摘要： A novel technology of preparing zeolites 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-1(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 industrial 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.
