AbstractMethanol conversion over SAPO molecular sieve DNL-6 was investigated from the view point of the reaction mechanism. The organic materials confined in the cavities of DNL-6 were mostly polymethylbenezenes. By combination of in situ NMR study with ex situ GC-MS measurements, the structure of heptamethylbenzenium ion (heptaMB(+)) formed during MTO reaction was definitely confirmed. Further evidences from the mass spectra and C-13 solid-state NMR spectra in the isotopic switch experiments showed that the side chain methylation mechanism was the main reaction route for olefin formation from hydrocarbon pool species.
