Balanced hydrogenation of coal

Claim 1

A PROCESS FOR THE PRODUCTION OF MOTOR FUEL OF HIGH AROMATIC CONTENT SUBSTANTIALLY FREE OF ASPHATIC FRACTION BY THE DIRECT HYDROGENATION OF COAL IN A SINGLE STAGE WHICH COMPRISES THE STEPS OF PULVERIZING THE COAL, IMPREGNATING THE PULVERIZED COAL WITH A HYDROGENATION CATALYST SELECTED FROM THE GROUP CONSISTING OF AMMONIUM MOLYBDATE, NICKELOUS CHLORIDE, AND STANNOUS CHLORIDE, MIXING THE IMPREGNATED COAL WITH AN ASPHALT-FREE DISTILLATE FRACTION OF OIL FROM THE HYDROGENATION OF COAL, TO FORM A COAL-OIL PASTE, SUBJECTING SAID PASTE TO CONVERSION IN THE PRESENCE OF HYDORGEN FOR A PERIOD OF TIME OF ABOUT 15 SECONDS TO 15 MINUTES AT A TEMPERATURE OF NOT LESS THAN 500*C. AND UNDER A PERSSURE NOT LESS THAN 475 ATMOSPHERES, PASSING THE EFFLUENT FROM SAID CONVERSION THROUGH A COOLING ZONE TO SEPARATING OUT A NON-ASPHATIC LIQUID FRACTION ADMIXED WITH SOLID RESIDUES AND AN OVERHEAD FRACTION COMPRISING NON-CONDENSABLE HYROCARBON GASES, INTRODUCING SAID NON-CONDENSABLE HYDROCARBON GASES INTO A REFORMING ZONE, REACTING THE SAID GASES WITH STEAM AND OXYGEN TO PRODUCE HYDROGEN, CONSUCTING THE HYDROGEN TO THE CONVERSION STEP OF THE PROCESS, DISTILLING FROM SAID LIQUID FRACTION AN SROMATIC GASELINE BOILING BELOW 200*C., SEPARATING FROM THE RESIDENTIAL OIL THE SOLID RESIDUES AND RECYCLING THE MAJOR PORTION OF SAID RESIDUAL OIL FOR ADMIXTURE WITH FRESH IMPREGNATED COAL SUPPLIED TO THE PROCESS.
