ABSTRACT A process for producing carbon black by a reaction conducted in a first reaction zone in which by a high temperature combustion gas-generating system, an oxygen- containing gas and a fuel are mixed and burned to form a high temperature combustion gas stream, a second reaction zone having a throat in which a hydrocarbon feedstock is mixed to the high temperature combustion gas stream thus obtained, to form carbon black and a third reaction zone located down stream and continuous from the second reaction zone, in which quenching water is sprayed to terminate the reaction, which comprises: (i) introducing into the first reaction zone said high temperature combustion gas stream in the from of two types of high temperature combustion gas streams i.e. a stream in the direction of the reactor axis (axial stream) and a stream in the tangential direction (tangential stream), and letting the two gas stream meet each other to form a composite stream of the high temperature combustion gas; and (ii) in the second reaction zone, introducing the hydrocarbon feedstock to the composite stream of the high temperature combustion gas for reaction.
