ABSTRACT:
Disclosed is a method of producing carbon black by subjecting to a separation step a hydrocarbon feedstock containing a meltable solid, clarifying the hydrocarbon of the meltable solid and thereby making a concentrate of hydrocarbon and the meltable solid, and whereas the clarified hydrocarbon is introduced into the oil furnace process reactor to be converted to carbon black. The improvement lies in introducing the concentrate into the reaction zone of the reactor at a point where the temperature is below the melting point of the meltable solid. Carbon black is produced from the clarified oil and the oil concentrated with the meltable solid without substantially depositing the melted solid on the interior walls of the reactor.
