PROCESS FOR THE MANUFACTURE OF HYDROGEN PEROXIDE

摘要

A process is disclosed concerning the manufacture of hydrogen peroxide by the so-called anthraquinone process (AO-process), and in particular concerning the improvement of an essential process step of said AO-process, i.e. an improvement of the hydrogenation step. The inventive hydrogenation step of the AO-process is carried out in a conventional hydrogenation reactor containing a fixed bed of the hydrogenation catalyst by passing a foaming mixture, which is formed of the anthraquinone containing working solution and the hydrogenating gas, downwards through the fixed-bed catalyst.
