Process for producing carbon black

Claim 1

THE METHOD OF PRODUCING A CARBON BLACK, WHICH CARBON BLACK IS HIGHLY REINFORCING WHEN COMPOUNDED WITH A GR-S TYPE SYNTHETEIC RUBBER STOCK AND THE COMPOUND VULCANIZED, COMPRISING INTRODUCING GAS OIL VAPORS FREE OF NORMALLY GASEOUS HYDROCARBONS AXIALLY INTO THE INLET END OF AN INSULATED CYLINDRICAL AND SHORT COMBUSTION ZONE HAVING AN INLET END WALL AND AN OPEN OUTLET END AND FORMING THEREIN A CENTRAL AXIAL STREAM OF GAS, INTRODUCING AIR INTO SAID COMBUSTION ZONE IN A DIRECTION TANGENT TO THE INNER WALL OF SAID COMBUSTION ZONE AND FORMING THEREBY A HELICALLY MOVING LAYER OF GAS ADJACENT SAID INNER WALL, BURNING A PORTION OF SAID GAS OIL VAPORS WITH THE TANGENTIALLY ADDED AIR TO HEAT THE REMAINING GAS OIL VAPORS TO A CARBON BLACK FORMING TEMPERATURE, PASSING SAID HELICALLY MOVING LAYER OF GAS AND CENTRAL EXIAL STREAM OF GAS CONTAINING THE COMBUSTION PRODUCTS AND THE REAMINING AIR AND HEATED GAS OIL VAPORS, WITH A PARTIAL AMOUNT OF MIXING, INTO AN ELONGAED, INSULATED AND CYLINDRICAL REACTION ZONE OF SMALLER DIAMETER OF GREATER LENGTH THAN THE COMBUSTION ZONE, THEREIN CONTINUING THE COMBUSTION OF THE GAS OIL VAPORS WITH THE REMAINDER OF THE AIR PREVIOUSLY ADDED AND CONVERTING THE MAJOR PORTIONS OF SAID REMAINING GAS OIL VAPORS TO CARBON BLACK, PASSING SAID HELICALLY MOVING LAYER OF GAS CONTAINING HOT COMBUSTION PRODUCTS FROM SAID REACTION ZONE INTO A THIRD CYLINDRICAL ZONE OF THE SAME DIAMETER AS SAID COMBUSTION ZONE AS A HELICALLY MOVING LAYER OF COMBUSTION PRODUCTS ADJACENT THE CYLINDRICAL WALL OF SAID THIRD ZONE, PASSING SAID CENTRAL AXIAL STREAM OF GAS CONTAINING THE DECOMPOSITION PRODUCTS AND SUSPENDED CARBON BLACK FROM SAID REACTION ZONE AXIALLY INTO THE THIRD ZONE AS A CORE WITHIN SAID HELICALLY MOVING LAYER OF COMBUSTION PRODUCTS, MAINTAINING IN SAID THIRD ZONE SAID CORE OF DECOMPOSITION PRODUCTS AND CARBON BLACK SUBSTANTIALLY AT THE CARBON BLACK FORMING TEMPERATURE BY RADIANT HEAT EXCHANGE CYLINDRICAL SIDEWALL AND BY DIRECT HEAT EXCHANGE FROM SAID HELICALLY MOVING LAYER OF COMBUSTION PRODUCTS, SAID THREE ZONES BEING DISPOSED ALONG A COMMON AXIS AND SUCCESSIVELY ADJACENT EACH OTHER, REMOVING THE RESULTING GASEOUS MATERIAL CONTAINING CARBON BLACK IN SUSPENSION AS AN EFFLUENT FROM SAID THIRD ZONE, COOLING SAID EFFLUENT, AND SEPARATING THE CARBON BLACK THE GASES.

Claim 2

THE METHOD OF PRODUCING A CARBON BLACK, WHICH CARBON BLACK IS HIGHLY REINFORCING WHEN COMPOUNDED WITH A GR-S TYPE SYNTHETEIC RUBBER STOCK AND THE COMPOUND VULCANIZED, COMPRISING INTRODUCING GAS OIL VAPORS FREE OF NORMALLY GASEOUS HYDROCARBONS AXIALLY INTO THE INLET END OF AN INSULATED CYLINDRICAL AND SHORT COMBUSTION ZONE HAVING AN INLET END WALL AND AN OPEN OUTLET END AND FORMING THEREIN A CENTRAL AXIAL STREAM OF GAS, INTRODUCING AIR INTO SAID COMBUSTION ZONE IN A DIRECTION TANGENT TO THE INNER WALL OF SAID COMBUSTION ZONE AND FORMING THEREBY A HELICALLY MOVING LAYER OF GAS ADJACENT SAID INNER WALL, BURNING A PORTION OF SAID GAS OIL VAPORS WITH THE TANGENTIALLY ADDED AIR TO HEAT THE REMAINING GAS OIL VAPORS TO A CARBON BLACK FORMING TEMPERATURE, PASSING SAID HELICALLY MOVING LAYER OF GAS AND CENTRAL EXIAL STREAM OF GAS CONTAINING THE COMBUSTION PRODUCTS AND THE REAMINING AIR AND HEATED GAS OIL VAPORS, WITH A PARTIAL AMOUNT OF MIXING, INTO AN ELONGAED, INSULATED AND CYLINDRICAL REACTION ZONE OF SMALLER DIAMETER OF GREATER LENGTH THAN THE COMBUSTION ZONE, THEREIN CONTINUING THE COMBUSTION OF THE GAS OIL VAPORS WITH THE REMAINDER OF THE AIR PREVIOUSLY ADDED AND CONVERTING THE MAJOR PORTIONS OF SAID REMAINING GAS OIL VAPORS TO CARBON BLACK, PASSING SAID HELICALLY MOVING LAYER OF GAS CONTAINING HOT COMBUSTION PRODUCTS FROM SAID REACTION ZONE INTO A THIRD CYLINDRICAL ZONE OF THE SAME DIAMETER AS SAID COMBUSTION ZONE AS A HELICALLY MOVING LAYER OF COMBUSTION PRODUCTS ADJACENT THE CYLINDRICAL WALL OF SAID THIRD ZONE, PASSING SAID CENTRAL AXIAL STREAM OF GAS CONTAINING THE DECOMPOSITION PRODUCTS AND SUSPENDED CARBON BLACK FROM SAID REACTION ZONE AXIALLY INTO THE THIRD ZONE AS A CORE WITHIN SAID HELICALLY MOVING LAYER OF COMBUSTION PRODUCTS, MAINTAINING IN SAID THIRD ZONE SAID CORE OF DECOMPOSITION PRODUCTS AND CARBON BLACK SUBSTANTIALLY AT THE CARBON BLACK FORMING TEMPERATURE BY RADIANT HEAT EXCHANGE CYLINDRICAL SIDEWALL AND BY DIRECT HEAT EXCHANGE FROM SAID HELICALLY MOVING LAYER OF COMBUSTION PRODUCTS, SAID THREE ZONES BEING DISPOSED ALONG A COMMON AXIS AND SUCCESSIVELY ADJACENT EACH OTHER, REMOVING THE RESULTING GASEOUS MATERIAL CONTAINING CARBON BLACK IN SUSPENSION AS AN EFFLUENT FROM SAID THIRD ZONE, COOLING SAID EFFLUENT, AND SEPARATING THE CARBON BLACK THE GASES.
