Manufacture of carbon black

Claim 1

IN THE PROCESS OF PRODUCING FURNACE BLACK BY THE THERMAL DECOMPOSITION OF HYDROCARBONS WHEREIN THE HYDROCARBON IS RAPIDLY AND UNIFORMLY MIXED WITH HOT BLAST FLAME GASES PASSING THROUGH A CONFINED, ELONGATED REACTION CHAMBER AND DECOMPOSED BY HEAT ABSORBED FROM THE HOT GASES TO FORM CARBON BLACK IN SUSPENSION, THE SUSPENSION BEING WITHDRAWN FROM THE DOWNSTREAN END OF THE REACTION CHAMBER AND THE CARBON BLACK SEPARATED THEREFROM, THE STEPS COMPRISING GENERATING A PLURALITY OF STREAMS OF HOT BLAST FLAME GASES AND SEPARATELY PASSING THE RESPECTIVE STREAMS AT HIGH VELOCITY INTO ONE END OF AN ELONGATED REACTION CHAMBER OF SUBSTANTIALLY CYLINDRICAL CROSS-SECTION IN A DIRECTION SUBSTANTIALLY AT RIGHT ANGLES TO THE LONGITUDINAL AXIS OF THE CHAMBER, AND GENERALLY TANGENTIAL THERETO, SEPARATELY INJECTING A STREAM OF THE HYDROCARBONS TO BE DECOMPOSED INTO EACH OF THE RESPECTIVE STREAMS OF BLAST FLAME GASES, JUST AS IT ENTERS THE REACTION CHAMBER, IN A DIRECTION SUBSTANTIALLY AT RIGHT ANGLES TO THE DIRECTION OF FLOW OF THE HOT GAS STREAM, AND IMMEDIATELY THEREAFTER, IMPINGING EACH OF THE RESULTANT STREAMS OF BLAST FLAME GASES AND HYDROCARBONS AT A SUBSTANTIAL ANGLE UPON AN ENTERING ADJACENT STREAM OF BLAST FLAME GASES AND HYDROCARBON AND THEREBY RAPIDLY UNIFORMLY MIXING THE HYDROCARBONS WITH THE HOT GASES.
