- the organic salts dissolved in this way are subsequently converted electrochemically.
- the cations contained in the electrolytic solution are preferably ions of
- Alkali metals in particular potassium ions and / or sodium ions.

Furthermore, potassium and sodium ions with the organic compounds form readily water-soluble organic salts and thus electrochemically
- Potassium ions are also particularly suitable because the hydrate shell forming around them in aqueous solution is smaller than those which are present to form sodium ions.

- Electrolyte solution in the flow cell 2 the temperature and / or the pH and / or the ion concentration of the electrolyte solution and the current and the voltage of the voltage source 9. These process parameters are previously set or adjusted so that the present in the electrolyte solution in each case Connections via redox reactions at the electrodes 6a, 6b of the electrode assembly 6 are converted into a gaseous fuel. In the course of this conversion, the molecules of the organic compounds contained in the electrolyte solution are therefore fragmented and defunctionalized.

- Invention is understood by a synthesis gas suitable for the synthesis of other organic compounds gas mixture, which consists mainly of carbon monoxide and hydrogen. From the synthesis gas formed further organic compounds can be prepared in a conventional manner. In particular, synthesis gas for Fischer-Tropsch synthesis can be used. Another possible use of the synthesis gas is, for example, in its conversion to methanol.
- sulfur atoms are, for example, oxidized to sulfate and nitrogen atoms in particular converted to nitrites, nitrates, ammonia or nitrogen molecules.
