method is the more widely used process for producing carbon black. In this process, heavy aromatic oils are introduced by a hot gas stream into a pyrolyzation furnace to form microscopic carbon particles. The particles may be further processed to remove any impurities. The thermal black process uses methane as a feedstock. A pair of furnaces ...
