    Abstract: A process of making carbon black in a cylindrical reaction chamber containing a preheating zone and a combustion zone comprises passing a hydrocarbon-containing gas through the preheating zone out of contact with other gases and then passing the gas through a revolving cylinder of free oxygen-containing gas in the combustion zone. Hydrocarbon gas, with or without air, which may be heated in separate preheater 26 is passed into a cylindrical reaction chamber 10 of the type described in Specification 621,031, having a refractory, e.g. sillimanite or "Alundum" (Registered Trade Mark), lining 11, enclosed in insulation 12 and steel shell 13, through refractory, e.g. "Carborundum" (Registered Trade Mark) tube 17 containing a lug supported refractory, e.g. "Carborundum," alumina, fused quartz, or sillimanite, core 18 which may be shorter than tube 17 and cylindrical or X-shaped. One or more tangential burners 15a, 15b, admit air and fuel gas to produce a helical layer of flame and combustion products along the chamber wall preheating the hydrocarbon feed gas in tube 17 to say 1800-2000 DEG F. with cracking to 8-10 per cent olefin content. Once the reaction is proceeding air alone may be admitted at 15b and the effluent gas is cooled by spray 27.
