- •
Phosphate-modification of MCM-68 enhanced propylene yield up to 50 C-atom % in DTO reaction.
- •
The external acid sites on dealuminated MCM-68 were selectively deactivated.
- •
Phosphate-modified MCM-68 achieved propylene/ethylene ratio as high as 42.
- •
The prepared catalyst efficiently improved coke durability.
