Hierarchical SAPO-34 crystals were synthesized by a facile TEAOH etching post-treatment for the first time. Owing to the diffusion intensification and unchanged catalytic activity, the single-run lifetime of the resultant zeolites was significantly prolonged in the MTO process from 320 to 640 min without sacrificing the excellent methanol conversion and C![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
2–4 selectivity.
