Abstract: A method for producing methanol includes dissolving carbon dioxide in water to obtain a two-phase coexistence aqueous solution that is pressurized and heated to a critical state to separate critical state carbon dioxide and critical water. The critical state carbon dioxide is reduced to critical state carbon monoxide. The critical water is electrolyzed to obtain super critical state hydrogen and super critical state oxygen. The critical state carbon monoxide reacts with the super critical state hydrogen to produce methanol. Furthermore, a device for producing methanol is also provided in the present invention, comprising a mixing unit, a conversion unit and a synthesis unit, and which is highly effective in producing methanol and frugal in energy use.
