CATALYTIC HYDROGENATION REACTOR

摘要

This invention relates to a catalytic hydrogenation reactor suitable for hydrogenating oil in an ebullated bed of catalyst particles, said reactor being a vertical cylindrical closed shell having an inlet for liquids at the lower end and an outlet for vapors at the upper end, and having internally disposed inside the upper end of the shell a truncated conical collector joined to the inside wall of the shell and connected at its upper end to a short cylindrical weir; the weir, which has an internal crosssectional area approximately one-half of the internal crosssectional area of the shell, serving to remove liquid product from the ebullating bed Also included in the reactor is a downcomer conduit located near the wall of the shell and joining the collector at one end means such as a pump for recirculating liquid; packing means internally disposed in the lower end of the shell for diverting and distributing liquid feed material introduced through the inlet of the shell; and means for introducing fresh catalyst into and removing spent catalyst from, the interior of said shell.
