PROBLEM TO BE SOLVED: To provide a catalyst with a high methanol-refining property. SOLUTION: When a sufficient heating is carried out to the methanol-refining catalyst comprising a Pt-Ru system alloy powder, a sintering is advanced and a shape approaches a true sphere. A particle diameter becomes large and a specific surface area become small, however, a crystallinity is enhanced. Therefore, a methanol-refining property becomes higher. |
