Abstract

Carbon black is produced in a flow reaction by spraying a hydrocarbon containing liquid feedstock with the aid of a propellant gas into a stream of hot reaction gases produced by burning a fuel, the feedstock-propellant gas-jet enters the reaction zone with a spraying angle that is greater than the spreading angle of a free jet. There is also described an apparatus for carrying out the process which comprises a binary injector supporting an atomizing nozzle whose head has several channels which are adjusted from zero degrees to different angles to the longitudinal axis of the nozzle.
