Introduction:
      ZSM-5 zeolite with its unique three-dimensional cross-through channels and isomerization, shape-selective cracking and aromatization performance, can be widely used in petrochemical, chemical and other industries. In the fluidized-bed catalytic cracking reaction of FCC catalyst, added ZSM-5 has a good response effect for improve the gasoline octane number and increase in the olefin content of the gas.
     Use aluminum and silicate as the main raw material, in a certain ratio, under the conditions of high temperature and high pressure, then hydrothermal crystallization, after filtration, washing, and drying to obtain ZSM-5 zeolite.
 
Industrial applications:
1. Catalytic cracking
2. Diesel Pro hydrogen / non-hydrodewaxing catalyst
3. catalytic dewaxing
4. toluene disproportionation
5. xylene isomerization
6. alkylation
7. isomerization
8. aromatization
9. methanol conversion for production of hydrocarbons.
