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 size particles, a high mechanical resistance, hygroscopicity and does not crack or swell after absorbing the water. It is non-toxic and odorless. 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, liquid moisture and water vapor 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 in a variety of industries, including the textile and electronics industries, the oxygen industry and petrochemical drying. 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 dew point is -55. It is an effective 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 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 both a specialty chemical and fine chemical. Its high specificity, as well as its many grades and varieties, is due to the fact that different applications have varying requirements in terms of physical structure. Statistically, alumina’s use as carriers and catalysts is greater than the total amount used for catalysts such as molecular silt, activated carbons, diatomaceous and silica-alumina gel. This shows alumina’s central role in carriers and catalysts.
