| 英文摘要 | zsm-34 (off/eri intergrowth) was synthesized using choline chloride as the template in a shorter crystallization time under hydrothermal conditions. many factors that may influence the synthesis were investigated. the eri content in zsm-34 could be adjusted by selecting different synthesis conditions. the synthesized products were characterized by x-ray diffraction, scanning electron microscopy, and x-ray fluorescence spectroscopy. adsorption experiments showed that zsm-34 possessed high pore volume, and the adsorption amount of n-hexane reached 11.4%. in the methanol- to-olefins reaction, hzsm-34 exhibited high selectivity for ethylene. the maximum selectivity for total olefins (c2h4 + c3h6) over hzsm-34 was 86. 0 , and it nearly did not change even when the methanol conversion decreased. high- temperature steam treatment increased the framework si/al ratio and thus decreased the acidity of hzsm-34, which led to the obvious decrease in propane selectivity and the increase in initial olefins selectivity. |
