Abstract:

As an important chemical raw material and intermediate produced from CO2 utilization, ethylene carbonate has attracted more and more attentions. However, there are common problems in the production process, such as high energy consumption for purification of ethylene oxide, low catalytic efficiency in the reaction, and complex process. In this paper, the absorption and conversion units of ethylene oxide and the production process of ethylene carbonate were reviewed. The types of absorbents, the kinds of catalysts as well as the catalytic mechanism and the production process were summarized emphatically. Finally, based on the production technology of ethylene carbonate, the urgent problems and challenges in this research field were discussed. It was also pointed out that the development of multi-site ionic liquid catalysts and the application of absorption-conversion coupling processes would become the highlights of future research and have good industrialization prospect.

Key words: absorption, recovery, catalysis, ethylene oxide, ethylene carbonate
