A hydrotreating process is described for an ebullated bed reactor, comprising the steps of: feeding an oil feed comprising resid into a common feed line; injecting a gas feed comprising hydrogen-rich gases into the feed line; dispersing the gas feed in the oil feed line; passing the gas and oil feeds from the feed line into a single feed distributor comprising an annular manifold in the bottom portion of an ebullated bed reactor; annularly distributing and discharging the oil and gas feeds from the same single feed distributor in the bottom portion of the reactor in a generally uniform flow pattern, some of the oil and gas feeds being discharged substantially downwardly from the single feed distributor; passing the oil and gas feeds generally upwardly through a set of bubble caps; conveying a hydrotreating catalyst to the reactor; ebullating and hydroprocessing the oil and gas feeds in the presence of the hydrotreating catalyst in the ebullated bed reactor to produce an upgraded hydrotreated oil; and withdrawing the upgraded hydrotreated oil from the reactor.
