摘要：

Fast synthesis of high-silica ZSM-5 zeolite through vapor-phase transport (VPT) method was reported in this paper. The synthesized samples were characterized with XRD, FT-IR, XRF, SEM and N-2 Absorption. Factors affecting the synthesis of ZSM-5 zeolite such as the alkalinity, the crystallization temperature and time, the quantity of seeds were investigated. With precipitated silica and fumed silica as silica source respectively, the appropriate ratio was studied as follows: (0.04-0.05) Na2O: 1.0SiO(2): 15H(2)O: (0-0.0046)Al2O3: 0.01Seed, the reaction was carried out at 393-413K for 4-24h.
