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

2013

Start R&D work

2013

R&D succeeded, started production and sales.

In 2015, a 3-cyanopyridine plant was used for the first time in Shandong, and has been in continuous use for more than 9 years by 2024, with stable performance.

In 2018, a new 3-cyanopyridine plant in Shandong was used for the first time and has been in continuous use for more than 6 years by 2024, with stable performance

More new 3-cyanopyridine devices are under negotiation and waiting for the start of the project。
