Abstract
A multiple bed downflow hydrocarbon hydroprocessing reactor is modified by the addition of a phase separator above at least one of the catalyst beds. This enables the lighter fraction of the hydrocarbon, which has passed through the upper bed(s) in the vapor phase and thus not been heavily hydroprocessed, to be hydroprocessed in the absence of the liquid heavier fraction in the same reactor.
