PROBLEM TO BE SOLVED: To provide a catalyst having high activity and long term durability in the synthesis of methanol by the reaction of a carbon oxide with hydrogen. SOLUTION: The methanol synthetic catalyst consists essentially of copper oxide, zinc oxide, aluminum oxide, silicon oxide and cerium oxide, and preferably contains zirconium as an optional component. Silicon oxide originates from colloidal silica or dissolved silica in water. The catalyst is previously treated with calcining at 480-690 deg.C. |
