Abstract
Provided is a method which is for producing methanol and which achieves high catalyst stability over time. This method for producing methanol includes the step of bringing a raw material gas into contact with a catalyst to obtain methanol, the raw material gas containing a carbon oxide and hydrogen, the catalyst containing (i) copper and zinc at a molar ratio of the zinc relative to the copper (Zn/Cu) of 0.3 to 0.45, and (ii) an alkali metal in an amount of 0% by mass to 0.05% by mass.
