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, high mechanical resistance, good 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 of 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 lubricating oil vapor from polluted hydrogen, oxygen, carbon dioxide and natural gas. 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 a gas-drying agent in the electronics, textile and oxygen industries. 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 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 size, as well as rich surface properties. Activated alumina is used in many 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 different physical requirements. Statistically, the amount used to make alumina catalysts and carriers exceeds the total amount used in silica, activated carbon and diatomaceous soil. This shows alumina’s central role in carriers and catalysts.
