PURPOSE:To enhance the activity and selectivity of a methanol reforming catalyst and to extend the life thereof, by preparing the methanol reforming catalyst by containing copper, nickel and silicon formed by a coprecipitation method. CONSTITUTION:Hydroxide or carbonate of an alkali metal element or an alkaline earth metal element is mixed with an aqueous solution containing compounds of copper, nickel and silicon as a precipitant as it is or as an aqueous solution or in a form mixed with aqueous ammonia to prepare a precipitate. Subsequently, the precipitate is aged, filtered off and washed while the washed precipitate is dried pref. at 100-120 deg.C and subsequently baked pref. at 300-600 deg.C. If necessary, the baked precipitate is molded into a tablet with a proper size and reduced pref. at 200-500 deg.C under an atmosphere of hydrogen, carbon monoxide or a gaseous mixture thereof to prepare a methanol reforming catalyst. |
