ELECTROLYTIC GENERATION OF GRAPHITE

摘要

The embodiments herein relate to methods and apparatus for forming graphitic material from a carbon oxide feedstock in an electroplating chamber containing molten inorganic carbonate as electrolyte. Carbon dioxide flows into a reaction chamber containing one or more cathodes, one or more anodes, and a molten carbonate electrolyte. The carbon dioxide and/or carbonate reduces at the cathode to form graphitic material, which may be removed from the surface of the cathode through various mechanisms. The graphitic material is then separated out from the electrolyte.

主权项

1. A method of producing carbon, the method comprising:
reducing a precursor comprising carbon dioxide and/or carbonate ion to solid carbon by contacting the precursor with a cathode in an electrochemical cell containing a molten inorganic carbonate as electrolyte; removing the solid carbon from the cathode, wherein the solid carbon forms a mixture with the electrolyte; and separating the solid carbon from the electrolyte.
