中空纤维陶瓷膜介导微气泡制备与CO2合成环状碳酸酯
Microbubble generation mediated by hollow fiber ceramic membrane for the synthesis of cyclic carbonates from CO2
摘要
Abstract
To address the challenges in the controllable preparation of microbubbles and their application in chemical reac-tion intensification,a heterogeneous membrane reactor was constructed using hollow fiber ceramic membranes for efficient controllable generation and rapid characterization of microbubbles.Furthermore,its application in the synthesis of cyclic carbonates from CO2 was investigated.The effects of membrane length,pore size,number of membranes,liquid-to-gas ratio,and gas-liquid flow mode on microbubble size were systematically investigated.The experimental results showed that when the membrane length was 15 cm,the pore size was 0.3 μm,the single-layer membrane,the liquid-to-gas ratio was 18,and the liquid flowed inside the membrane while gas flowed outside,microbubbles with a diameter of 46-152 μm could be continuously generated.When this membrane re-actor setup was employed for cyclic carbonate synthesis through CO2 cycloaddition,epichlorohydrin conversion up to 81.9%and a cyclic carbonate yield of 74.05%could be obtained at ambient temperature and atmospheric pressure.关键词
