Application of ZSM-5 molecular sieve

1. Application in the field of oil refining industry

Diesel hydrodecondensation, catalytic dewaxing of lubricating oil, recovery of gasoline octane number, catalytic cracking gasoline olefin reduction, aromatics shape-selective conversion and methanol shape-selective conversion, etc.

2. Application in the field of fine chemicals

Synthesis of 1,4-dioxane from diethylene glycol, synthesis of MTBE (methyl tert-butyl ether) from isobutylene and methanol, synthesis of 3,5-dimethylpyridine, etc.

3. Application in the field of environmental protection

The application of ZSM-5 in the environmental protection industry is mainly reflected in its strong adsorption capacity for VOCs and good effect. It can be used for the removal of thiophene, phenol, trichloroethylene, NOx conversion to N2, formaldehyde removal, H2S removal, etc.

4. Application in chemical corrosion protection

Most of the liquids flowing through chemical equipment and pipelines are corrosive, which can easily corrode pipelines and equipment, greatly reducing their performance and the safety of the production process. ZSM-5 molecular sieves are resistant to corrosive liquid acids except hydrofluoric acid, and can effectively resist the corrosion of hydrochloric acid, nitric acid, phosphoric acid and sulfuric acid.

5. Application in electrochemistry

Due to the characteristics of high energy density, good safety and easy portability, all-solid-state lithium polymer batteries (LPBS) may be one of the most used chemical power sources in the future and have good application prospects.
