PROBLEM TO BE SOLVED: To achieve a long life and high activity and raise heat resistance by a method wherein when a methanol reforming catalyst is manufactured, a copper compound, a zinc compound, and an aluminum hydroxide are used, a precipitate is generated by mixing with alkali substance, and the generated precipitate is separated and burnt. SOLUTION: When a catalyst to be used in the case of manufacturing a reformed gas having hydrogen as a main constituent by allowing methanol to react on water vapor, aluminum hydroxide is firstly added to aqueous liquid containing a copper compound and a zinc compound, this mixed liquid is dropped into alkali substance aqueous liquid kept at about 800 deg.C while stirring, and a precipitate is generated. Then, after washing the generated precipitate by water, it is filtered, dried, and burnt with in a temperature range of 300 to 650 deg.C to obtain a sinter compact. Thereby, even at a high reacting temperature and in a high methanol feed speed condition, a catalyst having high activity and a long life is obtained. Further, as occasion dempands, a burning treating material is treated by hydrogen reduction at 150 deg.C or higher and not higher than 300 deg.C. |
