Independent Claim
163 words
A PROCESS FOR THE PRODUCTION OF A HEATING GAS WHICH COMPRISES PASSING A LIQUID HYDROCARBON CONTAINING ASHFORMING IMPURITIES THROUGH A TUBULAR HYDROGENATION ZONE WITH HYDROGEN AT A PRESSURE BETWEEN ABOUT 3000 AND 10,000 P.S.I.G. AND A TEMPERATURE BETWEEN ABOUT 950 TO 1100*F. UNDER CONDITIONS OF TURBULENT FLOW AT A TURBULENCE LEVEL OF AT LEAST 25 TO CONVERT A PORTION THEREOF TO A GAS OF HIGH HEATING VALUE, SEPARATING THE REACTION PRODUCT INTO A LIQUID PORTION AND A GASEOUS PORTION SUBJECTING AT LEAST A PORTION OF THE SEPARATED LIQUID PORTION TO PARTIAL COMBUSTION WITH A FREE OXYGEN-CONTAINING GAS TO PRODUCE A GAS CONTAINING HYDROGEN THE AMOUNT OF FREE OXYGEN BEING SUFFICIENT TO CONVERT NOT LESS THAN ABOUT 90% AND NOT MORE THAN 99.5% OF THE CARBON CONTENT OF THE LIQUID PORTION TO CARBON OXIDES THE WEIGHT OF SOLID UNCONVERTED CARBON BEING AT LEAST 50 TIMES THE COMBINED WEIGHT OF THE METALS CONTAINED IN SAID LIQUID PORTION, RECOVERING THE UNCONVERTED CARBON TOGETHER WITH ANY SE-
