China’s first 10,000-ton-class industrial demonstration plant for low-pressure ammonia synthesis using ruthenium-based catalysts
Thread Content
On March 7, China’s first 10,000-ton-class low-pressure ammonia synthesis industrial demonstration plant using ruthenium-based catalysts completed the calibration organized by the China Petroleum and Chemical Industry Federation in Suqian, Jiangsu. This move signifies the breaking of a foreign technological monopoly that has lasted for nearly 30 years; it will put an end to the high energy consumption pattern in China’s synthetic ammonia industry, and is expected to create opportunities for an increase in output worth hundreds of billions of yuan. It is reported that the core of this set of technologies is a new type of ruthenium-based ammonia synthesis catalyst jointly developed by Fuzhou University and Sanju Environmental Protection. The calibration results show that, compared with existing catalyst technology routes in China, this demonstration unit can significantly reduce the operating pressure and temperature for ammonia synthesis; preliminary estimates indicate that production capacity can be increased by approximately 33.6%, while the overall energy consumption per ton of ammonia can be reduced by more than 15%. Taking a plant with an annual output of 180,000 tons of synthetic ammonia as an example, it will save the enterprise over 30 million yuan in energy costs each year, while generating an additional output value of over 100 million yuan.
Jiang Lilong, director of the Fuzhou University Engineering Research Center for Fertilizer Catalysts and head of the innovation team in the key field of \"fertilizer catalysis\" under the Ministry of Science and Technology, told reporters that this team addressed the major needs of the ammonia synthesis industry by focusing on the development of new catalysts and innovations in related engineering technologies. It carried out systematic research on the technical challenges associated with industrial hydrogen production and ammonia synthesis. Through the efforts of two generations of researchers, it developed the \"stepwise sulfur-resistant shift reaction for hydrogen production\" and the \"iron-ruthenium alloy\" technology for ammonia synthesis, and created a world-first low-pressure ammonia synthesis system that uses coal as a raw material, integrating the stepwise shift reaction for hydrogen production with the iron-ruthenium alloy ammonia synthesis process. “If this technology is successfully rolled out, and assuming that half of the country’s synthetic ammonia production capacity is upgraded, it would be possible to save 5.5 million tons of standard coal per year, as well as reduce emissions of CO2, NOx, SO2, and other pollutants by tens of millions of tons – resulting in significant economic and environmental benefits. ”said Men Cungui, a professor-level senior engineer at the China Petroleum Consulting Center.
Congratulations! Was driving successful? What is used as the carrier for ruthenium-based catalysts? Thank you, OP; please reply. Waiting online
The successful development of this technology can reduce the energy consumption of domestic ammonia synthesis plants by about 15%. Coupled with increased production capacity and the replacement of outdated facilities, the economic benefits are substantial; moreover, the environmental benefits it brings are also significant. It is hoped that its use will be promoted as soon as possible!
Does the poster have contact information so I can learn more about the situation? Thank you
It is recommended to contact Sanju Environmental Protection or Jiangsu Heyou Chemical
I heard that production has stopped, but it’s not confirmed; it’s just a rumor
I began to pay attention to ruthenium catalysts over a decade ago; they are too expensive – one batch of such catalysts costs around 50 million. Even if their technical specifications are advanced, it would be better to spend a fraction of that amount on catalysts made from iron, since those can be produced in quantities of hundreds of tons, right?
Yes, today’s iron-based catalysts can also last for over 10 years. Have you heard of any catalysts that offer a better cost-performance ratio?
