1. An integrated hydrotreating and hydrocracking process comprising:
contacting a hydrocarbon oil stream with a hydrogen stream and a hydrotreating catalyst in a moving-bed hydrotreating reactor to hydrotreat the hydrocarbon oil stream, thereby producing a hydrotreated hydrocarbon product stream and a spent hydrotreating catalyst;
contacting the hydrotreated hydrocarbon product stream with a second hydrogen stream and a hydrocracking catalyst in a hydrocracking reactor to crack the hydrotreated hydrocarbon oil stream, thereby producing a hydrocracked hydrocarbon product stream;
processing the spent hydrotreating catalyst to produce regenerated hydrotreating catalyst; and
recycling the regenerated hydrotreating catalyst to the moving-bed hydrotreating reactor.
