Fluid catalytic cracking process comprising the steps of (a) preparing a physical 5 mixture comprising (i) aluminium trihydrate and/or flash-calcined aluminium trihydrate and (ii) a divalent metal oxide, hydroxide, carbonate, or hydroxycarbonate, (b) shaping the physical mixture of step a) to form fluidisable particles, and (c) adding the fluidisable particles obtained from step b) or step c) to a fluid catalytic cracking unit. In this FCC process, active sites of the catalyst composition are formed in-situ, i.e. in the FCC unit, without requiring peptisation, aging, or calcination steps prior to the addition of the composition to the hydrocarbon conversion unit.
L'invention porte sur un procédé de craquage catalytique fluide qui consiste à: (a) préparer un mélange physique comprenant (i) un trihydrate d'aluminium et/ou un trihydrate d'aluminium calciné instantanément et (ii) un oxyde métallique divalent, un hydroxyde, un carbonate ou un hydroxycarbonate, (b) former le mélange physique de l'étape a) pour obtenir des particules fluidisables, et (c) ajouter les particules fluidisables obtenues à l'étape b) ou à l'étape c) à une unité de craquage catalytique fluide. Dans ce procédé de craquage catalytique fluide, des sites actifs de la composition de catalyseurs sont formés in-situ, c'est-à-dire dans l'unité de craquage catalytique fluide, sans avoir à effectuer une peptisation, un vieillissement ou une calcination avant d'ajouter la composition à l'unité de conversion d'hydrocarbures.
