Abstract
- The catalytic performance of MCM-22 zeolites in n-hexane cracking has been investigated at high n-hexane conversions.
- The relationship between the catalytic performance and the acid properties has been investigated.
- MCM-22 zeolites with higher Si/Al ratios exhibited better catalytic performance due to the lower amount and strength of acid sites.
- Dealuminated MCM-22 zeolites by using ammonium hexaflurosilicate (AHFS) treatment showed the higher catalytic life and propylene selectivity at very high n-hexane conversions, due to the smaller amount of Lewis acid sites.
