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° F.-1500° F. prior to use whereby it acquires activated sites not present in mordenite calcined at lower temperature.
