[交流] 求救:不含模板剂制备zsm-5

请问有没有人不用有机胺模板剂合成zsm-5分子筛的?

不用无机氨或有机胺,就是不用模板剂
按照南开大学的那篇专利根本做不出来,不知道是不是唬人的

加些沸石晶种,可以不使用模板剂。

Abstract
The MFI type of highly silica zeolite, ZSM-5 with well-defined crystal morphology was successfully synthesized in the absence of
organic template using two-step temperature process. In this process, the crystallization process was conducted at two different
temperatures by separating the nucleation and crystallization stage; that is, the nucleation stage at higher temperature (190 C) to
accelerate the nucleation followed by the crystallization stage at lower temperature (150 or 165 C) so as to control the crystal size
and size distribution. The effect of nucleation rate on the final crystal size and size distribution adopting higher temperature of the
first stage for nucleation than that of the second stage for crystallization was investigated. The results show that two-step temperature
process could control the crystal size and size distribution of ZSM-5. The result also shows that the time duration at higher temperature
for the acceleration of nucleation strongly affects the crystal size and size distribution. It implies that rapid nucleation at higher
temperature forms large number of nuclei followed by slow crystal growth probably due to the lack of energy at lower temperature. It
is very critical, therefore that the optimum time duration at higher temperature should be chosen to accelerate the nucleation within
initial stage.

buffaloli(金币+1,VIP+0):多谢!可否详细一些?
硅铝比范围小, 初试凝胶配比严格!
