Title (EN) PROCESS AND APPARATUS FOR FLUID CATALYTIC CRACKING OF HYDROCARBONS
(FR) PROCEDE ET DISPOSITIF DE CRAQUAGE CATALYTIQUE FLUIDE D'HYDROCARBURES
Abstract:
(EN) It has been discovered that when a zirconium compound, preferably an acetate or other oil-soluble organic Zr compound, is utilized in an FCC riser, it must be injected into a low temperature stream, e.g., a feed stream, or preferably injected directly into the riser, e.g., through a quill, so that any thermal decomposition occurs in the riser in proximity to the FCC conversion catalyst. Water solutions prematurely decompose, depositing Zr on piping of the cracking process unit.
(FR) On a découvert que lorsque l'on utilise un composé à base de zirconium, de préférence, un acétate ou un autre composé Zr organique soluble dans l'huile, dans un élévateur de catalysateur de craquage catalytique fluide, on doit injecter ce composé dans un courant basse température, par exemple, un courant d'alimentation, ou on doit préférablement l'injecter directement dans l'élévateur de catalyseur, par exemple à travers une buse, de manière à ce que toute décomposition thermique s'effectue dans cet élévateur, à proximité du catalyseur de conversion de craquage catalytique fluide. Des solutions aqueuses se décomposent prématurément, déposant du zirconium sur les canalisations de l'unité de traitement par craquage.
