What is activated aluminum?
Activated Alumina also known as “activated” alumina is often referred to simply as “activated”, as it 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. The white spherical adsorbent particles of spherical activated aluminum are porous. 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 does not smell. 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 175 and 315°C. 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 be used both as a catalyst and catalyst carrier, and also as a chromatographic analyzer.
It can be used in a variety of industries, including the oxygen, textile and electronics industries, to dry gas. The dew point of the product can reach as low as -40 degrees Celsius. In the chemical fertilizer industry, petrochemical dryers, and other industries, it can also be used to purify and desiccate. It is a desiccant that can be used to dry out trace water. It is a great choice for devices without heat.
The activated alumina is characterized by a large surface area, diverse pore structure and distribution of pore sizes, 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, diatomaceous, activated carbon and molecular sift. This shows alumina’s central role in carriers and catalysts.
