ABSTRACT:
Disclosed is a novel high color carbon black having an electron microscope surface area over 250 m.sup.2 /g and a nitrogen adsorption surface area between about 240 and about 500 m.sup.2 /g and a novel furnace carbon black having an electron microscope surface area above 250 m.sup.2 /g and a nitrogen adsorption surface area below about 800 sq. m/g. Also disclosed is a process for making these high color carbon blacks comprising feeding into a carbon black reactor a carbonaceous feed which is cracked at a high temperature to produce carbon black, wherein the reaction producing carbon black is at least quenched partially by contacting the reaction products directly with an auxiliary fuel taken from the group comprising a high BTU gas and a vaporizable hydrocarbon oil.
