Description

Description of the invention Claim 1. Methane can be synthesized from carbonated water using a photocatalyst. Claim 2. Methane can be synthesized by injecting CO2 into high-pressure seawater. Claim 3. Methane can be synthesized by using carbonated water with a metal catalyst. [Brief explanation of the drawings] [Figure 1] Methane can be synthesized by adding C to carbonated water A in a container and applying B to it. [Figure 2] CO2 is injected into the pressurized seawater placed in A by B, and the methane produced in C is extracted. [Figure 3] Carbonated water A in a container can be mixed with B to produce C. If we accurately express claim 2 in the description of the invention, methane can be synthesized by the action of sodium chloride and high pressure on water as a catalyst. I would like to revise this, but to do so I would have to rewrite the specification itself, so I created it as instructed in the amendment. end
