Abstract
The invention relates to a method for producing hydrogen and pyrolytic carbon from hydrocarbons, wherein the hydrocarbons are converted into hydrogen and carbon in a reactor at a temperature of 1000° C. or higher, and the reactor has at least two electrodes which are spaced apart from one another in the flow direction of the hydrocarbons. In order to avoid carbon deposits in the region between the two electrodes, which could lead to malfunctions of the heating system, in the method carbon particles are introduced into the reactor in countercurrent with the hydrocarbons and heated in the region between the electrodes to a temperature above the decomposition temperature of the hydrocarbons at a mass flow rate such that a reaction zone in which the hydrocarbons are converted into hydrogen and carbon is spatially separated in the flow direction of the carbon particles from a heating zone located between the electrodes.
