Zusammenfassung:This invention relates to a two stage hydroprocessing process with interstage stripping. More particularly, the interstage stripping occurs at high pressure and temperature with recycle of high temperature gaseous effluent from the stripping stage. This invention relates to a two stage hydroprocessing process with stripping zones between the hydroprocessing zones and following the last hydroprocessing zone. The stripping occurs at high pressure and temperature with no disengagement between or following the hydroprocessing zones. There is recycle of high temperature gaseous effluent from the last stripping zone to the first stripping zone.
