Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
115 words
A process for the conversion of solid-containing liquid hydrocarbon oils, said solids containing in excess of about 50 weight per cent of inorganic components, which comprises introducing said solid-containing liquid hydrocarbon oils and hydrogen into a reaction vessel comprising a plurality of reaction zones separated by porous partitions, a portion of said zones containing a solid particulate hydrogenation catalyst which will not pass through said porous partitions and the remainder of said zones forming substantially unobstructed passageways through said reaction vessel and passing said liquid hydrocarbon oils and hydrogen through said unobstructed passageways and through said porous partitions into contact with said catalyst under hydrogenation conditions, whereby hydrogenation of said liquid hydrocarbon oils takes place.
Claim 2
Dependent Claim
