Hydroconversion of solid carbonaceous materials

Claim 1

A PROCESS FOR THE HYDROCONVERSION OF A SOLID CARBONACEOUS MATERIAL WHICH COMPRISES FORMING A SLURRY OF SAID SOLID CARBONACEOUS MATERIAL WITH A HYDROCARBON LIQUID BOILING IN THE MIDDLE DISTILLATE RANGE, PASSING SAID SLURRY AS A CONFINED STREAM THROUGH A HYDROGENATION ZONE MAINTAINED AT A TEMPERATURE BETWEEN ABOUT 700 AND 1500*F., A PRESSURE BETWEEN ABOUT 1500 AND 10,000 P.S.I.G. AND A TURBULENCE LEVEL OF BETWEEN ABOUT 50 AND 1000 IN THE PRESENCE OF HYDROGEN, SEPARATING THE EFFLUENT FROM SAID HYDROGENATION ZONE INTO A GAS CNTAINING HYDROGEN, A FRACTION CONTAINING HYDROCARBON GASES, A FRACTION BOILING IN THE MOTOR FUEL RANGE, A FRACTION BOILING IN THE MIDDLE DISTILLATE RANGE AND A HEAVY OIL, RECYCLING SAID GAS CONTAINING HYDROGEN TO THE HYDROGENATION ZONE, RECYCLING AT LEAST A PORTION OF SAID RRACTION BOILING IN THE MIDDLE DISTILLATE RANGE TO FORM ADDITIONAL SLURRY, FORMING A SECOND SLURRY OF FINELY-DIVIDED SOLID CARBONACEOUS MATERIAL WITH AT LEAST A PORTION OF SAID HEAVY OIL, SUBJECTING SAID SECOND SLURRY TO PARTIAL COMBUSTION TO PRODUCE A GAS CONTAINING HYDROGEN AND CARBON MONOXIDE, BLENDING A PORTION OF SAID GAS CONTAINING HYDROGEN AND CARBON MONOXIDE WITH SAID FRACTION CONTAINING HYDROCARBON GASES TO PRODUCE A GAS SUITABLE FOR USE AS A HEATING GAS, SUBJECTING THE BALANCE OF SAID GAS CONTAINING HYDROGEN AND CARBON MONOXIDE TO A WATER GAS SHIEFT REACTION TO PRODUCE A HYDROGEN RICH GAS AND INTRODUCING SAID HYDROGEN RICH GAS INTO THE HYDROGENATION ZONE AS MAKE-UP HYDROGEN.
