all affect the adsorption effect. The common sizes of activated alumina desiccants are spherical 1/16 “, 1/8”, 3/16 “, and 1/4”. Widely for gas and liquid phase drying in the petrochemical industry, drying in the textile industry, oxygen production industry, and automation instrument air, as well as pressure swing adsorption in the air separation industry. Due to the high net heat of the single-molecule adsorption layer, it is very suitable for non thermal regeneration devices.

2.The structural properties of activated alumina:

Activated alumina has the characteristics of large adsorption capacity, large specific surface area, high strength, and good thermal stability. Below is an introduction to the structure of activated alumina: Activated alumina has spherical particles with many capillary channels and strong polarity towards molecules such as water. It has strong affinity and is a non-toxic, non corrosive desiccant with high static capacity. It is as an adsorbent, desiccant, catalyst, and carrier in many reaction processes such as petroleum, fertilizer, and chemical engineering.

Activated alumina is one of the widely use inorganic chemical products in the world today. Here is an introduction to the properties of activated alumina: Activated alumina has good stability and is suitable for use as a desiccant, catalyst carrier, defluoriner, pressure swing adsorbent, hydrogen peroxide specific regenerant, etc. Activated alumina is widely use as a catalyst and catalyst carrier.
