Fund Project: This work was supported by the National Natural Science Foundation of China (21403279, 21507141, 21506243), and the Science and Technology Commission of Shanghai Municipality (14DZ1207602, 14DZ1203700).

Hierarchical SAPO-34 crystals were synthesized by a facile acid etching post-treatment. Butter-fly-shaped porous patterns on four side faces and hierarchical pores composed of micropores, mesopores and macropores were formed after a nitric acid or oxalic acid treatment. The catalytic performance of the hierarchical SAPO-34 for the methanol to olefins (MTO) process showed that the synergistic effect of the hierarchical pores and acid sites resulted in a longer catalyst lifetime (from 210 to 390 min for the acid treated SAPO-34) and higher selectivity to light olefins of 92%-94%. The ethylene selectivity can be adjusted between 37.4% and 51.5% by the pore size. No hierarchical SAPO-34 was obtained after a treatment with butanedioic acid, and with this sample, fast deactiva-tion was detected after 100 min.
