Activated Alumina desiccan absorbent 3A/4A/5A-Aluminium products-China Aluminium Network

Detail Information

The use of alumina in the catalyst is commonly referred to as "activated alumina", which is a porous, highly dispersible solid material with a large surface area and a microporous surface with the properties required for catalysis, such as It is widely used as a catalyst for chemical reactions and a catalyst carrier because of its adsorption properties, surface activity, excellent thermal stability and the like. The spherical activated alumina pressure swing oil adsorbent is white spherical porous particles, the activated alumina has uniform particle size, smooth surface, high mechanical strength, strong hygroscopicity, no swelling and no cracking after being absorbed, and is non-toxic, odorless and insoluble. Water, ethanol.
