Production of carbon black

Claim 1

A PROCESS FOR PRODUCING CARBON BLACK HAVING HIGH REINFORCING PROPERTIES IN RUBBER SIMILAR TO THOSE OF CHANNEL BLACK WHICH COMPRISES ESTABLISHING IN A GENERALLY CYLINDRICAL FIRST ZONE HAVING A DIAMETER GREATER THAN ITS LENGTH A ROTATING MASS OF HOT COMBUSTION GASES BY INJECTING THEREINTO PREVIOUSLY PRODUCED HOT COMBUSTION GASES, CONTINUOUSLY INJECTING ADDITIONAL HOT COMBUSTION GASES TO SAID ROTATING MASS TO MAINTAIN A TEMPERATURE ABOVE APPROXIMATELY 2600* F. IN SAID FIRST CYLINDRICAL ZONE, CONTINUOUSLY PASSING A PORTION OF SAID GASES WHILE SO ROTATING INTO A GENERALLY CYLINDRICAL SECOND ZONE THE LENGTH OF WHICH IS GREATER THAN ITS DIAMETER AND THE DIAMETER OF WHICH IS LESS THAN THAT OF SAID FIRST ZONE, SAID SECOND ZONE BEING IN COMMUNICATION WITH AND IN AXIAL ALIGNMENT WITH SAID FIRST ZONE WHEREBY A HELICAL MOVEMENT OF SAID GASES IS PROVIDED ALONG THE INNER SURFACE OF SAID SECOND ZONE, INTRODUCING A VAPOROUS HYDROCARBON ALONG THE AXIS OF SAID FIRST ZONE AND PASSING IT AXIALLY THROUGH SAID ROTATING MASS IN SAID FIRST ZONE AND AXIALLY INTO THE CENTER OF SAID HELICALLY MOVING GASES IN SAID SECOND ZONE, FORMING CARBON BLACK FROM SAID VAPOROUS HYDROCARBON BY PYROCHEMICAL ACTION DUE TO THE HEAT OF THE SURROUNDING HOT COMBUSTION GASES WITHOUT THE FURTHER ADDITION OF ANY SUBSTANTIAL AMOUNT OF AIR, AND SEPARATING SAID CARBON BLACK FROM THE RESULTANT GASEOUS PRODUCTS OF SAID PROCESS.
