    Abstract: Methanol is economically produced from carbon dioxide in a high yield by a process which comprises compressing a gaseous mixture of carbon dioxide and hydrogen; introducing the compressed gaseous mixture into a conversion column; converting a part of the carbon dioxide contained in the mixture to carbon monoxide in the presence of a catalyst in the conversion column to produce a gas phase mixture and a liquid phase mixture; removing the liquid phase mixture in a gas-liquid separator; introducing the gas phase mixture from the gas-liquid separator into a reactor while recycling, optionally, a part thereof into the conversion column; reacting the compressed gas phase mixture introduced into the reactor in the presence of a catalyst to produce a mixture containing methanol; and recovering methanol as a liquid phase product from the mixture.
