What is activated aluminum?

Activated Alumina also known as “activated” alumina is often referred to simply as “activated”, 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. The white, spherical particles of spherical activated aluminum pressure swing oil adsorbent are porous. 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.

Activated alumina uses:

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 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 of lubricating from oxygen, hydrogen and carbon dioxide. It can also serve as a catalyst, catalyst carrier, and chromatographic analysis carrier.

This agent can be used for defluorinating drinking water that contains high levels of fluorine, for defluorinating circulating alkanes for the production alkylbenzene and for deacidification regeneration for transformer oils. It can also be used for gas drying in the electronics industry, the textile industry and the oxygen industry. 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 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. 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 differing requirements in terms of physical structure. 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 illustrates the central role of alumina when it comes to catalysts and carriers.
