General

Hydrogen peroxide is a kind of environment-conscious product. Its production adopts anthraquinone palladium catalyst fixed bed hydrogenation process which includes below parts: hydrogenation, oxidation, extraction and purification, post-treatment, makeup, and concentration.

In the presence of the Pd catalyst, the alkyl anthraquinone dissolved in the organic solvent is hydrogenated to produce the alkyl anthrax-hydroquinone, which is oxidized to get the hydrogen peroxide under given reaction conditions eventually.

Meanwhile, the alkyl anthrax-hydroquinone is converted into alkyl anthraquinone and the stream of working solution contained H2O2. The resulting stream of working solution is fed to the extraction column for extraction by using demineralized water as extracting agent in a counter-current flow to produce H2O2, which is purified to form the finished product-H2O2 and it will be delivered to the storage tank.

The solution of alkyl anthraquinone after treatment returns to the hydrogenation section for reuse.
