Abstract
duced into the zeolite by ion-exchanging it with an aqueous solution containing the metal ion. Isomerization activity leveled off to a maximum at some metal content, whereas that of hydrogenolysis increased with increasing metal content with the exception of Pd/HY. The order of maximum isomerization activities of the catalysts was as follows: Pt/HY>Pd/HY, Rh/HY>Ir/HY>Ni/HY>Co/HY>Ru/HY>Fe/HY The order of hydrogenolysis activities was as follows: Ru/HY>Rh/HY>Ir/HY>Pt/HY>Pd/HY; Co/HY> Ni/HY>Fe/HY From these results, Pd/HY and Pt/HY were found to be the most active and selective among Group VIII metal/HY catalysts for isomerization of n-pentane to isopentane. Finally, the mechanism of isomerization of n-pentane was discussed on the basis of the present experimental results.
