Abstract
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.
二氧化碳环化反应是获得高价值化学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 环加成仍是一项重大挑战。本文首次在膜分散增强型固定床反应器中成功实现了环碳酸酯的连续液相二氧化碳环加成反应。该反应器系统可稳定运行 100 h，生产率达到 15.9 g 环碳酸酯-h-1-gcat.-1，是传统固定床反应器的十倍以上。
期刊介绍：
Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline.
Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
