What is activated aluminum?

Activated Alumina also known as activated, is often referred as “activated” alumina which uses alumina for the catalyst. It is porous and high-dispersion material that has a large amount of surface area. The surface is characterized by the properties required for catalysis such as excellent thermal stability, adsorption, and surface activity. Spherical activated aluminum pressure swing oil adsorbent consists of white, spherical particles. The activated aluminum has a smooth surface with uniform particle size. It is also strong in mechanical strength and hygroscopicity. It does not crack or swell after absorbing the water and it remains in its initial state. The activated alumina can effectively dry out trace water. It is suitable for heatless regeneration equipment.

Uses for activated alumina

The main uses of activated alumina are in water purifiers. The adsorption of gas, water vapour and some liquid humidity is possible with activated alumina. It is possible to revive the adsorption by heating between 175315°C in order to remove any remaining water. You can perform the adsorption process and resurrection multiple times. As well as being used for desiccants, it can absorb the vapors from lubricating oil polluted with oxygen, hydrogen or carbon dioxide. It can also serve as a catalyst, catalyst carrier and chromatographic analysis carrier.

It can be used for defluorinating drinking water that contains high levels of fluorine, for defluorinating circulating alkanes to produce alkylbenzene or for deacidification regeneration for transformer oil. Also, it is used for gas drying in the electronics industry, the textile industry and the oxygen industry. The dew point of the product can reach as low as -40 degrees Celsius. In the chemical fertilizer industry, the dew point is -40, while in the petrochemical and air separation industries, the dewpoint reaches -55. It is a desiccant that can be used to dry out trace water. It is a great choice for non-heat regenerative devices.

Activated Alumina is characterized by a large surface area, diverse pore structure and distribution of pore sizes, as well as rich surface properties. Activated alumina is used in many applications, including adsorbents.

Alumina used as an adsorbent or catalyst carrier is a specialty chemical. Its high specificity, as well as its many grades and varieties, is due to the fact that different applications have different physical requirements. Statistically, alumina is used more as a catalyst and carrier than all the catalysts found in silica, activated carbons, diatomaceous, and molecular sift. This shows alumina’s central role in carriers and catalysts.
