(referred to as "Southwest Institute"), a subsidiary of Sinochem.* * Bid winning notice from Energy Group International Engineering Consulting Co., Ltd.: Southwest Hospital is in * * Energy Group Yulin Chemical once again defeated domestic and foreign competitors in the bidding for a 1.8 million tons/year large-scale methanol plant synthesis catalyst project and successfully won the bid. This is Southwest College and * * This is another cooperation between the energy group following the 1.8 million tons/year methanol unit synthesis catalyst project in 2022. * * The energy group operates multiple large-scale methanol production units. Among them, large-scale methanol synthesis units using DAVY radial water-cooled synthesis tower technology include Baotou, Yulin and other units. Each year, a large amount of foreign methanol synthesis catalysts are imported. Southwest Research Institute is the first scientific research institute in China to carry out research on low-pressure methanol synthesis technology and synthesis catalysts. The research on this technology has successfully broken the monopoly of foreign companies on low-pressure methanol synthesis technology. December 16-19, 2022 * * The energy group's 1.8 million tons/year coal-to-methanol unit uses the XNC-98-5 methanol synthesis catalyst independently developed by Southwest Research Institute and successfully completed the 72-hour performance assessment. On December 26, the unit load increased to 108%, the MTO-grade methanol output reached 259t/h, and all process indicators met the process requirements. Under the same load, the single-pass conversion rate is better than that of foreign catalysts, and the crude methanol selectivity is higher, marking a major breakthrough in the localization of synthetic catalysts for large coal-to-methanol units.
January 2023,* * The energy group's 1.8 million tons/year coal-to-methanol unit uses the XNC-98-5 methanol synthesis catalyst independently developed by Southwest Research Institute. When the unit load is increased to 108%, the output of MTO-grade methanol (referring to the raw material methanol that is suitable for the methanol-to-olefin unit) reaches 259 tons/hour. All process indicators meet the process requirements. Under the same load, the single-pass conversion rate is better than that of foreign catalysts, marking a major breakthrough in the localization of synthetic catalysts for my country's large-scale coal-to-methanol units.

Due to my country's resource situation of "rich coal, little oil, and lack of gas", it has become an inevitable choice to use coal to prepare bulk chemicals such as methanol to make up for the lack of oil and gas resources. Large-scale equipment can significantly reduce unit investment, energy consumption and production costs, so new coal-to-methanol units are all above one million tons in size. As of 2022, China's total annual methanol production capacity will be approximately 100 million tons, and the production capacity of large-scale methanol units above one million tons has accounted for 50%. While my country's methanol plants are developing in large-scale, methanol synthesis process packages and catalysts have long been dependent on imports, becoming one of the "stuck" key technologies in modern coal chemical industry. Therefore, it is beneficial to master the key independent technologies for large-scale coal-to-methanol production. * * Energy and economic security. Currently, the Davie radial water-cooling tower methanol synthesis process is used in China. The total production capacity of large-scale methanol plants that have been built or under construction is as high as 40 million tons. A large amount of money is spent every year to import foreign methanol synthesis catalysts, and there are also risks of long supply cycles and controlled key technologies. Southwest Research Institute is the first scientific research institute in China to carry out research on low-pressure methanol synthesis technology and catalysts. It shoulders the historical mission of completing the localization of large-scale coal-to-methanol synthesis technology and synthesis catalysts. In recent years, Southwest College has established a foothold in * * and industry needs, keep up with the development trends of methanol synthesis technology and catalyst technology in the world, and continue to carry out research and development and improvement of methanol synthesis technology and catalysts. This time, Southwest Research Institute's XNC-98-5 methanol synthesis catalyst was successfully put into use in the 1.8 million tons/year large-scale methanol synthesis unit of Guoneng Xinjiang Chemical Co., Ltd., breaking the long-term monopoly of foreign companies and taking a key step in the journey of localization.
On November 5, 2022, the 1.8 million tons/year coal-to-methanol unit of Guoneng Xinjiang Chemical Co., Ltd. successfully achieved full capacity production using the XNC-98-5 methanol synthesis catalyst independently developed by Southwest Chemical Research and Design Institute Co., Ltd., a subsidiary of Sinochem.
