Claim:
1. A hydrogenation reactor system, comprising: a magnetic conditioning zone to pass a liquid hydrocarbon feedstream through a magnetic field to separate magnetically susceptible particles from the hydrocarbon and form a magnetically lean stream; an inlet flow path to introduce the magnetically lean stream from the magnetic conditioning zone into a fixed catalyst bed; an outlet flow path from an outlet end of the catalyst bed to withdraw reactor effluent; and a bypass tube assembly comprising a plurality of tubes, at least a portion of the tubes comprising: an inlet opening at or above an inlet surface of a foulant accumulation zone of the fixed catalyst bed to receive the magnetically lean stream, and a plurality of openings through a wall of at least one tube to distribute the magnetically lean stream into the fixed catalyst bed below the inlet surface.
