ZSM-35沸石原位固相转化法合成过程控制
Control of process for synthesis of ZSM- 35 zeolite by in- situ solid phase transformation method
摘要
Abstract
Using ethylenediamine (EDA) as template agent,ZSM -35 zeolite was prepared by in -situ solid phase transformation method. The influences on crystallization process as well as crystallization mechanism were investigated in detail by XRD method. Results showed that the proper silicon - aluminum molar ratio n( SiO2 )/ n(Al2O3) for synthesis of ZSM -35 zeolite is 21 ~ 37; both Na+ and EDA play a cooperative structure -orientation role in the synthesis of ZSM - 35 zeolite; suitable time for crystallization is 14 ~ 21 h, while extension of crystallization time tends to change ZSM - 35 zeolite into ZSM - 5 zeolite. Results of study on crystallization mechanism indicated that the synthesis process displays features of solid phase crystallization mechanism. Since both ZSM -35 zeolite and ZSM -5 zeolite have same secondary structural units, they are easily to transform each other in the crystallization process.关键词
