- •
This work could synthesize NS-MFI catalysts optimized for MTP reaction.
- •
The MTP activity and catalyst lifetime improved by the mesoporosity of NS-MFIs.
- •
The thinner thickness of NS-MFI catalyst was preferable in view of the catalyst life.
- •
Correlation between the coking and Si/Al2 ratio of NS-MFIs could be explained by acid site dispersion.
- •
This paper suggested the optimized NS-MFI catalysts can greatly improve MTP process efficiency.
