ABSTRACT:
A process is provided for the conversion (including upgrading) of solid carbonaceous materials, and in particular for the hydrogenation of coal slurries. The process comprises passing a slurry composed of solid carbonaceous material and solvent, 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 forms substantially unobstructed passageways through said reaction vessel. The volumetric proportion of substantially unobstructed passageways to catalyst zones is preferably from about 20:1 to about 1:10.
