Title:
METHOD FOR PRODUCING METAL CARBIDE, METHOD FOR PRODUCING HYDROCARBON, AND METAL CARBIDE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/058619
Kind Code:
A1
Abstract:
Provided are: a method for producing a metal carbide using carbon dioxide as a carbon source and a metal oxide as a metal source; a method for producing a hydrocarbon from the metal carbide obtained using carbon dioxide as a carbon source and a metal oxide as a metal source; and a metal carbide composition. This method for producing a metal carbide includes: preparing a molten salt containing a first metal oxide; adding carbon dioxide to the molten salt; applying voltage to the molten salt containing the carbon dioxide; and obtaining a precipitate containing a carbide of the first metal. Furthermore, this method for producing a hydrocarbon includes hydrolyzing a carbide of the first metal so as to obtain a hydrocarbon-containing gas and a hydroxide of the first metal.
