ABSTRACT:
A process for producing carbon black comprises combustion of a fuel with air to form a stream of products of complete combustion of the fuel, whereinto a hydrocarbon feedstock is then added. The hydrocarbon feedstock is decomposed by absorption of heat from the combustion products, with the formation of a carbon black containing effluent. A portion of the carbon black containing effluent is collected and the remaining portion of the carbon black containing effluent is quenched by introducing a cooling agent thereinto. Thereafter carbon black is recovered from the remaining portion of the carbon black containing effluent. The collected portion of the carbon black containing effluent is fed, according to the invention, into the combustion chamber as fuel.
