Title (EN) PENTASIL CATALYST FOR LIGHT OLEFINS IN FLUIDIZED CATALYTIC UNITS
(FR) CATALYSEUR À BASE DE ZÉOLITE DE TYPE PENTASIL POUR LA PRODUCTION D'OLÉFINES LÉGÈRES DANS DES UNITÉS DE CRAQUAGE CATALYTIQUE À LIT FLUIDISÉ
Abstract:
(EN) The catalyst of this invention is capable of enhancing light olefin, e.g., propylene, yields in fluidizable catalytic cracking (FCC) processes. The catalyst comprises (a) pentasil zeolite, (b) at least 5% by weight phosphorus (P2O5) based on particles containing the pentasil, and at least about 1% by weight iron oxide, as measured by Fe2O3, outside of the pentasil zeolite's framework. The catalyst is fluidizable and has an average particle size in the range of about 20 to about 200 microns. The catalyst composition can further comprise additional zeolite suitable for cracking hydrocarbons in a FCC process. The catalyst has been shown to be highly active compared to other catalysts and shows a high selectivity for propylene produced in an FCC process.
(FR) La présente invention concerne un catalyseur permettant d'accroître la production d'oléfines légères, par exemple de propylène, dans des procédés de craquage catalytique à lit fluidisé (FCC). Le catalyseur comprend (a) une zéolite de type pentasil, (b) au moins 5 % en poids de phosphore (P2O5) sur la base des particules contenant la zéolite de type pentasil et au moins environ 1 % en poids d'oxyde de fer, en quantité de Fe2O3, à l'extérieur du squelette de la zéolite de type pentasil. Le catalyseur peut être fluidisé et a une taille moyenne des particules comprise dans l'intervalle d'environ 20 à environ 200 microns. La composition de catalyseur peut en plus comprendre une zéolite supplémentaire convenant pour le craquage d'hydrocarbures dans un procédé de FCC. Le catalyseur s'est avéré extrêmement actif par rapport aux autres catalyseurs et il présente une sélectivité élevée pour le propylène produit dans un procédé de FCC.
