发明名称 METHOD FOR PRODUCING CARBON BLACK
摘要 <p>A method for producing carbon black by means of a horizontal carbon black production furnace comprising a first reaction zone in which a mixture of an oxygen-containing gas and a fuel is burned to form a high temperature gas stream, a second reaction zone in which a hydrocarbon feedstock is supplied and reacted to the high temperature gas stream formed in the first reaction zone, and a third reaction zone in which quenching water is sprayed to the gas mixture from the second reaction zone to terminate the reaction, wherein the second reaction zone is constructed to have a hollow cylindrical structure with at least two cylindrical sections having different inner diameters connected to one another and the hydrocarbon feedstock is divided for supply so that it be supplied to at least two locations including an upstream cylindrical section to which the hydrocarbon feedstock is first supplied and a cylindrical section located downstream thereof and so that the flow velocities of gases passing through the respective cylindrical sections be thereby mutually differentiated within a range of from 100 to 500 m/sec.</p>
