In addition to absorbing the alkali in the working liquid, activated alumina has a strong regeneration ability to the hydride degradation, which can convert the increased degradants in the hydrogenation reaction into effective anthraquinone, ensuring the stability of the total effective anthraquinone, which is conducive to the oxidation reaction, reducing the addition of anthraquinone, and saving the operating cost.At the same time, considering the need of regeneration, avtivated alumina is used to ensure good mechanical properties of hydrogen peroxide, and the activity changes little after regeneration.

Aluminum oxide used for catalyst or catalyst support has certain requirements in terms of physical properties and structure.

The most basic features are specific surface area, pore structure, crystal structure, etc. For example, the reforming catalyst is the precious metals platinum and rhenium supported on γ-Al2O3 or η-Al2O3. The structure of AL2O3 has a great influence on the reaction activity. When it is loaded on other forms of aluminum oxide, its activity is very low.

We hope that all of our leading Activated Alumina for Absorption in Producing Hydrogen Peroxide (H2O2) can have a positive impact on society and the environment while growing and creating value. We have many years of production experience and have withstood the test of the market. With the joint efforts of all staff, we will continue to strengthen the exchange and cooperation with domestic and foreign industrial partners.
