Activated alumina

Activated alumina

Description:Activated Alumina has the advantages of large surface area, high strength, thermal stability, many micro-pores, well disperser, so it has a high affinity for water/impurity and active catalyst. According to the applications of balls, there are 6 types of Activated Alumina Sorbent, Activated Alumina Desiccant and Activated Alumina Catalyst carrier,Activated Alumina Defluoridizer, Activated Alumina Antichlor, Activated Alumina Absorbent In Air Separation, Activated Alumina Absorbent For H22. Meantime interior composition of the crystal phase was divided into mode Y and X-P.The activated alumina are widely utilized in the drying agent of multiform gas and liquid, also function is used as a sorbent, desiccant, catalyst carrier in reactors for petrochemical industry, chemical industry, fertilizer industry and so on.Technical Property of Activated Alumina
