采用水热合成法,在合成过程中通过添加矿化剂、尿素和改变硅源,制备了不同骨架铝落位的ZSM-5分子筛.通过SEM、XRD、BET、XRF、MAS NMR、NH3-TPD和Py-FTIR等表征手段对分子筛的形貌、织构、骨架铝落位和酸性进行了系统研究,同时考察了不同ZSM-5分子筛催化剂甲醇制芳烃的催化性能.研究结果表明,制备的ZSM-5分子筛均具有结晶度高和形貌均一等特点,但在骨架铝落位和酸性方面存在显著差异.椭球状ZSM-5分子筛的骨架铝主要分布于直通孔道或正弦孔道中,并表现出较多的酸性位.块状分子筛中骨架铝主要落位在孔道交叉处,且具有较低的强酸量.在甲醇制芳烃反应中,骨架铝主要位于直通或正弦孔道并表现出较多酸性位的椭球状ZSM-5分子筛催化剂具有较高的活性稳定性和芳烃选择性.“,”ZSM-5 zeolites with different framework AI(AIF) siting were hydrothermally synthesized by adding mineralizer，urea，or by changing the silicon source. The morphology，textural properties，AIF siting，and acidity of different ZSM-5 zeolites were characterized using SEM，XRD，BET，XRF，MAS NMR, NH3-TPD，and Py-IR. Furthermore，the conversion of methanol to aromatics(MTA) was used to investigate the catalytic performance of different catalysts. The results suggested that different ZSM-5 zeolites were highly crystalline with a uniform morphology，but there were large differences in AIF siting and acidity. The AIF in the ellipsoidal ZSM-5 sample was mainly distributed in straight or sinusoidal channels and displayed more acidic sites. AIF of bulk ZSM-5 was mainly located at the intersection of channels，and it showed the lowest amount of strong acid sites. The ellipsoidal ZSM-5 catalyst in which AIF was mainly located in straight or sinusoidal channels exhibited more acidic sites and higher stability and aromatic selectivity during the MTA reaction.
