The present invention relates to a process for intro-ducing a solid catalyst particle feed into a fluidised or ag-itated vessel (14) utilising a feed delivery device (1), a vertical feed dilution pipe (3) and a feed injection pipe (6) connected to the vessel (14), said process comprising the steps of: (a) introducing the solid catalyst particles feed from the feed delivery device (1) into the vertical feed di-lution pipe (3), (b) diluting the solid catalyst particles feed by letting the solid particle reaching by gravity their ter-minal velocity in the feed dilution pipe (3), (c) introducing the diluted solid catalyst particles feed into the injection pipe (6) and mixing it with conveying gas, and introducing said gas conveyed diluted solid catalyst particles feed into the vessel (14). The present invention relates to a process for introducing a solid catalyst particle feed into a fluidised or agitated vessel (14) utilising a feed delivery device (1), a vertical feed dilution pipe (3) and a feed injection pipe (6) connected to the vessel (14), said process comprising the steps of: (a) introducing the solid catalyst particles feed from the feed delivery device (1) into the vertical feed di-lution pipe (3), (b) diluting the solid catalyst feed by letting the solid particle reaching by gravity their terminal veloc-ity in the feed dilution pipe (3), (c) introducing the diluted solid catalyst particles feed into the injection pipe (6) and mixing it with a conveying gas, and introducing said gas conveyed diluted solid catalyst particles feed into the ves-sel (14).
L'invention concerne un procédé permettant d'introduire une charge particulaire de catalyseur solide dans une cuve fluidisée ou en mouvement (14) en utilisant un dispositif d'alimentation (1), un tuyau vertical de dilution de charge (3) et un tuyau d'injection de charge (6) reliés à la cuve (14). Ce procédé consiste: (a) à introduire les particules de catalyseur solide issues du dispositif d'alimentation (1) dans le tuyau vertical de dilution de charge (3), (b) à diluer la charge particulaire de catalyseur solide en laissant les particules solides atteindre par gravité leur vitesse terminale dans le tuyau de dilution de charge (3), (c) à introduire les particules de catalyseur solide diluées dans le tuyau d'injection (6), à les mélanger avec un gaz de transport, et à introduire dans la cuve (14) cette charge particulaire de catalyseur solide diluée transportée par un gaz.
