【摘要】A novel technology of preparing zeoliltes based on solid-solid mass transformation mechanism is developed for the first time. By employing this technology, three different types of highly crystallized pentasil

zeolites,ZSM-35

(FER-type),

Silicalite-l(MFI-type)

and

Mordenite(MOR-type), are successfully synthesized in the solid system. In terms of commercial production, the technology'could simplify synthesis procedure and make the continuous production of zeolites possible, so as to improve the productivity. Additionally, it is environmentally friendly because the crystallization occurs in solid phase where there exists no pollution caused by waste liquid. Therefore, this technique provides us with a new indusr, rial process for the clean and continuous production of zeolites.The characteristics in synthesis chemistry and the crystallization mechanism involved in the technology are also discussed. 【总页数】4页(P.656-659)
