Z5含铝，s-1没有Al ，纯硅分子筛
zsm-5和silicate-1都是mfi型的，但是晶胞参数不一样，所以体现在xrd峰的位置会有变化，
在ZSM-5外层包覆没有酸催化活性的纯硅沸石(Silicalite-1)是一种有效改善催化剂寿命的手段.本文在TPAOH体系中,通过水热法,考察了MFI拓扑结构沸石进行包覆形成MFI@MFI结构的可行性.在此基础上,设计合成了三种具有相似硅铝比,但铝分布不同的催化剂(ZSM-5@S-1, ZSM-5, S-1@ZSM-5),并用于甲醇制丙烯(MTP)...

zsm-5晶化后是成玻璃状固体的。按照文献合成出单质硫S+1,3-diisopropenylbenzene(DIB)，合成过程很简单，得到产物是玻璃状粘稠的聚合物，摊平放阳光下曝晒几填就成了玻璃状固体。

Thus, microwaves promote the catalytic reaction by selectively heating zeolite cations without any susceptors. In this study, we demonstrate that Na+ substituted ZSM-5 (Na-ZSM-5) promotes the selective catalytic cracking of methyl oleate into lower olefins under microwave irradiation. Na-ZSM-5 was...
Acid sites located on the external surface of H-ZSM-5 crystallites were selectively neutralized by a mechanochemical method with BaO supported on spherical silica particles. This effect was confirmed by both NH3-TPD measurement and comparing the catalytic properties of unmodified and modified H-ZSM-...

To better understand external surface barriers on hierarchical ZSM-5 zeolite, SiO2 layers were constructed over zeolite nanocrystal by using chemical liquid depositions (CLD). Diffusion measurement showed that the apparent diffusion rate over the zeolite was increased by up to 142 % after SiO2 deposit...
