摘要
随着人类活动的增加和工业化进程的加速,温室气体排放导致的包括全球变暖等气候变化问题日益严重。含氟温室气体具有极高的全球变暖潜能值(GWP),会造成严重的温室效应,已受到国际公约的严格管控。综述了多种含氟温室气体(SF_(6)、NF_(3)、全氟化碳(PFCs)和三氟甲烷(R23)等)的膜分离技术及分离用膜材料的研究进展,重点分析了不同膜材料的选择性、渗透性和稳定性,探讨了通过优化膜组件结构与工艺参数升高含氟温室气体回收率和纯度的可行性。开发具有高选择性和稳定性的新型膜材料、优化膜组件设计以及探究复杂气体的分离方法是高性能膜材料的发展方向。
With the increase of human activities and the acceleration of industrializatio,climate change problems caused by greenhouse gas emissions,including global warming,are becoming increasingly serious.Fluorinated greenhouse gases have extremely high global warming potentials(GWP),causing serious greenhouse effects,and have been strictly regulated by international conventions.The research progress on membrane separation technologies and membrane materials for various fluorinated greenhouse gases(SF_(6),NF_(3),perfluocarbon(PFCs)and trifluoromethane(R23),etc.)was reviewed,with a focus on analyzing the selectivity,permeability and stability of different membrane materials.The feasibility of improving the recovery rate and purity of fluorinated greenhouse gases by optimizing membrane component structure and process parameters was explored.Developing new membrane materials with high selectivity and stability,optimizing membrane module design and exploring separation methods for complex gases are the research directions for high-performance membrane materials.
