(57) Abstract: A catalytic hydrocracking process wherein a first hydrocarbonaceous feedstock is contacted with
hydrogen and a metal promoted hydrocracking catalyst in a hydrocracking reaction zone at elevated temperature and
pressure to obtain conversion to lower boiling hydrocarbons. The resulting hot, uncooled effluent from the
hydrocracking reaction zone is hot hydrogen stripped in a stripping zone maintained at essentially the same pressure
as the hydrocracking zone to produce a first gaseous hydrocarbonaceous stream and a first liquid hydrocarbonaceous
stream is preferably recycled to the hydrocaracking reaction zone. A second hydrocarbonaceous feedstock having a
boiling temperature range lower than that of the first hydrocarbonaceous feedstock is introduced into an upper end of
the stripper to serve as reflux. The first gaseous hydrocarbonaceous stream is removed from the stripper and passed to
a post-treat hydrogenation reaction zone to saturate aromatic compounds.
