Abstract
Heavy petroliferous stocks such as vacuum and atmospheric resids, tar sand oils, shale oils, liquids from conversion of coal and the like are concurrently distilled and hydroprocessed for removal of sulfur, nitrogen and metals and are hydrocracked or otherwise hydroprocessed in a packed distillation column under hydrogen pressure wherein the packing is constituted, at least to a substantial extent in both stripping and rectifying sections by catalyst suited to the desired conversions.
