ABSTRACT:
The invention relates to a process for the production of hydrogen peroxide by the anthraquinone process. A reaction mixture into which there are fed hydrogen or a hydrogen-containing gas and a working solution, i.e. an anthraquinone derivative in an organic solvent, is circulated via a tubular static mixing zone (9) which is continuous or comprises several parts, in order to hydrogenate the anthraquinone derivative in the presence of a solid catalyst, and by removing hydrogenated working solution (13) and gas (11) from the circulating reaction mixture (8). According to the invention, the reaction mixture (14) is circulated (8) via a catalyst-coated static mixing zone (9), where it is simultaneously both mixed and catalyzed.
