Ruthenium-based low-temperature and low-pressure ammonia synthesis process makes another breakthrough

Demonstration device runs continuously and smoothly for 8,600 hours

The complete set of technology was jointly developed by Beijing Sanju Environmental New Materials Co.

The assessment expert group led by academician Shu Xingtian of the Chinese Academy of Engineering and senior engineer Men Cungui of the China Petroleum Consulting Center agreed that the reaction pressure of the low-temperature and low-pressure ammonia synthesis industrial device with iron-ruthenium relay catalysis is stable, the temperature of the ruthenium catalyst bed and the outlet of the synthesis tower is stable, and the reactor outlet The ammonia concentration and the net value of ammonia are stable, the ruthenium catalyst has high activity and stability, and the complete set of technologies and devices meet the requirements of industrial continuous production

Academician Shu Xingtian said: “The traditional ammonia synthesis industry uses iron-based catalysts for high reaction pressure, high temperature, high energy consumption, and low efficiency

Jiang Lilong, head of the project’s research and development team and director of the National Engineering Research Center for Fertilizer Catalysts, Fuzhou University, told the China Chemical Industry News that this technology has been successfully developed after two generations of hard work for more than 20 years.
