Abstract

La présente invention a pour objet un procédé associé de catalyse fluide. Elle est caractérisée en ce que l'on dirige la suspension radialement par des branches disposées dans la périphérie extérieure de la zone ascendante et en dessous des passages de récupération du catalyseur en formant un courant de catalyseur substantiellement étranglé, en général séparé des vapeurs hydrocarbonées produites et en ce que l'on recourbe lesdites branches de récupération du catalyseur, à proximité de leurs extrémités, de façon à produire dans ledit courant de catalyseur étranglé une force centrifuge Elle se rapporte à un procédé amélioré de conversion de charges hydrocarbonées.The present invention relates to an associated process for fluid catalysis. It is characterized in that the suspension is directed radially by branches arranged in the outer periphery of the ascending zone and below the catalyst recovery passages, forming a substantially constricted stream of catalyst, generally separated from the hydrocarbon vapors produced. and in that said catalyst recovery branches are bent near their ends so as to produce centrifugal force in said throttled catalyst stream. It relates to an improved process for converting hydrocarbon feedstocks.
