CA 2561024

A preferred embodiment of a system for loading catalyst and/or additives into a fluidized catalytic cracking unit includes a bin for storing at least one of the catalyst and/or additives, and a loading unit in fluid communication with the storage bin and the fluidized catalytic cracking unit on a selective basis. The loading unit is capable of being evacuated so that a resulting vacuum within the loading unit draws the catalyst and/or additive from the bin. The loading unit is also capable of being pressurized so that the catalyst and/or additive is transferred from the loading unit to the fluidized catalytic cracking unit.

Selon une forme d'exécution préférée, un système de chargement de catalyseur et/ou d'additifs dans une unité de craquage catalytique en lit fluidisé comprend un réservoir pour le stockage d'au moins un catalyseur et/ou d'additifs et une unité de chargement en communication fluidique avec le réservoir et l'unité de craquage catalytique en lit fluidisé sur une base sélective. Il est possible de faire le vide dans l'unité de chargement de sorte que le vide généré dans celle-ci aspire du réservoir le catalyseur et/ou l'additif. Il est également possible de mettre sous pression l'unité de chargement de sorte que le catalyseur et/ou l'additif soit transféré de l'unité de chargement à l'unité de craquage catalytique en lit fluidisé.
