CO2 cycloaddition is an effective approach to achieve high-value chemical products and mitigate greenhouse gas emissions. However, high-efficiency and continuous CO2 cycloaddition keeps a significant challenge. Herein, continuous liquid-phase CO2 cycloaddition to cyclic carbonate is successfully realized for the first time in a membrane dispersion enhanced fixed-bed reactor. The reactor system can be operated steadily for 100 h with a productivity of 15.9 gcyclic carbonate·h−1·gcat.−1, more than ten times that of the traditional fixed-bed reactor.

在膜分散增强固定床反应器中对环状碳酸盐进行连续 CO2 环加成反应


CO2 环加成是实现高价值化工产品和减少温室气体排放的有效方法。然而，高效和连续的 CO2 环加成仍然是一个重大挑战。在此，首次在膜分散增强固定床反应器中成功实现了对环状碳酸盐的连续液相 CO2 环加成反应。该反应器系统可以稳定运行 100 小时，生产率为 15.9 gcyclic carbonate·h−1·gcat.−1，是传统固定床反应器的十倍以上。
