The Datang SNG catalyst has become the first domestic methanation catalyst to fully replace imported catalysts
Thread Content
Domestic syngas methanation (SNG) catalysts can fully replace imported ones in terms of performance, according to news from the coal-to-gas production site in Keqi, Inner Mongolia, on August 15. The methanation reactors of the Datang Keqi coal-to-gas project were fully equipped with SNG catalysts developed independently by Datang Chemical Technology Institute starting from July 30. Half a month of continuous and stable operation has shown that their performance exceeds that of similar imported products, indicating that Datang’s SNG catalysts are the first domestic methanation catalysts to achieve complete substitution for imported catalysts. “After more than 10 years of effort, we have finally taken an important step forward on the path to localizing the key technologies for methanation. ”Li Chunqi, general manager of Datang Chemical Research Institute, explained that the institute began research on the domestic substitution of SNG processes and catalysts in 2007. It passed the evaluation of scientific and technological achievements conducted by authoritative organizations in 2014, completed industrial pilot tests by the end of 2016, and achieved partial substitution in the Datang Keqi coal-to-natural gas project for the first time in August 2018. After passing the expert review organized by the China Petroleum and Chemical Industry Federation, partial catalyst substitution was implemented in the Jinmei Tianqing and Yili Xintian coal-to-natural gas projects earlier this year. The development and application of Datang SNG catalysts have progressed step by step, completing the entire process of domestic substitution and enhancing the independent innovation capabilities of domestic coal-to-natural gas projects.
It is understood that all domestic coal-to-natural gas production facilities that use the DAVY methanization technology have been equipped with Datang SNG catalysts, whose overall performance is superior to that of imported catalysts. In addition, the Datang SNG catalyst is suitable not only for high-temperature methanation processes using syngas as a feedstock, but also for high-temperature methanation processes and isothermal methanation processes using coke oven gas as a feedstock. This catalyst has been operating stably in the high-temperature methanation unit using coke oven gas at Beijing Sanju Company for over 1 year, and in the isothermal methanation unit using coke oven gas at Inner Mongolia Jianyuan for over half a year. Its activity and lifespan far exceed those of similar catalysts. China currently has 4 coal-to-natural gas projects in operation, with a total annual production capacity of 5.1 billion cubic meters. The key core technologies used—namely the SNG process technology and catalysts—are all imported from abroad. Since 2020, due to the impact of the COVID-19 pandemic, imported SNG catalysts could not be supplied in a timely manner. As a result, both the Jinneng Tianqing and Yili Xintian coal-to-natural gas projects opted to use Datang SNG catalysts as a partial substitute, thereby overcoming the problem of having no catalyst available and preventing major production accidents. SNG catalysts and processes are at the core of coal-to-natural gas technology. The successful localization of catalysts by Datang Chemical Engineering Institute has resolved the key issue for the long-term development of coal-to-natural gas projects.
How are the 4 coal-to-natural gas projects that have been put into operation in our country performing currently? https://bbs.hcbbs.com/thread-3247768-1-1.html (Source: Haichuan Chemical Industry Forum)
On December 18, 2018, the “Industrial Application Evaluation Meeting for Datang Complete Methanation Catalysts,” organized by the China Petroleum and Chemical Industry Federation (hereinafter referred to as the “Petrochemical Federation”), was held on-site at Inner Mongolia Datang International Kesikteng Coal-to-Natural Gas Co., Ltd.
