Abstract

Official abstract text for this publication.

A method for producing a hydrocarbon including: preparing a molten salt containing a carbonate of a first metal; obtaining precipitates containing a first metal carbide by applying a voltage to the molten salt; and obtaining a gas containing the hydrocarbon and a hydroxide of the first metal by hydrolyzing the first metal carbide.

First claim

Opening claim text (preview).

1 . A method for producing a metal carbide, comprising: preparing a molten salt containing a carbonate of a first metal contains at least one selected from the group consisting of alkali metals and alkaline earth metals; and obtaining precipitates containing a first metal carbide by applying a voltage to the molten salt. 2 . The method for producing a metal carbide according to claim 1 , wherein the molten salt further contains a halide of a second metal. 3 . The method for producing a metal carbide according to claim 2 , wherein the first metal and the second metal are the same. 4 . The method for producing a metal carbide according to claim 2 , wherein halogen in the halide contains chlorine. 5 . The method for producing a metal carbide according to claim 2 , wherein the halogen in the halide contains fluorine. 6 . The method for producing a metal carbide according to claim 1 , wherein the precipitates further contain at least one selected from the group consisting of carbon, the simple substance, halide, carbonate, oxide, hydride, and peroxide of the first metal, and the simple substance, halide, carbonate, oxide, and carbide of a metal other than the first metal contained in the molten salt. 7 . The method for producing a metal carbide according to claim 1 , wherein the first metal contains at least one selected from the group consisting of lithium, sodium, potassium, and calcium. 8 . A metal carbide composition comprising: a first metal carbide as the main component; and further at least one selected from the group consisting of carbon, the simple substance, halide, carbonate, oxide, hydride, and peroxide of the first metal, and the simple substance, halide, carbonate, oxide, and carbide of a metal other than the first metal.
