(57) [Summary] [Structure] In a hydrogen production method by steam reforming of methanol by a methanol steam reforming reaction, a catalyst component containing copper and zinc oxides or boron and / or aluminum oxides On the other hand, 0.5-10% by weight A catalyst containing diatomaceous earth is used. [Effects] The above catalysts have excellent strength, high activity, and little decrease in activity during long-term operation. Therefore, H 2 can be stably obtained in a high yield from methanol, and is industrially useful. H 2 is preferably produced. |
