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.

Decomposition of hydrocarbon to carbon black

In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the feed stock is passed through a plasma torch, which causes a pyrolytic decomposition of the feed stock. The feed stock is transported through the plasma torch (A) in a cooled lead-in tube (1) and undergoes a first heating in an area in the immediate vicinity of the plasma flame. The material thereby produced is passed on to one or more subsequent stages where the final and complete decomposition of the hydrocarbons to carbon black and hydrogen occurs. In this area further raw material may be added which causes quenching and reacts with the already produced carbon black. An increase is thereby caused in particle size, density and amount produced without further energy supply, whereafter the products produced are expelled and separated and hot gas may be transported in a return pipe to the torch, in order to further increase the energy yield.

Heat exchanger

Provided is a method for the reduction of electrode consumption in plasma torches during the processing and decomposition of hydrocarbons for the production of carbon black and hydrogen where hydrogen is supplied to the plasma torch as a plasma forming gas.
