What activates alumina?
Activated Alumina is also called activated alu, which contains alumina as the 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. They also exhibit a strong hygroscopicity. After absorbing water it does not expand or contract 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.
Uses of activated allumina
Activated alu is classified under the chemical category. It’s used primarily 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 times of adsorption and resurrection. You can use it as a desiccant. It also has the ability to absorb the vapor of natural gas from polluted oxygen and hydrogen. It is also a catalyst carrier, and can be used to carry out chromatographic analysis.
This agent can be used to defluorinate high-fluorine drinking waters (large fluorine elimination capacity), for alkane circulating in the production process of alkylbenzene and for deacidification regenerator transformer oil. 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). This is an effective desiccant to dry trace water. 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 catalysts or adsorbents.
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, activated charcoal, diatomaceous Earth, molecular sieve and silica-alumina gel. This highlights the crucial role played by alumina when it comes to catalysts and carriers.
