Claim 14:
15. A system for hydrotreating and hydrocracking a hydrocarbon oil stream, the system comprising:
a moving-bed hydrotreating reactor configured to hydrotreat the hydrocarbon oil stream and a hydrogen stream with a hydrotreating catalyst to hydrotreat the hydrocarbon oil stream and form a hydrotreated hydrocarbon product stream and spent hydrotreating catalyst;
a hydrocracking reactor fluidly connected to the moving-bed hydrotreating reactor and configured to crack the hydrotreated hydrocarbon product stream and a second hydrogen stream to form a hydrocracked hydrocarbon product stream;
a stripper fluidly connected to the moving-bed hydrotreating reactor and configured to strip the spent hydrotreating catalyst to form a stripped hydrotreating catalyst; and
a catalyst regenerator fluidly connected to the stripper and the moving-bed hydrotreating reactor and configured to regenerate the stripped hydrotreating catalyst to form a regenerated hydrotreating catalyst.
