Title (EN) A RISER REACTOR SYSTEM AND A PROCESS FOR THE PREPARATION OF AN OLEFINIC PRODUCT
(FR) SYSTÈME DE RÉACTEUR À COLONNE MONTANTE ET PROCESSUS DE PRÉPARATION D'UN PRODUIT OLÉFINIQUE
Abstract:
(EN) A riser reactor system comprising a riser reactor and a catalyst feed device for fluidized catalyst, the riser reactor having a riser interior in which catalyst is flowing during normal operation, and the feed device comprising an annular trough surrounding the riser interior, the annular trough having an upstream opening for receiving fluidized catalyst, and at least one substantially circumferential downstream opening providing fluid communication between the trough and the riser interior; and a process for the preparation of an olefinic product using a riser reactor system as claimed in any one of the preceding claims, the process comprising reacting an oxygenate feedstock in the presence of an oxygenate conversion catalyst under oxygenate-to-olefin conversion conditions in the riser reactor system, to obtain the olefinic product.
(FR) L'invention porte sur un système de réacteur à colonne montante comprenant un réacteur à colonne montante et un dispositif d'apport de catalyseur pour catalyseur fluidisé. Le réacteur comporte une colonne montante où le catalyseur s'écoule en fonctionnement normal, et un dispositif d'apport comprenant une trémie annulaire entourant l'intérieur de la colonne montante. Ladite trémie présente une ouverture amont recevant le catalyseur fluidisé, et au moins une ouverture aval sensiblement ronde reliant la trémie à l'intérieur de la colonne montante. L'invention porte également sur un processus de préparation d'un produit oléfinique utilisant un système de réacteur à colonne montante, et consistant à faire réagir un apport d'oxygénat en présence d'un catalyseur de conversion de l'oxygénat dans des conditions permettant la conversion oxygénat vers oléfine dans le réacteur à colonne montante pour obtenir le produit oléfinique.
