Structure of activated alumina:
Active alumina has the advantages of large adsorption capacity, large specific surface area, high strength and good thermal stability. The following describes the structure of activated alumina: Activated alumina has many spherical particles with capillary channels and is highly polar to molecules such as water substance. It has a strong affinity, is a non-toxic, non-corrosive desiccant, its high static capacity. It is used as adsorbent, desiccant, catalyst and carrier for many reactions in petroleum, chemical fertilizer and chemical industry.
