- •
We synthesized SAPO-34 and its modified samples with different five metal ions.
- •
Metal incorporation gave rise to the different micropore area and acidity.
- •
All the SAPO-34 and MeAPSO-34 samples are active and selective in MTO process.
- •
Metal incorporation improved the catalyst lifetime and favored light olefin yield.
- •
The order of increasing in lifetime increased as Ce- > La- > Co- > Ni- > Fe- > SAPO-34.
