The invention relates to a method for suspension hydrogenation of an anthraquinone compound of a mixture comprised of two or more anthraquinone compounds in a reactor containing the working solution and the one additional gas phase which contains hydrogen. At least one catalyst is suspended in said working solution. The working solution and the gas phase are at least partially fed into the reactor through a device with openings or channels whose hydraulic diameter is between 0.5 and 20 mm, preferably between 1 and 10 mm, and more preferably between 1 and 3 mm.
L'invention concerne un procédé d'hydrogénation en suspension d'un composé anthraquinone ou d'un mélange de deux de ces composés ou plus dans un réacteur, qui contient la solution préparée dans laquelle un catalyseur est en suspension et qui contient en outre une phase gazeuse comprenant de l'hydrogène. La solution préparée et la phase gazeuse sont guidées dans le réacteur, au moins en partie à travers un dispositif comportant des ouvertures ou des canaux, dont le diamètre hydraulique se situe entre 0,5 et 20 mm, de préférence entre 1 et 10 mm, de préférence entre 1 et 3 mm.
