Process for producing carbon black

A process for producing carbon black in a reaction system comprising a first zone where a heating fuel material and an oxygen-containing gas are mixed, and a high temperature combustion gas stream is formed, a second zone where a hydrocarbon starting material is mixed to the high temperature combust...

Beschreibung
Zusammenfassung:A process for producing carbon black in a reaction system comprising a first zone where a heating fuel material and an oxygen-containing gas are mixed, and a high temperature combustion gas stream is formed, a second zone where a hydrocarbon starting material is mixed to the high temperature combustion gas stream to form carbon black, and a third zone subsequent to and down-stream of the second zone, where the carbon black thus formed, is contacted with an activating agent to activate the carbon black, characterized in that steam is introduced as an activating agent to the third zone.
