Carbon black process

Claim 1

THE PROCESS OF PRODUCING A FINELY DIVIDED CARBONACEOUS PRODUCT COMPRISING CONTINUOUSLY INTRODUCING A MIXTURE OF A GAS OIL AND A COMBUSTIBLE COMPOUND OF AN ELEMENT SELECTED FROM THE GROUP OF ELEMENTS CONSISTING OF SILICON, BORON AND GERMANIUM, IN A VAPOAROUS STATE INTO THE INLET END AND AT A MIDPOINT OF A SHORT CYLINDRICAL COMBUSTION ZONE HAVING AN INLET END WALL AND AN OUTLET END WALL, SAID OUTLET END WALL HAVING A CIRCULAR OPENING CONCENTRIC WITH RESPECT TO THE PERIPHERY OF THE ZONE, INTRODUCING INTO THE COMBUSTION ZONE THROUGH A BURNER PORT A COMBUSTIBLE MIXTURE CONTAINING AN EXCESS OF FREE OXYGEN AND BURNING THE SAME TO HEAT THE VAPOROUS GAS OIL AND COMBUSTIBLE COMPOUND OF SAID ELEMENT BY DIRECT HEAT EXCHANGE, SAID BURNER PORT BEING POSITIONED TO DIRECT THE FLOW OF SAID COMBUSTIBLE MIXTURE AND EXCESS OXYGEN IN A DIRECTION TANGENT TO THE INNER SURFACE OF THE CYLINDRICAL SIDE WALL AND PERPENDICULAR TO THE LONGITUDINAL AXIS OF SAID ZONE TO GIVE A SPIRALLY INWARD MOTION TO THE FLAME AND COMBUSTION PRODUCT; MOVING THE HEATED GAS OIL AND COMBUSTIBLE COMPOUND OF SAID ELEMENT INTO THE INLET END OF AN UNOBSTRUCTED ELONGATED CYLINDRICAL ZONE HAVING A DIAMETER SMALLER THAN THE DIAMETER OF THE FIRST MENTIONED ZONE, THE INLET END OF SAID ELONGATED ZONE FORMING THE OPENING IN THE OUTLET END WALL OF SAID FIRST MENTIONED ZONE AND SAID ZONES HAVING A COMMON LONGITUDINAL AXIS, THE SPIRAL MOTION IMPARTED TO THE COMBUSTION PRODUCTS IN THE COMBUSTION ZONE ACTING TO MOVE SAID HOT COMBUSTION PRODUCTS AND FREE OXYGEN HELICALLY AND AS A HOLLOW ROTATING CYLINDER SURROUNDING SAID HEATED GAS OIL AND COMBUTIBLE COMPOUND OF SAID ELEMENT AS A CORE THROUGH THE SECOND ZONE, SAID HELICALLY MOVING HOT COMBUSTION PRODUCTS AND OXYGEN MOVING THROUGH SAID SECOND ZONE HEATING FURTHER THE HOT GAS OIL AND COMBUSTIBLE COMPOUND OF SAID ELEMENT AND CONVERTING CARBON THEREFROM TO ELEMENTARY CARBON AND SAID COMBUSTIBLE COMPOUND OF SAID ELEMENT TO AN OXIDE OF SAID ELEMENT; COOLING THE EFFLUENTS OF THE SECOND AND ELONGATED ZONE TO A TEMPERATURE BELOW THAT AT WHICH SAID ELEMENTARY CARBON IS REACTIVE, AND SEPARATING THE CARBONACEOUS PRODUCT FROM THE SUSPENDING GASES AND REMOVING SAME AS THE FINELY DIVIDED CARBONACEOUS PRODUCT OF THE PROCESS.
