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 lot of micropores. It has many of 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 (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 vapor from lubricating oil polluted by oxygen, hydrogen gas, carbon dioxide and natural gases. It can also serve as a catalyst, catalyst carrier, and chromatographic analysis carrier.
It is used for defluorinating drinking water that contains high levels of fluorine, for defluorinating circulating alkanes to produce alkylbenzene in transformer oil, for deacidification regeneration in textile and electronics industries, for gas drying in the oxygen and textile industry. 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 non-heat regenerative devices.
Activated Alumina is a material with a large surface area. It also has many surface properties, including a wide range of pore structure and distribution. 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 differing requirements in terms of physical structure. Statistically, the amount that alumina is used as carriers and catalysts exceeds the total amount of catalysts used in silica, activated carbon and diatomaceous soil. This shows alumina’s central role in carriers and catalysts.
