Abstract
Improvements introduced in the production process of carbon black, whose process regulates the surface area of the carbon black, during its production in the furnace, preparing said carbon black by decomposition of a hydrocarbon feed material in the presence of hot combustión gases and of an alkaline-earth metal, whose improvements are characterized in that they comprise, in combination, the steps consisting of carrying out said decomposition by admitting hot combustión gases in a first zone in which said feed material is injected, mixing said material with turbulence. Of feed and said hot combustión gases and introducing them into a second zone through a separation of a choke having a cross section less than that of any one of said zones, injecting an alkaline-earth metal chosen from the group that includes calcium, strontium and magnesium as well as their mixtures, in the turbulent reaction loop resulting in said second zone, in cooling said reaction mass below the reaction or dissociation temperature at a certain distance downstream from the injection point of said alkaline earth metal and in collecting the resulting product.
