本論文は燃焼後CO2回収に用いられる分離技術を包括的にレビューしたものである。膜分離、物理吸収、化学吸収、深冷分離、吸着の各手法を比較し、長所と短所を評価している。アミン溶液による吸収とメソポーラスシリカへの吸着が実用上主流であり、膜は選択性に優れるが化学的・機械的耐久性に課題がある。最適技術の選定には技術的・経済的検討が不可欠と結論づける。
English
This review comprehensively surveys CO2 separation technologies for post-combustion capture, comparing membrane filtration, physical and chemical absorption, cryogenic processes, and adsorption. Amine-based absorption and mesoporous silica adsorption are the most widely used, while membranes offer selective capture but suffer poor chemical and mechanical durability. The authors conclude that selecting the optimal technique requires careful technological and economic assessment before industrial deployment.

📄 Abstract（原文）
Global warming is a major challenge worldwide whose main cause is thought to be due to CO 2 emission, which is generated by both human as well as natural sources such as combustion of fossil fuels and industrial activities. A variety of processes are being widely employed for the capture of CO 2 , as the main greenhouse gas, from combustion of flue gases. Analyzing the most significant technological advancements in CO 2 separation is the goal of the presented research which provides a great framework to realize advantages and disadvantages of each method. Different separation processes were analyzed, and the advantages and disadvantages of each method were evaluated. The considered processes included membrane filtration, physical absorption, chemical absorption, cryogenic processes, and adsorption techniques. Absorption with amine solutions and adsorption with mesoporous silica are amongst the commonly used processes in CO 2 capture. Their underlying parameters are reviewed and discussed in this study. Membranes are also efficient in selective CO 2 capture, however their chemical and mechanical strength is poor, particularly for polymeric membranes. In conclusion, choosing the best technique for CO 2 capture separation is a complicated matter, and before being used on an industrial scale, a number of technological and economic considerations must be made.
