Abstract
The invention is an improvement in an ebullated bed process. Gas is removed from the vertically oriented reaction vessel until the vessel, including the recycle conduit is liquid filled. Foam, generated around the recycle cup and riser conduits is floated to the top of the reaction vessel by liquid and is prevented from entering the recycle conduit. A more stable hydrodynamic system is thereby achieved.
