Zusammenfassung:A method for providing a reactor at least partially filled with a reactant mass, comprising the steps of a. providing a reactor that has an inner volume, wherein the reactor comprises i. at least one agitation means, preferably located in a first zone of the inner volume; ii. at least one liquid-solid separation means, wherein the at least one liquid-solid separation means A. comprises at least one outlet that is at least partially closed, and B. is located in the inner volume, preferably in a further zone of the inner volume; b. at least partially filling the inner volume with a first mixture, wherein i. the volume of the first mixture defines a pre-reactant mass, and ii. the first mixture comprises A. a particulated porous catalyst, and B. a first liquid; c. agitating the first mixture in the inner volume with the at least one agitation means, i. thereby obtaining a circulation of the first mixture in the inner volume, ii. wherein A. preferably a surface loading rate of the first mixture through the at least one liquid-solid separation means is V1, B. preferably a temperature in the inner volume is T1, and C. preferably a pressure in the inner volume is P1; d. at least partially opening the at least one outlet to allow at least a partial volume of the first mixture to exit the inner volume through the at least one outlet, i. thereby obtaining the reactant mass, wherein the reactant mass is defined as the volume of the first mixture remaining in the inner volume, and ii. wherein preferably the surface loading rate of the first mixture through the at least one liquid-solid separation means is V2. L'invention concerne un procédé pour fournir un réacteur au moins partiellement rempli d'une masse de réactif, comprenant les étapes consistant à : a. fournir un réacteur qui présente un volume interne, le réacteur comprenant i. au moins un moyen d'agitation, de préférence situé dans une première zone du volume interne ; ii. au moins un moyen de séparation liquide-solide, l'au moins un moyen de séparation liquide-solide A. comprenant au moins une sortie qui est au moins partiellement fermée, et B. étant situé dans le volume interne, de préférence dans une autre zone du volume interne ; b. remplir au moins partiellement le volume interne avec un premier mélange, i. le volume du premier mélange définissant une pré-masse de réactif, et ii. le premier mélange comprenant A. un catalyseur poreux particulaire, et B. un premier liquide ; c. agiter le premier mélange dans
