Abstract
The present invention provides a method for producing carbon black and an apparatus therefor, in which a gasification furnace is separated into a lower gasification section and an upper pyrolysis section via a distribution plate, waste tire chips are supplied to the pyrolysis section of the gasification furnace and pyrolytically decomposed to separate it into pyrolysis gas and fixed carbon, fine fixed carbon is separated from a mixed gas discharged from the gasification furnace and supplied to the gasification section of the gasification furnace to generate gasification gas, the gasification gas is supplied to the pyrolysis section through the distribution plate, a mixed gas of pyrolysis gas and gasification gas is introduced after fine fixed carbon is separated, so that carbon black is yielded.
