文摘
- •
MCM-49 zeolites are simultaneous recrystallized and post-synthesized by TEAOH/piperidine.
- •
The total acid sites of recrystallized MCM-49 have been improved by at least 60%.
- •
The morphology of recrystallized MCM-49 is tailored into small irregular sheets.
- •
The ethylene conversion is enhanced with high EB selectivity.
