PROCESS FOR PRODUCING CARBON BLACKS AND NEW CARBON BLACKS

摘要

A process for producing carbon blacks comprised of mixing an oxidant, primary fuel, and carbon black feedstock to form carbon black particles and aggregates, passing the mixture through a reactor, cooling, separating, and recovering the carbon black product. The improvement comprises the addition of a secondary oxidant-containing stream to the reactor such that the secondary oxidant stream does not interfere with the formation of the carbon black particles and aggregates in the reactor. Also disclosed are new carbon black products defined by the following parameters: 35 mg/g
