What is activated aluminum?

Activated Alumina also known as “activated” alumina is often referred to simply as “activated”, as it uses alumina as the catalyst. It is porous and high-dispersion material that has a lot of micropores. 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 uniform particle size. It also has a smooth surface. 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 (adsorbents), catalysts, and carrier catalysts. 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 of lubricating from oxygen, hydrogen and carbon dioxide. It can be used both as a catalyst and catalyst carrier, and also as a chromatographic analyzer.

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, textile and oxygen industries. The dew point of the product can reach as low as -40 degrees Celsius. In other industries, such chemical fertilizer drying, petrochemical dehydration, and air separation, it can reach up to -55 degrees Celsius. It is a desiccant that can be used to dry out trace water. It is a great choice for devices without heat.

Activated Alumina is characterized by a large surface area, diverse pore structure and distribution of pore size, as well as rich surface properties. It is used in many different 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, the amount alumina used for carriers and catalysts is greater than the total amount used of catalysts found in silica, activated carbon and diatomaceous soil. This demonstrates the central role of alumina when it comes to catalysts and carriers.
