| Features | This type of catalyst is a new generation of catalysts developed in benzene process maleic anhydride catalyst series, which was successfully developed in 2020. Compared with the previous generation of catalysts, the product performance is better and the oxidation yield is high r. At present, most of the newly replaced plants use this type of catalyst.Provide matched catalyst loading and start-up technical services | |
| Development History | 2009 | The first generation of the product was successfully developed and applied in industry, and the oxidation yield reached to 91-92% |
2013 | The second generation of the product was successfully developed and applied in industry, and the oxidation yield reached to 93-94% | |
| 2015 | Optimized the product and achieved major breakthroughs with pe formance much superior to the level of imported catalysts in the s me year | |
| 2020 | The fourth generation of the product was successfully developed and applied in industry, and the oxidation yield reached to 96%-97% | |
