Abstract
A process is provided for the conversion of solid-containing liquid hydrocarbon oils, and in particular for the hydrogenation of solid-containing liquid hydrocarbon oils derived from coal, oil shale and tar sands. The process comprises passing a solid-containing liquid hydrocarbon oil, together with hydrogen, through a reaction vessel that contains a plurality of reaction zones separated by porous partitions. A portion of said zones is adapted to contain a solid particulate hydrogenation catalyst which will not pass through said porous partitions. The remainder of said zones form substantially unobstructed passageways through said reaction vessel. The volumetric ratio of catalyst zones to substantially unobstructed passageways is about 10:1 to about 1:10.
