Claim 7:
8. A methanol production method using the methanol production system according to claim 1, comprising:
a reaction step of oxidizing methane in a raw material gas to produce a reformed gas containing CO and H2;
a reduced-gas production step of reducing CO2 to produce a reduced gas containing CO; and
a methanol-containing gas production step of producing a methanol-containing gas which contains methanol from a reformed gas produced in the reaction step and the reduced gas produced in the reduced-gas production step,
a carbon dioxide separation step of separating out the CO2 from exhaust gas, and
a combustion step of generating heat used in the reaction step by burning a fuel gas to produce the exhaust gas through burning of the fuel gas,
wherein, in the combustion step, the excess H2 in producing the methanol-containing gas is further used to perform burning.
