B-Si-ZSM-12型分子筛的合成及其结构和性能的研究
STUDIES ON SYNTHESIS, PROPERTIES AND STRUCTURE OF B-Si-ZSM-12 ZEOLITES
【摘要】 <正> ZSM-12型分子筛是七十年代初开发的一种高硅分子筛,它具有独特的孔道结构、良好的催化性能和应用前景。在这方面虽已有不少的研究工作,但全部取代的杂原子ZSM-12型分子筛还未见报道。本文系统地研究了在NaOH-MTEACl-H3BO3-SiO2-H2O体系中合成B-Si-ZSM-12型分子筛以及各种因素对合成的影响,测试了该分
【Abstract】 B-Si-ZSM-12 zeolites were synthesized by hydrothermal crystallization of SiO2,-H3BO3-MTEACl-NaOH-H2O system. Effects of the composition of reaction mixture, the reaction temperature and reaction time on crystallization were investigated. XRD, IR and B11MAS-NMR spectroscopy were used to study the structure of the zeolites.The adsorption capacity and thermal stability of the zeolites were also studied.
