Abstract
The present invention provides a method for producing methanol making use of biomass material, which method is capable of making effective use of produced carbon monoxide without deteriorating efficiency of methanol production. The invention also provides an apparatus for producing methanol. In the method for producing methanol making use of biomass material including gasifying biomass to produce a gas and producing methanol from the produced gas, water is electrolyzed by means of a water electrolysis unit operated by electric power generated from a sunlight power-generation unit or a wind power-generation unit, and hydrogen gas generated through electrolysis of the water is supplied to the raw material gas such that the amount of hydrogen is adjusted to at least twice the amount of carbon monoxide contained in the produced gas, to thereby produce methanol in a methanol synthesis column.
