Zusammenfassung:	Methods and apparatuses are disclosed for upgrading a hydrocarbon feedstream comprising passing the hydrocarbon feedstream to a first hydroprocessing reactor in a reaction vessel to produce a first hydroprocessed effluent stream. The first hydroprocessed effluent stream is separated in a hot separator to produce a vapor stream and a liquid hydrocarbon stream. At least a portion of the liquid hydrocarbon stream is passed to a second hydroprocessing reactor disposed in the reaction vessel above the first hydroprocessing reactor, to produce a second hydroprocessed effluent stream. A liquid product stream is separated from the second hydroprocessing effluent stream. The vapor stream from the hot separator is mixed with the liquid product stream to provide a combined stream.
