ABSTRACT:
A process for producing carbon black by thermally decomposing a hydrocarbon starting material in a production furnace by introducing the starting material to a high temperature zone heated by a high temperature combustion gas formed by burning a fuel and an oxygen-containing gas by a high temperature combustion gas-generating burner, characterized in that an alkali metal compound and/or alkaline earth metal compound is (A) introduced from alkali burner, burner specially itemed for ionizing the alkali metal compound and/or alkaline earth metal compound, set independently from said high temperature combustion gas-generating burner, for burning a mixture of a fuel and an oxygen-containing gas, or (B) ionized in an ionizing furnace specially itemed for ionizing the alkali metal compound and/or alkaline earth metal compound, and then introduced to the production furnace.
