摘要
膜分离技术因其选择性高、成本低、绿色无污染等优点在碳捕集领域受到广泛关注.而复合膜由于其超薄的分离层结构,在气体分离上表现出均质膜所不具备的性能优势.本文介绍了膜法气体分离原理以及目前用于碳捕集技术的复合膜材料,综述了国内外用于碳捕集复合膜的应用及其研究进展.最后分析了复合膜在碳捕集领域所面临的挑战和未来的发展方向.
Abstract
Membrane separation technology has received wide attention in the field of carbon capture due to its advantages of high selectivity,low cost,green and non-polluting.Composite membranes,due to their ultrathin separation layer structure,show performance advantages in gas separation that homogeneous membranes do not have.This review introduces the principle of gas separation by membrane method and the composite membrane materials currently used in carbon capture technology,and summarizes the applications of composite membranes for carbon capture and their research progress at home and abroad.Finally,it analyzes the challenges and future development direction of composite membranes in the field of carbon capture.
