On May 24, the Institute of Process Engineering of the Chinese Academy of Sciences announced that a set of green and low-carbon technologies for synthesizing carbonates from carbon dioxide using ionic liquids as catalysts has recently passed the evaluation conducted by the China Petroleum and Chemical Industry Federation. Industrial plants with a capacity of 100,000 tons per year have been operating steadily for 14 months now. The ionic liquid team at the Institute of Process Engineering, Chinese Academy of Sciences, has designed and developed ionic liquid catalysts that utilize the synergistic effects of cations and anions, as well as the technologies for their large-scale production. They have overcome key challenges such as achieving uniform gas-liquid distribution in large-scale ionic liquid reactors and ensuring efficient coordination between reaction processes and mass transfer. A new reaction system based on sequential conversion, falling film separation, and closed-loop circulation has been developed, along with technologies for enhancing the coupling between reaction and separation processes and for optimizing the utilization of energy at various levels. A 100,000-ton industrial facility for the catalytic conversion of carbon dioxide into carbonates using ionic liquids. This achievement was developed through collaboration between the ionic liquids research team at the Institute of Process Engineering, Chinese Academy of Sciences, and companies such as Shenzhen Xinzhoubang Technology Co., Ltd.; it represented a systematic innovation in terms of ionic liquid catalysts, reactors, and the overall manufacturing process. Through joint efforts, a 100,000-ton industrial facility for this purpose was built in the **-class petrochemical zone in Daya Bay, Huizhou, Guangdong. Since March 2021, it has been operating stably for 14 consecutive months; the carbonate products (including ethylene carbonate and dimethyl carbonate, etc.) meet electronic-grade standards, while the ethylene glycol products meet polyester-grade standards. The system’s energy consumption has been reduced by 37%. The outstanding advantage of this achievement is the use of carbon dioxide emitted from industrial processes to produce electronic-grade carbonates while simultaneously generating polyester-grade ethylene glycol, which further enhances the economic efficiency of the entire system and overcomes the challenges that have hindered its large-scale application.
