ABSTRACT:
A process for producing a relatively coarse, highly structured carbon black having a large surface area. The method comprises mixing a hydrocarbon feedstock with hot combustion gases at a high temperature in a reaction chamber wherein turbulence and stream velocity are relatively low in order to produce a preliminary coarse carbon black and effluent gases. The produced coarse carbon black is subsequently separated from the effluent gases. The separated produced carbon black is thereafter fed into a reaction chamber wherein turbulence and residence time are specifically controlled. Subsequently, the separated and produced carbon black is oxidized under controlled conditions within the reaction chamber with hot combustion gases in order to produce a coarse, large surface area, highly structured carbon black product and effluent gases. The effluent gases are thereafter separated from the coarse, high surface area, highly structured carbon black product.
