Abstract
Isomerization is effected at improved conversion and selectivity by use of a 0.5 w %-2.5 w % platinum-palladium group metal on hydrogen mordenite catalyst, the catalyst having been calcined at 1200.degree. F.-1500.degree. F. prior to use whereby it acquires activated sites not present in mordenite calcined at lower temperature.

The method which comprises
- loading a hydrogen mordenite having a silica-to-alumina mole ratio of 10-20:1, with a metal of the platinum-palladium group thereby forming a loaded hydrogen mordenite;
- calcining said loaded hydrogen mordenite at 1200.degree. F.-1500.degree. F. thereby forming a loaded calcined hydrogen mordenite containing activated isomerization sites;
- and
- recovering said loaded calcined hydrogen mordenite containing activated isomerization sites.
