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, silica to alumina mole ratio in the range of 10:1 to 20:1, 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.
