ZSM-5

 
1. ZSM-5 zeolite is a high-silica zeolite, and has a Si/Al ratio of more than 1000, and also shows hydrophobic properties.
 
2. The structural feature of ZSM-5 zeolite is that the vertical and horizontal parts are crystalline aluminosilicates composed of ten-element channels. The basic structure consists of eight 5-membered rings, which have only channels and no cageless cavities.
 
3. ZSM-5 has two sets of cross channels, one of which is elliptical with a window diameter of 0.55 to 0.60nm. Since the shape of the reaction space and the channel are similar, the zeolite has a shape selection effect on the reactants and products.
 
4. In addition, because of its harmonious structure and good hydrothermal stability, ZSM-5 is a good raw material for selective catalysts.

ZSM-5 application

 
ZSM-5 type zeolite is widely used in the petrochemical industry, as an auxiliary agent for fluidization, catalytic and cracking processes, can produce more propylene and liquefied gas, and increase the octane number of gasoline. In addition, the zeolite can also be used in the production of ethylbenzene, xylene, phenol, pyridine, etc.

ZSM-5 features

 
Large-scale ZSM-5 zeolite crystals synthesized in a fluoride medium show amazing activity, stability, and selectivity to light olefins in methanol-to-olefin (MTO) reactions. Through proper control of synthesis parameters, ZSM-5 single crystals of unprecedented high quality can be produced. SEM, HRTEM, CO-FTIR, 27 Al and 19 F MAS-NMR, Rietveld structure refinement and flatness proved that there are no usually uncontrollable variables, such as structural defects, external non-selective surface acid sites and aluminum outside the framework ( EFAl) species. N 2-and argon adsorption measurement. Interestingly, the diffusibility of different probe molecules (toluene, benzene, and neopentane) has been evaluated by PFG-NMR, which allows light to be projected on interesting structure-diffusion-activity relationships. The “suspension” effect can be proved through experiments, and its impact on catalysis has been highlighted in the rationalization attempt: the diffusion model based on Maxwell-Boltzmann can correctly predict the product of this counter-intuitive methanol-to-propylene (MTP) catalyst distributed.
