ABSTRACT:
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.
