PROCESS AND APPARATUS FOR PRODUCING IMPROVED CARBON BLACKS AND RESULTANT PRODUCT

A new process and apparatus for producing carbon black is provided. Carbon black feedstock oil is fed in multiple and separately-controlled streams through nozzles (17) to an input zone (2) of the reactor which is difided into frusto-conical (23) and cylindrical (24) portions. The difference in dwel...

Zusammenfassung:	A new process and apparatus for producing carbon black is provided. Carbon black feedstock oil is fed in multiple and separately-controlled streams through nozzles (17) to an input zone (2) of the reactor which is difided into frusto-conical (23) and cylindrical (24) portions. The difference in dwell time of the streams is at least half of one millisecond. The process utilizes such a reactor to give unique carbon blacks which give rise to low hysteresis loss and good wear when used in rubber compounds for reinforcement and particularly in rubber tyres.
