The first catalyst production plant in China was the catalyst department of Yongli Asia Plant, which was renamed as Nanjing Chemical Industry Company Catalyst Plant in 1959. In 1950, it started to produce AI type ammonia catalysts, C-2 type carbon monoxide high temperature conversion catalysts and VI type vanadium catalysts for sulfur dioxide oxidation, and then gradually completed the production of various catalysts for ammonia industry. By 1984, more than 40 units had produced catalysts for sulfuric acid, nitric acid and ammonia industries.
