A process for production of hydrogen peroxide by the AO-process which comprises the following steps: (a) hydrogenation of a working solution comprising at least one quinone compound selected from anthraquinone (AQ) and its derivatives to obtain at least one corresponding hydroquinone compound; (b) oxidation of said at least one hydroquinone compound to obtain hydrogen peroxide; and (c) extraction of said hydrogen peroxide, during and/or subsequently to said oxidation step; wherein the AO-process is characterized in that the hydrogenation of the at least one quinone compound is performed by mixing a working solution comprising the quinone compound with hydrogen or a hydrogen containing gas in one or more mini-channel reactors; and/or the oxidation of the at least one hydroquinone compound is performed by mixing a working solution comprising the hydroquinone compound with oxygen or an oxygen containing gas in one or more mini-channel reactors; and further characterized in that the AO-process using at least one of the said mini-channel reactors in the hydrogenation (a) and/or in the oxidation (b) is adapted to obtain an aqueous hydrogen peroxide solution which is at least partially ready to be used on the same industry site as the said AO-process, either directly after resulting from the extraction (c) or optionally after a storage on the same site, in another industrial process on the said industry site which involves the use of an aqueous hydrogen peroxide. |
