CANADIAN PATENT APPLICATION OF THOMAS BERGLIN and WOLFGANG HERRMANN FOR A METHOD IN THE PRODUCTION OF HYDROGEN PEROXIDE Abstract of the Disclosure: A method in the production of hydrogen peroxide is described, utilising the so-called anthraquinone process in which alkylated anthraquinones dissolved in organic solvents to form a liquid working solution, are alternately reduced and oxidised. The working solu- tion is subjected to catalytic hydrogenation by con- tacting it with hydrogen in the presence of a hydro- genation catalyst. The contact with hydrogen is establish- ed in a fixed catalyst bed comprising one or more solid catalyst bodies, each of which consists of a thin-walled, coherent, solid body of a structure forming parallel 1a channels through which the working solution and hydrogen gas are allowed to pass. The channels of the catalyst bed are of equal length and parallel to the direction of flow of the working solution. The catalyst preferably is provided in a thin layer on the walls of the struc- ture, preferably by means of a porous carrier. 1b
