Activated alumina
Activated alumina is widely applied in chemical, petrochemical, fertilizer industries.
Product name: Activated alumina
Merits: big adsorption capacity, big surface area, high intensity, good thermal stability and so on. It is often used as support for adsorbent, desiccant and catalyst in chemical, fertilizer petrochemical industries.
