Abstract

L'invention concerne un procédé de craquage catalytique fluidisé, dans lequel on met en contact une charge d'hydrocarbure avec un catalyseur de craquage dans une zone de craquage. Selon ce précédé, on fait passer les particules épurées de catalyseur contaminé par du coke dans une zone de régénération par l'intermédiaire d'un circuit contenant une colonne montante de commande, le débit de circulation du catalyseur étant réglé par injection de quantités variables d'un gaz de commande dans ladite colonne montante de commande entre environ 0,07 et 0,21 kg/cm** 2 en utilisant une vanne tout en maintenant la différence de pression entre la zone de régénération et la zone de craquage à une valeur essentiellement constante. Perfectionnement au craquage catalytique.
