Alumina used in catalysts is usually specially called "activated alumina". It is a porous and highly dispersed solid material with large surface area. Its microporous surface has the characteristics required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc. Therefore, it is widely used as catalyst and catalyst carrier for chemical reaction. Spherical activated alumina pressure swing oil adsorbent is white spherical porous particles. Activated alumina has uniform particle size, smooth surface, high mechanical strength and strong moisture absorption. It does not swell or crack after water absorption, and remains unchanged. It is non-toxic, odorless and insoluble in water and ethanol. Activated alumina is an efficient desiccant for deep drying of trace water, which is suitable for heatless regeneration device.

Our company 4N and 5N high purity activated alumina is a kind of white powder, large specific surface area, easy to disperse, soluble in strong acid and alkali solutions, and has strong hygroscopicity in air

4N and 5N high purity activated alumina was widely used in Catalyst, catalyst support,chromatography agent,adsorbent,desiccant and so on

We also have other type 4N and 5N high purity activated alumina , contact with us for OEM
