Fixed Bed Process Hydrogen Peroxide

There are several methods for hydrogen peroxide production and manufacturing, among them the AO(auto-oxidation) process is the most prevailing one. In this process, 2-alkyl anthraquinone is mixed with organic solvent to make up the working solution, which is hydrogenated in presence of catalyst, and the resulting is oxidized by air (or oxygen) in counter-current way before being extracted, regenrated, purified and enriched to get commercial hydrogen peroxideproduct. Depending upon the different reactor type in the hydrogenation unit, AO process is further divided into Fixed Bed Reactor Process and Fluidized Bed Reactor Process. 


Introduction of Anthraquinone Method

At present, the industrial production of hydrogen peroxide in the world basically uses anthraquinone method (this method was started by DuPont Company in 1953), which takes alkyl anthraquinone as the working carrier.

In China, 2-ethyl anthraquinone(EAQ)is mainly used as the working carrier. Dissolve EAQ in organic solvents(generally composed of heavy aromatics and trioctyl phosphate (TOP) in certain proportion) to form working fluids, hydrogenation and oxidation are then carried out under the action of catalyst (palladium catalyst) to produce hydrogen peroxide (H2O2) and H2O2 is extracted from the working fluid with pure water to obtain hydrogen peroxide with H2O2 content of 27.5%, which is concentrated and reprocessed into other specifications.
