面向工业过程碳减排的分子筛膜技术研究进展

Carbon emissions from industrial processes account for up to 70% in China. Energy saving and efficiency enhancement, clean fuels, CO₂ capture, etc. are the key pathway to achieve carbon emission reduction in industrial processes. High-efficient membrane separation has been deemed as a generic technology for energy saving, emission reduction and environmental protection. Focusing on carbon emission reduction, this paper summarized the main research progress in our group including organic solvent dehydration, clean fuel production, CO₂ separation, and chemical reaction intensification using zeolite membranes. Based on the more than ten years of experience on organic solvent dehydration, we proposed hollow fiber zeolite membranes for lower investment and membrane process optimization, which would be the key point for large-scale application. Since there is no practical application for industrial gas separation, it is highly desired to strengthen the preparation of high-/all-silica zeolite membranes and the separation of complex gas mixture. This would prove the way of zeolite membrane to practical application for gas separation.
