Abstract

Une charge lourde, telle que du gasoil ou du gasoil sous vide, est ajoutée au réacteur à colonne montante (6) par l'intermédiaire d'ajutages (2) d'injection de charge. La réaction de craquage est presque réalisée dans le réacteur à colonne montante, lequel tourne à 90 degrés au sommet du réacteur au niveau d'un coude (10). Le catalyseur usé et les produits de craquage déchargés depuis le réacteur à colonne montante passent à travers le cyclone (12) de la collone montante, lequel sépare efficacement la majeure partie du catalyseur usé et le produit de craquage. Ce dernier est déchargé dans un dispositif de débrayage (14) et éventuellement éliminé par l'intermédiaire de cyclones supérieurs (16) et du conduit (18) vers la colonne de fractionnement.
