Beschreibung
Zusammenfassung:	A hydroprocessing process including a cocurrent flow liq-uid reaction stage, a countercurrent flow liquid reaction stage and a vapor reaction stage in which feed components are catalytically hydroprocessed by reacting with hydrogen is disclosed. A hydro-carbon feed (50) and hydrogen (54) are passed via line (52) to a cocurrent reaction stage in vessel (12) in order to produce a mixed liquid and vapor effluent (56). The mixed liquid and vapor effluent (56) is separated in flash zone (22) in vessel (16). The liquid ef-fluent is subjected to a countercurrent reaction stage with hydrogen (58) in vessel (16) in order to produce a liquid effluent (60). Next, the liquid stage effluents are combined and catalytically reacted in bed (20) with hydrogen to form a hydroprocessed vapor (62).
