Methanol production method
This method produces methanol with reduced dependency on fossil fuel. The method includes: a gas acquisition step of acquiring a gas (G 1 ) containing hydrogen by a pyrolysis reaction and/or a dehydrogenation reaction of a hydrocarbon; and a conversion step of converting at least part of the gas (G 1 ), and a source gas containing (G 2 ) carbon oxide into methanol. In the conversion step, the reaction is allowed to proceed by condensing a high boiling point component containing converted methanol and water, and discharging the high boiling point component condensed to the outside of the reaction system.
1 . A methanol production method, comprising:
a gas acquisition step of acquiring a gas containing hydrogen by a pyrolysis reaction and/or a dehydrogenation reaction of a hydrocarbon; and
a conversion step of converting a source gas containing at least a part of the gas and carbon oxide into methanol, wherein
in the conversion step, the reaction is allowed to proceed by condensing a high boiling point component containing converted methanol and water, and discharging the high boiling point component condensed to an outside of a reaction system, and
the method further comprises a combustion step of burning a byproduct produced in the gas acquisition step, wherein carbon oxide obtained in the combustion step is used as a part of the source gas.
2 . The methanol production method according to claim 1 , wherein the gas acquisition step includes a dehydrogenation reaction of propane.
3 . The methanol production method according to claim 1 , further comprising, between the gas acquisition step and the conversion step, a reforming step of reforming at least a part of a hydrocarbon produced as a byproduct in the gas acquisition step into carbon oxide and/or hydrogen.
