Anthraquinone-based fixed bed production of hydrogen peroxide

Anthraquinone-based fixed bed production of hydrogen peroxide

The production of hydrogen peroxide by anthraquinone is currently one of the most mature production methods in the world, and manufacturers at home and abroad are basically The anthraquinone process is used to produce hydrogen peroxide. The process involves the preparation of a working solution of 2-alkyl anthraquinone and an organic solvent. Under certain conditions of temperature, pressure and catalyst, the anthraquinone in the working solution is hydrogenated with hydrogen to produce a hydrogenated anthraquinone solution (hydrogenated solution), which is then The hydrogenated solution is then oxidized with air (or oxygen) to produce hydrogen peroxide and anthraquinone solution (oxidation solution). The hydrogen peroxide solution is extracted and separated to produce the hydrogen peroxide solution, and the extracted working solution is treated and recycled. In the production of hydrogen peroxide by anthraquinone, the choice of catalyst, working solution and anthraquinone hydrogenation process is most critical. The choice of catalyst, working fluid and anthraquinone hydrogenation process is the most critical.
