1. A methanol production system, comprising:
a reformer including a reaction furnace configured to reform methane in a raw material gas to produce a reformed gas containing CO and Hz;
a reduced-gas generator configured to reduce CO2 to produce a reduced gas containing CO;
a methanol-containing gas generator configured to produce a methanol-containing gas which contains methanol from a reformed gas produced in the reaction furnace and the reduced gas produced in the reduced-gas generator; and
a carbon dioxide separator configured to separate out the CO2 from exhaust gas,
wherein the reformer further includes a combustion furnace configured to supply heat generated through burning of a fuel gas to the reaction furnace and to produce the exhaust gas through burning of the fuel gas, and
the methanol production system further comprises a hydrogen supply path through which H2 is introduced from the methanol-containing gas generator into the combustion furnace.
