Process for producing improved carbon blacks

Patent ·
OSTI ID:5154526
This paper describes a process for producing carbon black in a reactor vessel utilizing combustion gases and feedstock oil. It comprises: supplying a linear, substantially non-swirling flow of combustion gases into a feedstock oil injection zone in the reactor, supplying at least two independently controlled streams of carbon black feedstock oil into separate segments of the flow of combustion gases in the feedstock oil injection zone wherein separate carbon black forming reactions are respectively effected in separate segments of the flow of combustion gases, and immediately thereafter supplying the combustion gas segments in which the separate carbon black forming reactions have been effected into an aggregate-forming zone whereby a carbon black product is produced which, when compounded in rubber compositions, provides the rubber compositions with improved hysteresis loss and treadwear resistance properties.
