ABSTRACT:
An apparatus for producing carbon black by pyrolytic decomposition of coal with hot combustion gases. In a cylindrically shaped vertical reactor coal is tangentially introduced, thus establishing a helically flowing mass of pulverized coal. This mass is contacted with hot combustion gases. Fine ashes are withdrawn from the upper portion of the reactor at the periphery and coarse ashes are withdrawn from the lower portion of the reactor from the periphery. Carbon black-containing gases are withdrawn from the area of the vertical axis of the reactor overhead.
