[Ten years of major development in chemical technology] 147-2023 Carbon dioxide hydrogenation to methanol technology passed the scientific and technological achievements evaluation

Thread Content

Chemical science and technology has developed greatly in the past ten years, praising China's prosperity and strength. It is more lively and more exciting with everyone's participation. Everyone is welcome to participate in the forum to exchange and discuss. July fires, pay attention to fire prevention. -------------------------------------------------- On June 30, 2023, the "low-energy two-stage carbon dioxide hydrogenation to methanol technology" jointly developed by the Low Carbon Chemical Research Center of Sinochem Central Research Institute, Southwest Research Institute, and Luxi Group successfully passed the scientific and technological achievements evaluation organized by the China Petroleum and Chemical Industry Federation. The evaluation committee unanimously agreed: The overall technology of this achievement is at the internationally advanced level, and the catalyst performance has reached the international leading level. This project is oriented to the technical needs of carbon dioxide resource utilization and develops a new catalyst for high-efficiency carbon dioxide hydrogenation to produce methanol. Efficient activation of carbon dioxide is achieved under relatively mild reaction conditions, significantly improving carbon dioxide conversion rate, methanol selectivity and stability. ； A two-stage carbon dioxide hydrogenation to methanol synthesis, high-temperature separation, and thermal coupling process was developed to achieve low-energy and efficient conversion of carbon dioxide and significantly reduce overall energy consumption. In the next step, Sinochem China will rely on the Low-Carbon Chemical Research Center, based on independent patented technology and industrial test operation results, to develop a 100,000-ton carbon dioxide hydrogenation to methanol industrial demonstration device process package, bring this technology to the market, and promote green and low-carbon development of deep coupling between new energy and the chemical industry. The low-energy consumption two-stage carbon dioxide hydrogenation to methanol technology pilot plant was built in Luxi Chemical Industry. The project relies on the existing methanol distillation unit of Luxi Chemical Industry, uses a special catalyst (XNC-316) independently developed by Southwest Research Institute and a patented process of low-energy carbon dioxide hydrogenation to produce methanol, and uses carbon dioxide from the methanol washing unit and hydrogen from the coal hydrogen production unit to conduct a methanol pilot test. It will be commissioned in January 2023. In April 2023, it passed the 72-hour continuous on-site assessment organized by the China Petroleum and Chemical Industry Federation. The hydrogenation of carbon dioxide to methanol has a significant carbon reduction effect, which will help alleviate the carbon emission reduction pressure faced by Luxi Group in its development, consolidate the carbon dioxide-methanol-olefins-new materials/fine chemicals low-carbon industrial chain of coal chemical by-products, and improve the integration level of Luxi's industrial chain.
