Abstract
Abstract Process and apparatus for the production of carbon black by the pyrolytic decomposition of a hydrocarbon feed wherein the hydrocarbon feed is dispersed by impingement on a screen spaced apart from the feed nozzle in an oxygen-containing gas and the resulting mixture commingled with hot combustion gases whereby the hydrocarbon feed is pyrolytically decomposed to carbon black. Vaporous fuel is preferably introduced into admixture with the oxygen-containing gas.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
45 words
The process as defined in claim 1 in which said first free oxygen-containing gas is air and is introduced into said reactor in an amount within the range of from about 10 to about 70 volume percent of the total air introduced into the process.
Claim 2
Dependent Claim
16 words
The process of claim 2 in which vaporous fuel is introduced in admixture with said air.
Claim 3
Dependent Claim
19 words
The process of claim 3 in which said hydrocarbon feed is introduced as a spray having a cone-shaped configuration.
Claim 4
Dependent Claim
24 words
The process of claim 3 in which said hydrocarbon feed is introduced into said reactor downstream of the locus of introduction of said air.
Claim 5
Dependent Claim
43 words
The process as defined in claim 4 in which said air and said fuel are introduced longitudinally into said reactor with said hydrocarbon feed spray as a plurality of streams, said air and said fuel being introduced peripherally to said hydrocarbon feed spray.
