HYDROGEN PURIFICATION APPARATUS AND METHOD OF MANUFACTURING CO REMOVING CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen purification apparatus or the like having high CO removing efficiency through a long period.

SOLUTION: The hydrogen removing catalyst is manufactured by supporting at least one kind of a noble metal selected from Pt, Ru and Pd on a catalyst support formed from an oxide or a compound oxide contaning at least one kind of an element selected from Al, Si, Ti, Zr and Ce into a spherical form so that the difference between maximum and minimum diameters is ≤20% of the average diameter. The catalyst body 1 is a spherical structural body and the difference between the maximum diameter and the minimum diameter is controlled to ≤20% of the average diameter. Further the difference between the maximum diameter and the minimum diameter is controlled to ≥2% of the diameter.
