Abstract

The invention relates to a process for the parallel preparation of hydrogen, carbon monoxide and a carbon-comprising product, wherein one or more hydrocarbons are thermally decomposed and at least part of the pyrolysis gas formed is taken off from the reaction zone of the decomposition reactor at a temperature of from 800 to 1400° C. and reacted with carbon dioxide to form a gas mixture comprising carbon monoxide and hydrogen (synthesis gas).
