Abstract:
The invention relates to a method for generating syngas (5). Hydrocarbon (2) is thermally decomposed into hydrogen and carbon in a first reaction zone (Z1), and hydrogen produced in the process is conducted from the first reaction zone (Z1) to a second reaction zone (Z2) in order to react the hydrogen with carbon monoxide (4) in the second reaction zone so as to produce water and carbon monoxide. The invention is characterized in that the energy required for the thermal hydrocarbon decomposition in the first reaction zone (Z1) is supplied from the second reaction zone (Z2).
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).
Abstract:
The invention relates to a method for the parallel production of hydrogen and of one or more carbon-containing products. In the method, hydrocarbons are introduced into a reaction chamber (R) and are thermally decomposed into carbon and hydrogen in the presence of a carbon-rich granulated material (W). The invention is characterised in that at least a portion of the thermal energy necessary for the decomposition of the hydrocarbon is introduced into the reaction chamber (R) via a gaseous heat transfer medium.
