Activated Alumina and Uses |

What activates alumina?

Activated Alumina is also called activated alu, which contains alumina in its catalyst. The material is porous and high-dispersion, with large surfaces and micropores. Because of its excellent surface properties, which include excellent thermal stability and adsorption performance as well as surface activity, it can be used for catalysts as well as catalyst carriers for chemical reactions. The sphere activated alumina pressure-swing oil adsorbent contains white, spherical and porous particles. The smooth, uniformly sized particles of activated aluminum have high mechanical strength and strong hygroscopicity. After absorbing water it does not shrink or crack and is non-toxic. High-efficiency activated alumina desiccant is used for the deep drying and removal of trace water. It can also be used for heating-free regeneration.

Utilisations of activated aluminum:

Activated alu is classified under the chemical category. It’s used mainly in catalysts, water purifiers as well as in catalyst carriers and catalysts. Activated allumina can selectively absorb water vapor, liquid moisture and gas. Once the adsorption has become saturated, you can heat it to 175315 in order to get rid of water. You can perform multiple rounds of adsorption and resurrection. You can use it as a desiccant. It also has the ability to absorb the vapors of natural gas and polluted oxygen. It is also a catalyst and carrier, and can be used for chromatographic analysis.

This agent can be used to defluorinate high-fluorine beverages (large fluorine elimination capacity), for alkane production, deacidification, regenerator and gas drying agent for electronics, the textile and oxygen industries. Automatic instrument wind drying. This is used to desiccate and purify chemical fertilizer, petroleum drying and other industries. (The dewpoint can reach 40, while the pressure swing absorb dewpoint can reach 55 in the industry of air separation). It can be used to dry trace amounts of water in a deep manner. It can be used to make non-heat regenerators.


The specific surface area of activated alumina is large, it has rich surface properties and can be distributed in a wide variety of pore shapes and sizes. This makes it a versatile material that can be used as catalyst carriers, adsorbents or catalyst carriers.


The use of alumina as an adsorbent or catalyst carrier is one example of a unique chemical. Because different applications require different properties, alumina has a high specificity. There is also countless grades. Statisticians have shown that the amount of alumina used to catalyze and transport catalysts is greater than the combined amount of catalysts in silica ge, activated charcoal, diatomaceous Earth, molecular sieve and silica allumina gel. This illustrates the central role of alumina as a catalyst and carrier.
