ABSTRACT OF THE DISCLOSURE The invention relates to a process for improving the degree of graphitization of carbon black produced by subjecting hydrocarbons which are liquid or gaseous under normal conditions to a thermal conversion reaction in the presence of oxygen or an oxygen-containing gas and steam, if desired, at temperatures of 1200 to 2000° C and pressures of 1 to 80 bars. To this end, the carbon black is conveyed downwardly in a quasi-fluid state, within 1 to 5 hours through a sojourn zone in upright position, the sojourn zone being maintained at a temperature of at least 1200° C. The invention also relates to an apparatus for carrying out this process, the apparatus comprising a graphite tube; a steel container concentrically surrounding the graphite tube; a feed pipe penetrating into the interior of the graphite tube; a water-cooled discharge means; and a nitrogen feed inlet arranged below the lower end of the graphite tube; the space left between the graphite tube and steel container being occupied by insulating material.
