Claims
- 1. A process for producing carbon black comprising:
- a. introducing reactant materials comprising hydrocarbon feed and fuel gas axially into a first section of a carbon black reactor with an oxidant introduced in radial flow to produce a first reactant mass;
- b. passing said reactants through a mixing zone producing a nonrotating first reactant mass flowing longitudinally in the reactor;
- c. passing the non-rotating reactant mass into a second section of the carbon black reactor with addition of a tangential flow of air and an axial flow of fuel gas to produce a total reaction mass comprising a non-rotating reactant mass flowing longitudinally in the reactor surrounded by a helically flowing mass of hot combustion gases;
- d. passing the total reactant mass into a pyrolytic reaction section to produce carbon black; and
- e. recovering the carbon black produced.
- 2. The process of claim 1 wherein from about 40 percent to about 60 percent by volume of the total combustion gases is supplied to the first section of the carbon black reactor.
- 3. The process of claim 1 wherein the first reactant mass is passed through a mixing zone comprising a venturi producing a non-rotating reactant mass thereby.
