摘　　要：以EU-1分子筛为异质晶种，采用不同模板剂和硅源合成两种不同粒度尺寸的ZSM-11分子筛。采用XRD，FT—IR，SEM，Nz吸附-脱附等手段对合成的ZSM-11分子筛样品进行表征。结果表明，当晶种加入量（W）为1％～10％时，一定温度下水热晶化处理1～10天，均可以得到结晶度高、无杂晶的ZSM11分子筛。采用不同方法合成的两种ZSM11分子筛在形貌、晶粒尺寸及硅铝比上存在较明显区别，微米尺寸的ZSM11分子筛呈椭球状，由许多板条状粒子团聚而成，尺寸约为200nm×700nm，硅铝比较高；纳米尺寸的ZSM—11分子筛为清晰的球状晶体，是由许多球状纳米级粒子团聚形成的，粒径在100nm以下，硅铝比较低。With zeolite EU-1 as heterogenous crystal seed, two ZSM-11 zeolite samples having different crystal sizes were synthesized by using different synthesis methods, templates and silicon sources. The prepared ZSM-11 samples were characterized by XRD, FT-IR, SEM, N2 adsorption-desorption and so on. The influence of the adding amount of heterogenous crystal seed was studied. Results showed that zeolite ZSM-11 with high crystallinity could be obtained when using 1%--10% heterogenous crystal seed and crystallization under a certain temperature for 1--10 days. The characterization results showed that the morphologies and crystal size of ZSM-11 samples synthesized by different methods were varied：one exhibited as spherical nanometer crystals with particle size under 100 nm,and another was elliptic globosity micron crystals（200 nm × 700 nm）having large mesoporous structure,which was agglomerated by panel particles. Furthermore,the SiO2/Al2O3 ratios of these two samples varied significantly as well,the nanometer sample was lower and the micron one was higher.
