ABSTRACT:
A decomposition reactor for installation in connection with a thermal decomposition chamber for hydrocarbon gases, especially a plasma torch, is designed in the form of a defined, insulated chamber, with an inlet for admixtures/gases in the walls of the reactor space. In order to improve the control of the products produced, the supply channels in the walls of the reactor are provided with channels for introducing hydrocarbon gases of the same kind as the main medium introduced at a temperature of between 1,000 and 2,000.degree. C. in the upper region of the space. Hydrocarbon gas of a lower temperature is introduced at one or more points further down in the reactor. A method for the operation of such a decomposition reactor for the production of carbon black with defined physical properties, is also described.
