ABSTRACT:
A hydrocracking process wherein a hydrocarbonaceous feedstock and hydrogen is passed to a denitrification and desulfurization reaction zone and then directly to a hot, high pressure stripper utilizing a hot, hydrogen-rich stripping gas to produce a liquid hydrocarbonaceous stream which is passed to a hydrocracking zone. The resulting effluent from the hydrocracking zone is then directly passed to the hot, high pressure stripper. A vapor stream from the hot, high pressure stripper is passed to a post-treat hydrogenation reaction zone to saturate at least a portion of the aromatic compounds contained therein.
