This patent describes a hydrotreating process, comprising the steps of: feeding a hydrotreating catalyst into an ebullated bed reactor; partially filling the ebullated bed reactor to a level defining a liquid level below the top of the reactor with a feed comprising oil and hydrogen-rich gases; raising the level of the feed by activating an ebullating pump and concurrently ebullating, contacting, and mixing the feed with the catalysts; floating a tubular pan upon the feed partially below the level in the reactor and at least partially above a downcomer to allow the pan to rise in response to the rising of the liquid level for facilitating flow of the feed to the downcomer; directing the feed substantially downwardly through the pan and the downcomer in the ebullated bed reactor; and mixing and contacting the oil and the hydrogen-rich gases with the catalyst to produce hydrotreated oil.
