Internal components for a vertical downflow reactor include a closed-ended conduit having an internal baffle and longitudinal exit slots proximate its closed end for the symmetrical introduction of quench fluid into a quench zone. An interzone mixing configuration is in vertical communication with the bottom of the quench zone. An inwardly sloping collector tray has an opening concentric with the vertical axis of the reactor vessel. A mixing device is provided for mixing the liquid and vapor components entering from above the collector tray and conveying the mixed vapor and liquid downwardly through the opening. Flow deflectors are positioned immediately below the collector tray opening for directing liquid flow towards the axial centerline of the reactor. The flow deflectors take the form of four pie-shaped plates which are configured to collectively occupy between 25 to 75 percent of the concentric circular opening the collector tray and may slope downwardly at an angle of from about 30.degree. to about 60.degree. from the horizontal. A collection pan is positioned below and in axial alignment with the collector tray to capture and retain the liquid. A radially outwardly flared downwardly extending skirt is provided to disperse the liquid flowing from the collector pan toward the reactor walls. A continuous vertical spiral weir is provided on the surface of the collector tray to add residence time to the liquid on the tray for mixing of the liquid thereon.
