英文摘要	the heptamethylbenzenium cation (heptamb(+)) has been speculated to be one of the most important active intermediates involved in the "hydrocarbon pool" mechanism of methanol-to-olefin (mto) conversion. by the use of dnl-6, a newly synthesized sapo-type molecular sieve with large cavities, heptamb(+) has for the first time been directly observed during methanol conversion under real working conditions. c-13-labeling experiments suggested that olefin formation mediated by heptamb(+) mainly follows the side-chain mechanism.
