not available for EP105135of corresponding document:A process for the manufacture of hydrogen peroxide by the anthraquinone process is improved by carrying the hydrogenation step in a conventional hydrogenation reactor containing a fixed bed hydrogenation catalyst and passing a foamed mixture of the anthraquinone-containing working solution and the hydrogenating gas downwards through the catalyst bed without using a diffuser, spray nozzle or other special device for forming the foam. The hydrogenaing gas may be a mixture of hydrogen and an inert gas such as nitrogen, a rare gas, carbon dioxide or a fluorinated gas.
