摘要： 采用加入晶种的方法,在无定形相区中,研究晶体生长的规律,得出NH4-ZSM-5沸石晶体生长符合2/3级反应的结论。考察了影响晶体生长的各种因素,测定了晶体生长活化能,并且得出了晶体生长活化能与产物硅铝比的关系。

Abstract: By adding seed crystals of the zeolite NH4ZSM-5 the separation o nucleation and growth of NH4ZSM-5 was made to a certain extent. Under the approximately complete growth conditions the law on the growth of the crystals was investigated and it was shown that the growth of the crystals of zeolite NH4 ZSM-5 obeys a kinetic law of the order 2/3. The factors which influence the growth of crystals were examined and the apparent activation energies for growth of the crystals were obtained.The relation of Si/Al ratios of products to Apparent Activation Energies for growth of the crystals was also obtained.
