ABSTRACT:
A method and apparatus for producing carbon black in which combustion gas is introduced into a precombustion or combustion zone of a carbon black reactor in a manner to produce a vortex of combustion gases traveling axially through said reactor and a flow of fluid which contains feedstock is introduced into the reactor in a manner to produce another axially moving vortex internal to the combustion gas vortex with both of these vortices passed through a combustion zone to produce carbon black. In embodiments of the invention, method and apparatus for producing a vortex of feedstock, a vortex of cooling air interfaced with axially flowing feedstock, or combined vortices of feedstock and cooling air. In embodiments of the invention, feedstock and/or cooling air are given the same rotational flow as that of the combustion gases to produce carbon black of decreased structure or the feedstock and/or coolig air are given counter-rotational flow to that of the combustion gases to reduce ash deposit in the carbon black reactor.
