The fluidized bed hydrogen peroxide process of Liming Institute has been demonstrated

On July 30, the 20,000 tons/year (concentration is calculated as 27.

According to Zhao Xiaodong, compared with the fixed bed process, the fluidized bed hydrogenation process has the advantages of uniform gas-liquid-solid three-phase mixing, high mass transfer efficiency, and low consumption of anthraquinone.

Industry experts believe that the fluidized bed hydrogen peroxide process and key raw materials with domestic independent intellectual property rights developed by Liming Institute, especially the preparation process of powder palladium catalyst, are of great significance to promoting the technological progress of the hydrogen peroxide industry

In the process of research and development, after more than 30 years, Liming Institute has completed the small test, the pilot test and the expansion test, and finally developed the fluidized bed hydrogen peroxide process, and localized all the key raw materials

Zhao Xiaodong said that the technology uses a new high-efficiency working fluid system composed of 2-amyl anthraquinone and diisobutyl methanol, which increases the hydrogenation efficiency to more than 15 grams per liter

At present, Liming Institute has prepared a complete process package for fluidized bed hydrogen peroxide, and has large-scale production capacity such as powder alumina palladium catalyst for fluidized bed hydrogenation, 2-amyl anthraquinone, and diisobutyl methanol.

"In the next step, the newly built hydrogen peroxide unit of Liming Institute will develop in the direction of large-scale, high-efficiency and automation
