| 中文摘要 | conversion of methanol over h-zsm-22: the reaction mechanism and deactivation |
| 英文摘要 | conversion of methanol to olefins (mto) over h-zsm-22 was carried out in the pulse and the continuous-flow reaction systems. (13)c labeling technique was used to reveal the reaction mechanism. the materials retained in the deactivated catalyst were detected by gc-ms after dissolving the catalyst framework and then extracting the organic species. the adsorption of these materials in zsm-22 channels was computationally modeled. the results showed that the olefin methylation-cracking mechanism is the main route for the conversion of methanol over h-zsm-22. it was suggested that the blockage of the zeolite pore openings by the coke species might be the reason of the relatively rapid deactivation of h-zsm-22, instead of the prohibition of the formation of large transition-state intermediates involved in hydrocarbon pool mechanism.
