Activated alumina has various good characteristics. So it also uses by more and more industries. Below, we will introduce the characteristics and applications of activated alumina carriers.
The use of alumina in catalysts is commonly as “activated alumina”. It is a porous, highly dispersed solid material with a large surface area. Its microporous surface possesses the characteristics required for catalytic activity, such as adsorption performance, surface activity, and excellent thermal stability. Therefore, it is widely used as a catalyst and catalyst carrier for chemical reactions. Spherical activated alumina pressure swing oil adsorbent is a white spherical porous particle with uniform particle size, smooth surface, high mechanical strength, strong moisture absorption, and no swelling or cracking after water absorption. It is non-toxic, odorless, and insoluble in water and ethanol. Activated alumina is an efficient desiccant for deep drying of trace amounts of water. Very suitable for non thermal regeneration devices.
Activated alumina is an inorganic substance with excellent performance. It can not only be as a dehydration adsorbent and chromatographic adsorbent, but more importantly, as a carrier. Activated alumina carriers are widely uses in the petrochemical industry, involving various reactions such as reforming, hydrogenation, dehydrogenation, dehydration, etc.
Activated alumina carrier is a spherical porous material that is odorless, non powdering, insoluble in water and ethanol. It is through special processes and has a unique skeleton structure, which makes it highly affinity for active components. The micropores of the activated alumina carrier are evenly distributed, with suitable pore size, large pore volume, high water absorption rate, low bulk density, good mechanical properties, and good stability. It is suitable for use as a carrier and has the characteristics of good low-temperature activity, wide operating temperature range, and short vulcanization time.
