Abstract
Description
La présente addition concerne l'utilisation d'un catalyseur de type aluminosilicate comprenant une zéolithe de structure MFI, synthétisée en milieu fluorure, contenant du silicium, de l'aluminium, et du gallium, dans les réactions d'aromatisation des coupes légères contenant en majeure partie 2 atomes de carbone par molécule en présence d'olefines, et de gaz inertes tels que le méthane, l'azote, l'oxyde de carbone et l'hydrogène. L'aromatisation est effectuée dans au moins un réacteur à lit circulant de catalyseur. I1 convient alors que le catalyseur soit utilise sous forme de billes. The present addition relates to the use of a catalyst of the aluminosilicate type comprising a zeolite with an MFI structure, synthesized in a fluoride medium, containing silicon, aluminum, and gallium, in the aromatization reactions of light cuts containing in mainly 2 carbon atoms per molecule in the presence of olefins, and inert gases such as methane, nitrogen, carbon monoxide and hydrogen. The aromatization is carried out in at least one reactor with a circulating catalyst bed. It is then advisable for the catalyst to be used in the form of beads.
La présente addition concerne également l'utilisation en aromatisation de coupes à forte teneur en C2 (éthane et éthylène) d'un catalyseur du type aluminosilicate de composition suivante exprimée en poids a) 0,01 à 10 % en poids de gallium, de préférence 0,3 à 7 %, b) 0,1 à 99,49 % (et de préférence 10 à 40 %) d'une matrice choisie
dans le groupe formé par l'alumine, la silice, la magnésie, une
argile et toute combinaison d'au moins deux des composés précites
et c) 0,50 à 99, 89 % (et de préférence 60 à 90 %) d'une zéolithe
synthétique en milieu fluorure de formule chimique approchée
généralement la suivante
M2/nO, A1203, xSi02, où
M représente un proton et/ou un cation métallique
n est la valence du cation
x est un nombre compris entre 12 et 1000 (rapport molaire
Si02/A1203), la zéolithe ayant une teneur en fluor comprise entre
0,01 et 1,5 % en poids, de préférence 0,1 à 1 % en poids, le fluor
étant incorporé lors de la synthèse, la dite zéolithe étant aussi
caractérisée par un diagramme de diffraction X présenté dans le
tableau 1 du brevet principal.The present addition also relates to the use in aromatization of cuts with a high C2 content (ethane and ethylene) of a catalyst of the aluminosilicate type of the following composition expressed by weight a) 0.01 to 10% by weight of gallium, preferably 0.3 to 7%, b) 0.1 to 99.49% (and preferably 10 to 40%) of a chosen matrix
in the group formed by alumina, silica, magnesia, a
clay and any combination of at least two of the above compounds
and c) 0.50 to 99.89% (and preferably 60 to 90%) of a zeolite
synthetic in fluoride medium with approximate chemical formula
usually the following
M2 / nO, A1203, xSi02, where
M represents a proton and / or a metal cation
n is the valence of the cation
x is a number between 12 and 1000 (molar ratio
Si02 / A1203), the zeolite having a fluorine content of between
0.01 and 1.5% by weight, preferably 0.1 to 1% by weight, fluorine
being incorporated during the synthesis, the so-called zeolite being also
characterized by an X-ray diffraction diagram presented in the
Table 1 of the main patent.
En utilisant les techniques de la présente addition on a constaté des sélectivités en aromatiques très stables dans des conditions longues de fonctionnement de l'ordre de 500 heures et plus selon les conditions opératoires utilisées. Using the techniques of the present addition, very stable aromatics selectivities have been found under long operating conditions of the order of 500 hours or more depending on the operating conditions used.
