A catalytic hydrocracking process wherein a hydrocarbonaceous feedstock and a liquid recycle stream is contacted with hydrogen in a hydrocracking reaction zone at elevated temperature and pressure to obtain conversion to lower boiling hydrocarbons. The process utilizes a hydrogenation zone located in the lower end of a hot, high pressure stripper to hydrogenate downwardly flowing liquid hydrocarbons in contact with upwardly flowing hydrogen.

La présente invention concerne un processus d'hydrocraquage catalytique dans lequel une charge hydrocarbonée et un flux de recyclage liquide sont mis en contact avec de l'hydrogène dans une zone de réaction d'hydrocraquage à température et à pression élevés, de façon à obtenir une conversion en hydrocarbures à ébullition plus basse. Ce processus utilise une zone d'hydrogénation située au niveau de l'extrémité inférieure d'une colonne de stripping chaude et sous haute pression de façon à hydrogéner les hydrocarbures liquides s'écoulant vers le bas en contact avec l'hydrogène s'écoulant vers le haut.
