摘要

PPROBLEM TO BE SOLVED: To provide a method of preparing a catalyst for synthesis of methanol which catalyst shows a reduced tendency of lowering of the activity, compared with conventional catalysts for low-temperature liquid-phase synthesis of methanol, even when the raw material gas for synthesis of methanol involves carbon dioxide, water, etc. and exerts a higher catalytic activity and a method of synthesizing methanol in a liquid phase by using the catalyst prepared by the method. PSOLUTION: The method of preparing the catalyst for synthesis of methanol is used in a liquid-phase methanol synthetic reaction in which methanol is synthesized from a raw material gas containing carbon monoxide and hydrogen in the presence of an alcohol solvent. In drying a precipitation obtained from an aqueous solution of a copper (Cu) type catalyst ingredient and a precursor substance of the second catalyst ingredient by coprecipitation, the precipitation is brought in contact with a supercritical fluid.
