Claims
- 1. A zeolite or molecular sieve, said zeolite or molecular sieve having an AAI of at least 1.0.
- 2. The zeolite or molecular sieve of claim 1 wherein said zeolite or molecular sieve has pores which have an average pore diameter greater than 100 Angstroms.
- 3. The zeolite or molecular sieve of claim 1 wherein said zeolite or molecular sieve has a pore volume greater than 0.7 cm3/g.
- 4. The zeolite or molecular sieve of claim 1 wherein silica and alumina are present in a silica to alumina molar ratio of at least 6:1.
- 5. The zeolite of claim 4 wherein the zeolite is selected from the group consisting of beta, TEA-mordenite, TEA-ZSM-12, MCM-22, PSH-3, ZSM-5, TPA-5, Breck 6.
- 6. The zeolite of claim 4 wherein the zeolite is produced using an organo-nitrogen directing agent.
- 7. The zeolite of claim 6 wherein the silica to alumina molar ratio is at least 15:1.
- 8. A process for converting a chemical, comprising:
effecting said conversion in the presence of a catalyst comprising the zeolite or molecular sieve of claim 1.
- 9. The process of claim 8 wherein the conversion is an aromatic alkylation.
- 10. The process of claim 9 wherein the zeolite is selected from the group consisting of zeolite beta, MCM-22 and PSH-3.
- 11. The process of claim 8 wherein the conversion is hydroisomerization.
- 12. The process of claim 8 wherein the conversion is hydrocracking.
- 13. The process of claim 8 wherein the conversion is the removal of nitrogen oxide.
- 14. The process of claim 8 wherein the zeolite is the zeolite of claim 2.
- 15. The process of claim 8 wherein the zeolite is the zeolite of claim 3.
- 16. The process of claim 8 wherein the zeolite is the zeolite of claim 4.
- 17. The process of claim 8 wherein the zeolite is the zeolite of claim 5.
- 18. In a process for producing a zeolite or molecular sieve wherein said process includes removal of an organic templating agent, the improvement comprising:
removing said templating agent at a temperature of no greater than 550° C. and under conditions wherein after the removal of the templating agent, said zeolite or molecular sieve has an AAI of at least 1.0.
- 19. The process of claim 18 wherein at least 50% of the templating agent is removed.
- 20. The process of claim 19 wherein the zeolite is selected from the group consisting of beta, TEA-mordenite, TEA-ZSM-12, MCM-22, PSH-3, ZSM-5, TPA-5, Breck 6.
- 21. The process of claim 19 wherein the heating is in a bed in which heating is controlled to prevent a temperature variation in the bed of more than 25° C. from the average bed temperature.
- 22. The process of claim 21 wherein the heating rate is less than 10° C./min.
- 23. The process of claim 18 wherein after removal of the templating agent, said zeolite or molecular sieve has pores which have an average pore diameter of greater than 100 Angstroms.
- 24. The process of claim 18 wherein after removal of the templating agent said zeolite or molecular sieve has a pore volume greater than 0.7 cm3/g.
