Abstract

La présente invention a pour objet la découverte d'un moyen pour minimiser le temps pendant lequel un catalyseur et des produits gazeux sont en contact en sortie de l'orifice de décharge (22) d'un conduit de réacteur (10). Le conduit de réacteur débouche dans une chambre de séparation (24) directement reliée à un séparateur (32). Un pied plongeant (34) du séparateur est directement relié à la chambre de séparation ou à une chambre intermédiaire (64) qui communique directement avec la chambre de séparation. De ce fait, le catalyseur ne peut jamais être entraîné dans le grand volume ouvert de la cuve de réacteur. Par conséquent, un catalyseur échappé hors de la chambre de séparation est rapidement renvoyé dans la chambre de séparation, ce qui minimise le temps pendant lequel le catalyseur et les produits gazeux sont en contact après avoir été évacués du conduit de réacteur.
