PROBLEM TO BE SOLVED: To obtain a methanol synthesizing catalyst having high activity and excellent in durability by adding respective oxides of copper, zinc, aluminum and zirconium and further adding oxide of one or more kinds of a metal among gallium, manganese and indium. SOLUTION: This catalyst for synthesizing methanol from synthetic gas based on hydrogen and carbon monoxide is prepared by adding at least respective oxides of copper, zinc, aluminum and zirconium and further adding oxide of one or more kinds of a metal among gallium, manganese and indium. The pref. compsn. ratio (atomic ratio) of this methanol synthesizing catalyst is set to Cu:Zn:A:Zr:(α)=100:10-200:1-20:1-20:1-20 and (α) is one or more kinds of a metal among Ga, Mn and In. By using this catalyst, methanol can be synthesized stably over a long period of time. |
