Claims
- 1. 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.
- 2. The method of claim 1 wherein said calcination is carried out at 1250.degree. F.-1350.degree. F.
- 3. The method of claim 1 wherein said calcination is carried out at about 1300.degree. F.
- 4. The method of claim 1 wherein said metal is palladium.
- 5. The method of claim 1 wherein said metal is palladium in amount of 0.5 w %-2 w %.
- 6. The method which comprises
- loading a hydrogen mordenite having a silica-to-alumina mole ratio of 10-20:1, with 0.5 w %-2.5 w % palladium thereby forming a palladium-on-hydrogen mordenite;
- calcining said palladium-on-hydrogen mordenite at 1200.degree. F.-1500.degree. F. thereby forming a calcined palladium-on-hydrogen mordenite containing activated isomerization sites; and
- recovering said calcined palladium-on-hydrogen mordenite containing activated isomerization sites.
- 7. The method which comprises
- loading a hydrogen mordenite having a silica-to-alumina mole ratio of 10-20:1 with 0.5 w %-2.5 w % platinum thereby forming a palladium-on-hydrogen mordenite;
- calcining the platinum-on-hydrogen mordenite at 1200.degree. F.-1500.degree. F. thereby forming a calcined platinum-on-hydrogen mordenite containing activated isomerization sites; and
- recovering said calcined platinum-on-hydrogen mordenite containing activated isomerization sites.
- 8. The method of claim 1 wherein said calcination temperature is 1250.degree. F.-1350.degree. F.
- 9. The method of claim 1 wherein the hydrogen mordenite catalyst is in the NH.sub.4 + form.
- 10. A catalyst composition prepared by 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.
- 11. A catalyst composition as claimed in claim 10 wherein said metal is palladium.
- 12. A catalyst composition as claimed in claim 10 wherein said metal is palladium in amount of 0.5-2.5 w%.
