Production of activated alumina

氧化铝.jpg

There are two raw materials for the production of activated alumina. One is "quick-release powder" produced by gibbsite or Bayer stone, and the other is pseudo-boehmite produced by aluminate or aluminum salt or both.


Production of x-ρ alumina


x-ρ alumina is the main raw material for the production of activated alumina balls. It is abbreviated as FCA abroad. In China, it is called "quick dehydration powder" because it is an alumina powder produced by a rapid dehydration method. "Quick release powder" is a mixture of x-alumina and ρ-alumina. Due to differences in production conditions, the content varies.


Production method of pseudo-boehmite


Natural or artificially produced alumina monohydrate and alumina trihydrate cannot be used as desiccants, adsorbents, catalysts and catalyst carriers due to their low specific surface area, small pore volume and low activity. Alumina monohydrate or alumina trihydrate must be processed into pseudo-boehmite. Pseudo-boehmite has high specific surface area, large pore volume, large pore diameter, and high activity. It is suitable for use as desiccant, adsorbent, catalyst and catalyst carrier in the fields of petrochemical industry, fertilizer and exhaust gas.
