Abstract
Abstract An apparatus for producing carbon black in which a first reactant mass is formed and thoroughly mixed and passed axially through the reactor, a second mass of hot combustion gases being passed helically to the axially flowing mass.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A carbon reactor comprising: a. a first section with conduit means for the introduction of a plurality of reactants thereinto, said conduit means restricted to axial and radial flow with means to introduce at least one reactant with axial flow and means to introduce at least one reactant with radial flow; b. a means in open communication with said first section for producing a mixed reactant mass in axial, non-rotating flow; c. a second section in open communication with said means for producing said reactant mass, said second section having along its length a plurality of means spaced tangentially to said second section for introducing combustion gases; d. a pyrolytic carbon black forming section in open communication with said second section; and e. conduit means for the recovery of carbon black from said carbon black forming section.
Claim 2
Dependent Claim
137 words
A carbon reactor comprising: a. a first section with conduit means for the introduction of a plurality of reactants thereinto, said conduit means restricted to axial and radial flow with means to introduce at least one reactant with axial flow and means to introduce at least one reactant with radial flow; b. a means in open communication with said first section for producing a mixed reactant mass in axial, non-rotating flow; c. a second section in open communication with said means for producing said reactant mass, said second section having along its length a plurality of means spaced tangentially to said second section for introducing combustion gases; d. a pyrolytic carbon black forming section in open communication with said second section; and e. conduit means for the recovery of carbon black from said carbon black forming section.
Claim 3
Dependent Claim
17 words
A reactor of claim 1 wherein said means for producing of said reactant mass is a venturi.
Claim 4
Dependent Claim
34 words
A reactor of claim 1 in which said conduit means for the introduction of reactants into said first section comprises a plurality of conduits apertured to discharge along the length of said first section.
Claim 5
Dependent Claim
52 words
The reactor of claim 2 in which the walls of the upstream section of said venturi converge at a total angle of from about 5° to about 10° and in which the walls of the downstream section of said venturi diverge at a total angle of from about 10° to about 25°.
Claim 6
Dependent Claim
32 words
The reactor of claim 1 in which said section comprises at least one conduit for the introduction of hot combustion gases substantially parallel to the direction of axial flow through said reactor.
Claim 7
Dependent Claim
33 words
The reactor of claim 3 in which said second section comprises at least one conduit for the introduction of hot combustion gases substantially parallel to the direction of axial flow through said reactor.
Claim 8
Dependent Claim
23 words
The reactor of claim 1 in which said carbon black forming section has a diameter less than the diameter of said second section.
