Catalytic hydrogenation of blended coal and residual oil feeds

摘要

A process is provided for the simultaneous conversion of coal and residuum oil to predominantly liquid products, employing ebullated bed techniques. A fluid blend of particulate coal admixed with crude oil comprising from about 20 to 100% by weight of residuum oil boiling above about 975 DEG F. is contacted with hydrogen in the presence of an ebullated bed of particulate hydrogenation catalyst to effect conversion of at least about 50% of the residuum oil component and up to about 94% of the m.a.f. coal. In an alternate embodiment the oil feed includes recycled oil from the product liquids.
