The invention relates to a method for carrying out gas-liquid reactions in a flow reactor (1) having several parallel reactor chambers (8) which are open in the direction of flow. Space-time yield can be increased by using a reactor having at least three chambers whose ratio of chamber width b to slot width s on average is greater than 3, where the slot width s is between 5 and 100 mm, s is preferably between 5 and 50 mm and s/b is between 5 and 100. The flow reactor provided for by the invention, which comprises at least three chambers (8) and presents the above ratio s/b, is preferably tubular and contains one or more plate stacks (5). The above method is suitable for the production of hydrogen peroxide in accordance with the anthraquinone method, using a suspension--hydrogenation catalyst.
L'invention concerne un procédé permettant de conduire des réactions gaz-liquide dans un réacteur à écoulement (1) présentant plusieurs chambres de réaction (8) parallèles et ouvertes dans le sens d'écoulement. Pour augmenter le rendement, on utilise un réacteur comprenant au moins trois chambres de réaction (8) dans le rapport b/s (b = largeur de chambre; s = largeur de fente s) est en moyenne supérieure à 3, la largeur de fente s étant comprise entre 5 et 100 mm. De préférence, la largeur de fente s est comprise entre 5 et 50 mm et le rapport s/b entre 5 et 100. Le réacteur à écoulement (1) selon l'invention comprend au moins trois chambres de réaction (8) et le rapport mentionné s/b est, de préférence, tubulaire et contient au moins une pile de plaques (5). Ce procédé s'adapte à la production de peroxyde d'hydrogène selon le procédé d'anthraquinone à l'aide d'une suspension catalyseur d'hydrogénation.
