摘要
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-2-4(=) selectivity.
